Side-by-Side Photo Maker — Put Pictures Side by Side Online

What you can customize in this side-by-side image maker

The editor is designed for people who need more than a one-click merge. You can start with a side-by-side photo, a stacked picture, a standard grid, a feature-panel composition, an editorial mosaic, or a film-strip layout. From there, shape the output for a product comparison, portrait pair, before-and-after graphic, image portfolio, or social post.

The simplest workflow is still short: add photos, choose one of the four common automatic layouts or Custom collage, and download. In Custom collage mode, drag a frame to move it, use the corner handle to resize it, switch to crop mode to move the image inside the frame, and use the zoom slider in either direction. Precise sliders and keyboard controls provide alternatives when dragging is awkward.

These features support different jobs without requiring the same look for every result. Use simple settings when the goal is direct comparison; reach for textures, typography, or a mosaic only when they make the finished picture easier to understand.

How to make a side-by-side photo

Use the photo maker above to put two pictures side by side in one image. If you want to make pics side by side or put photos side by side for a comparison, the crop and layout options let you keep control over the final result instead of forcing you into a fixed template.

1. Add two or more photos. Choose files, drag them onto the upload area, or paste an image from your clipboard. The tool accepts common browser-readable image files.
2. Arrange the pictures. Choose Side by side for a horizontal pair, Top & bottom to stack the pictures, or a grid layout for three to twelve images. Reorder photos with the arrow buttons in each photo card.
3. Set the crop and proportions. Pick a tile shape and decide whether to crop each photo to fill its tile or fit the entire image inside it. Expand a photo's crop controls to adjust its zoom and focal position.
4. Style the spacing. Change the gap, outer padding, background color, corner radius, frame, and optional labels until the side-by-side picture looks right.
5. Preview and export. Check the displayed dimensions, choose PNG, JPG, or WebP, and download the final collage. The output is a single image file.

Choose the right side-by-side image layout

A side-by-side photo places two images in neighboring panels, usually at the same size. It is ideal for a direct comparison because viewers can inspect both images at once. A stacked layout places one picture above the other, while a photo grid is more useful when you have several angles or stages to show. For side-by-side pics, consistency in crop and scale often matters more than decorative effects.

For only two images, a simple horizontal or vertical composition is usually the clearest choice. A multi-photo grid is still a useful side-by-side image maker option when a comparison requires more than a pair.

Crop to fill or fit the whole photo?

Crop to fill each tile

Crop-to-fill, also called cover, makes every tile edge-to-edge. The tool preserves the image's proportions and trims the parts that fall outside the tile. Use it when alignment and a consistent panel shape matter more than showing every pixel, such as product grids or matched portraits. The per-photo zoom and focus sliders help keep faces, objects, or other important details in view.

Fit the entire photo

Fit-whole-photo, also called contain, starts with the complete source image visible without stretching it. Increasing zoom can intentionally enlarge it beyond the tile edges; return zoom to 1× to restore the full-image fit. If its shape does not match the tile, background color will show around the photo. Choose this mode when cutting off any part of the image would hide important context—for example, screenshots, documents, artwork, or a comparison where all edges must remain visible.

What can you use a side-by-side photo collage for?

Before-and-after photo comparisons

Place an original photo beside an edited result to make retouching, color correction, restoration, renovation, or other visible changes easier to understand. Keep the angle and scale reasonably consistent. Labels such as “Before” and “After” help viewers understand the order at a glance.

Product photos and shopping comparisons

Put product pictures side by side to show alternate colors, versions, packaging, details, or angles. Use a consistent background and tile ratio when a tidy catalog-style presentation matters. Avoid implying two products are identical if lighting, perspective, or scale differs materially.

Portraits, travel, and personal photos

Create a pair of portraits, compare two poses, place trip highlights together, or assemble a small photo story. For social posts, select a final canvas size with the destination in mind and preview the finished image at a smaller scale before sharing it.

Photography portfolios and client proofing

A diptych—a composition of two images—can show alternate edits or neighboring frames in a portfolio. For client review, simple spacing and readable labels can make the options easier to discuss without asking someone to open separate files.

Design, tutorials, and presentations

A picture side by side with a second screenshot or example can explain a change more quickly than separate images. Use the fit-whole-photo setting for screenshots containing text, and choose PNG when hard edges or small lettering need to stay crisp.

Choose the right side-by-side photo maker for your task

A side by side photo places two or more pictures in one composition so viewers can compare them without switching between files. If you are learning how to make a side by side photo for a before-and-after story, keep the angle and subject scale consistent. For product work, place pictures side by side with a similar crop and background; for a tutorial, use enough spacing to make the important details easy to follow.

When a simple photo pair is best

Side by side photos are useful for comparing edits, product colors, alternate portraits, renovation progress, or two moments from a trip. To make pics side by side, upload the images, choose the horizontal layout, check the focus of each crop, and export one combined image. If a tall phone layout is more appropriate, switch to Top & bottom rather than squeezing the pictures into narrow panels.

Maker, editor, or picture generator?

People may describe the same task as a side by side photo maker, side by side picture maker, side by side image maker, or side by side photo editor. A basic generator can merge photos; an editor also gives you control over crop, rotation, brightness, contrast, labels, frames, and output dimensions. Here, a preset is only the starting point: each setting remains adjustable before the final image is saved.

If you were looking for a side by side picture generator or a side by side photo generator, choose a visual design and then replace the sample pictures with your own. You can put images side by side, create a grid of multiple pictures, or turn a picture side by side with another photo into a labeled comparison. The result is a flattened PNG, JPG, or WebP file—not a layered project for a separate editor.

For a photo side by side comparison, prioritize matching scale and a clear label over decorative styling. When preparing side by side pics or other side by side images for a website or social post, select the canvas dimensions first and inspect the exported version at its likely display size.

Image size, aspect ratio, and export quality

The final dimensions depend on the chosen canvas width, layout, tile ratio, gaps, and padding. For a horizontal two-photo collage, the width includes both image panels plus the gap and outer padding. Its height follows the selected tile ratio. Stacking photos makes the output taller; a grid divides the available width among more panels.

Choosing a canvas size

• 1080 px wide: a practical starting point for many digital graphics and social posts.
• 1600–2400 px wide: useful for website content, presentations, and general-purpose sharing.
• 3000–4096 px wide: provides more pixels for large displays or later resizing, but can increase memory use and export time.

These are flexible working sizes, not guarantees for a platform's current display rules. Check the destination's latest specifications before creating assets for a specific placement. If the collage is intended for print, calculate the required pixel dimensions from the physical print size and target pixels per inch (PPI).

PNG, JPG, or WebP?

The quality slider applies to JPG and WebP exports. PNG does not use that quality value. The page builds the collage on a canvas and asks the browser to encode the selected output format, so exact file size depends on the images, dimensions, browser, and format.

Tips for making a clearer side-by-side picture

• Match the framing. Keep the subject at a similar scale when the goal is to compare changes rather than different compositions.
• Use a purposeful gap. A small gap separates the panels; no gap creates a continuous split image; a wider gap can create more visual breathing room.
• Choose contrast carefully. A neutral background often works for products and portraits. Use a color that separates the pictures without competing with them.
• Label only when needed. Short labels such as “Before,” “After,” “A,” and “B” add context. Long labels can cover important details.
• Check the crop at full size. Cover mode can cut off faces, text, or product edges. Adjust focus or switch to Fit the whole photo where necessary.
• Keep the original files. The collage is a new combined image, not a replacement for the source photos. Retain originals when you may need to re-edit or produce a different layout.

Supported files and important limitations

This side-by-side photo editor is designed for common image formats that the current browser can decode: JPG/JPEG, PNG, WebP, GIF, BMP, and browser-supported AVIF. An animated GIF is treated as a still image using the frame exposed by the browser; this tool does not create an animated collage. HEIC/HEIF, SVG, camera RAW, and other formats may not decode in a browser file input and are not listed as supported input types.

Images are read locally and drawn to an HTML canvas in this page. The code does not send source images to an upload API. Browser memory and canvas limits vary by device and browser; very large original images or a very high output size may fail. If that happens, reduce the output width or use fewer photos. This tool does not perform AI upscaling, retouching, color matching, perspective correction, or automatic subject detection.

Canvas export can also be affected by browser support for a particular output format. If WebP export is unavailable in a browser, choose PNG or JPG. To copy the rendered image directly, the browser must support clipboard image writing and the page must run in a secure context; downloading remains the fallback.

Side-by-side picture templates: how to choose a useful starting point

A template is best treated as a visual starting point, not a rule. The right arrangement depends on what readers need to notice first. A straightforward two-panel split makes comparison immediate; an editorial mosaic creates hierarchy when one photo matters more than the others; a film-strip composition is useful when the sequence itself tells a story. The design library above lets you browse these directions visually and then adjust the crop, colors, labels, and dimensions for the specific photos you have.

Choose a template by job, not just by appearance

Every preset is editable. Change the palette if it competes with a photo, remove labels when the images explain themselves, and switch to a simpler split when viewers need direct comparison rather than a decorative design.

Backgrounds, gradients, and texture: use contrast with intent

The background fills the space between panels and around the outer edge. A solid neutral is the most predictable choice for product photos, catalog work, and detailed comparisons. A subtle gradient can give a social graphic more depth, while a light dot or grid pattern can add structure to a presentation without needing another image asset. The tool's pattern picker offers multiple families and color variations, and the preview shows the actual treatment that will be included in the exported file.

When to use a solid background

White, off-white, charcoal, and restrained gray are useful when the image itself should carry the message. White can blend into a white page, so a narrow frame or slightly warmer background may help distinguish the tile edges. Dark backgrounds can add contrast to light products, but check that shadow detail and dark hair remain visible.

When a gradient or pattern helps

A gradient is useful for social creatives, title cards, or presentation boards where some personality is welcome. Patterns are best kept subtle: lower the texture strength if the gaps begin to compete with fine image details. If the collage is a comparison intended to support a decision, decorative effects should not change how the subject appears or distract from important differences.

Adjust each photo independently before combining images

Photos shot on different cameras or under different lights can look mismatched even when their dimensions are correct. Use the per-photo controls to rotate a sideways image, flip it when appropriate, and make careful brightness, contrast, saturation, and monochrome adjustments. These settings are applied during rendering, so you can change one image without having to edit and save a separate copy first.

Crop positioning is not the same as resizing

Zoom and focus controls decide which part of an image occupies a tile. They do not add detail to the source photo. A tighter crop can emphasize a small feature, but it can also remove context. For reliable comparisons, start with similar framing and use the same visual scale wherever practical.

Keep a neutral baseline

Brightening a dark image may improve visibility, but strong saturation, contrast, or warmth changes can make two photos harder to compare fairly. For a creative collage, a style treatment may be appropriate. For product, real-estate, documentation, or before-and-after images, use adjustments conservatively and disclose material edits when the context calls for it.

Side-by-side collage dimensions and social image ratios

The output ratio describes the shape of the complete collage, not an individual source photo. A square canvas is convenient for a square social post, a 4:5 portrait canvas leaves more vertical room in a feed, and 9:16 is a tall format used by many story-style placements. A landscape ratio such as 16:9 works well for video thumbnails and horizontal presentations. Platform specifications can change, and each service may crop or display uploads differently, so check the current destination guidance when exact placement matters.

These are practical starting dimensions rather than guarantees for every platform. The output-width control and custom canvas-height option let you test a target composition without forcing every collage into one format.

Exporting a collage: PNG, JPG, WebP, and quality settings

The export choice affects file size, compression, compatibility, and how edges are reproduced. PNG is lossless and useful for graphic edges, clean labels, or a design that needs exact flat colors. JPG is widely supported and typically efficient for photographic content, but it uses lossy compression. WebP is a modern option for web use; verify that the receiving app or publishing workflow accepts it.

Why output dimensions matter

Increasing the canvas dimensions can make a file larger, but it does not restore source detail that is absent. If the original photo is small, the collage can still appear soft when enlarged. For crisp output, use suitable source images, avoid needless repeated re-encoding, and inspect the downloaded file at the size it will actually be displayed.

Quality is a trade-off, not a magic sharpness control

The JPG/WebP quality setting adjusts encoding quality and file size. A higher value generally retains more visual information while making a larger file; the exact result varies with subject detail and browser encoding. PNG ignores the lossy quality slider. If a download fails, lower the output dimensions before repeatedly trying a very large canvas, especially on a phone with limited available memory.

Practical workflows for different kinds of side-by-side pictures

Before-and-after photographs

1. Choose the original and updated images in the intended order.
2. Use the equal split template and match the zoom and focus points.
3. Add short “Before” and “After” labels if the order is not immediately obvious.
4. Keep the background neutral and review whether any crop hides relevant context.
5. Export at a suitable dimension and keep the source files for future revisions.

Product comparisons

1. Place the two product views at a similar scale.
2. Use the Fit option when complete packaging, shape, or edges need to remain visible.
3. Use consistent background and frame settings across both panels.
4. Add concise option labels when the images represent distinct models or colors.
5. Review that lighting and edits do not imply inaccurate product attributes.

Portfolio and case-study images

1. Select a wider canvas and an editorial or mosaic layout when one image is the lead.
2. Choose a palette drawn from the portfolio's own visual identity.
3. Keep captions brief and use enough margin to separate images from the page background.
4. Check both the preview and exported dimensions before placing the file in a page or presentation.

Social graphics

1. Pick the destination canvas preset before finalizing the crop.
2. Reduce the number of panels if labels become too small on a mobile screen.
3. Use readable foreground/background contrast and leave room around text.
4. Inspect the image at a smaller preview size to find text that will be hard to read on a phone.

Make side-by-side images easier to understand and access

A collage is a visual summary, but it should not be the only place where essential context appears. When adding a collage to an article or product page, supply meaningful alternative text that describes the comparison rather than stuffing the alt attribute with every related keyword. If the exact differences matter, explain them in nearby text as well. This helps readers who cannot see the image clearly and gives everyone a clearer understanding of why the two panels are shown together.

For labels inside the image, use concise words and strong contrast. Avoid tiny type, faint gray on white, or using color alone to communicate which panel is “before” or “after.” The exported collage is a flattened image; its canvas text is not individually selectable by screen readers, so repeat important text in the surrounding page when needed.

How image processing and project recipes work

This implementation uses the browser's image decoding and canvas APIs to create the composition. The tool code contains no endpoint that uploads the selected photo files for remote collage processing. Normal website infrastructure—such as WordPress, hosting, caching, or site analytics, if installed separately—can still make its own network requests. The recipe export stores visual settings and per-image adjustment values, not embedded photo data. Importing a recipe therefore restores the design settings, after which you choose the source images again.

For privacy-sensitive material, follow your organisation's policies before using any website tool and avoid uploading images you are not permitted to process. Browser-local processing does not determine who owns a photo, remove identifying details from its pixels, or automatically erase metadata from every final format.

What a side-by-side photo maker does—and what it does not do

A collage maker arranges decoded images into a single flat output. This page supports composition, crop positioning, visual treatments, text overlays, patterns, dimensions, and common raster exports. It does not automatically discover the best crop, identify objects, remove backgrounds, restore damaged photos, upscale detail with AI, synchronize color scientifically, or decide whether a before-and-after comparison is fair. Those tasks require different processing or human judgement.

Input support depends on the current browser's image decoder. Common formats such as JPEG, PNG, WebP, GIF's currently decoded frame, and BMP are accepted by the file picker when they can be decoded. HEIC/HEIF, RAW camera files, SVG, and unusual or corrupt images may need conversion before use. The practical maximum output is limited by both the tool's safeguards and the device's available memory.
