Free Online Screen Recorder
Record your screen, tab, or window with microphone or system audio. Unlimited time, no sign-up, no watermark. Runs entirely in your browser.
What this screen recorder does
This free online screen recorder captures your screen, browser tab, or specific application window along with your microphone or the tab’s system audio — all directly in your browser using the native getDisplayMedia and MediaRecorder APIs. No software to install, no account to create, no watermark on the output, and no upload to any server. When you click Stop, the recording appears on the same page ready to preview and download as a WebM or MP4 video file.
How to record your screen
- Pick what to capture — screen only, screen + microphone, screen + system audio, or all three combined.
- Pick a quality — 720p is the recommended default (great balance of clarity and file size). 1080p for professional use; 480p for quick screenshots.
- Click Start Recording. Your browser will show a permission dialog asking which screen, window, or tab to share. Select the source you want to record.
- Do your recording. The timer counts up in real time. Click Pause anytime and resume later, or click Stop when you’re done.
- Preview and download. The recording appears below the tool with a video player. Click Download Recording to save it to your device.
Audio recording options explained
Screen only (no audio) — Silent recording. Perfect for creating GIFs or when you’ll add audio in post.
Screen + Microphone — Your voice from the mic is included. This is the standard mode for tutorials, walkthroughs, and voice-over demonstrations.
Screen + System Audio (tab audio) — When recording a browser tab, the tab’s audio (video playing, music, alerts) gets captured. Great for recording video content or web-app demos. Note: this works reliably only when you choose “Chrome tab” in the source picker.
Screen + Mic + System Audio — All three combined. Ideal for reaction videos, gaming captures with commentary, and any recording where you narrate over playing content.

Common use cases
Tutorial creators and course authors — Record step-by-step walkthroughs of software or websites with voice-over. Import the download into your favorite editor to add captions, or upload directly to YouTube.
Bug reports — Nothing communicates a bug faster than a video showing exactly how to reproduce it. Include a screen recording in your GitHub issues, Jira tickets, or support emails.
Product demos — Record a walkthrough of your app for sales demos, investor pitches, or user onboarding videos.
Gameplay clips — Capture browser-based games or share the current tab of any streaming service (subject to that service’s terms).
Video meetings and lectures — Record a lecture or interview when the meeting platform doesn’t offer built-in recording. Just be sure to inform participants first — recording conversations without consent is illegal in many jurisdictions.
Asynchronous team communication — Instead of a long email, record a 60-second screen video showing your team what you mean. Loom-style videos, without the Loom account.
Content creators — Record short clips to embed in social media posts, blog articles, or newsletters.

Which browser works best?
- Chrome / Edge — Best support. All three audio modes work. Can pick entire screen, a window, or a browser tab.
- Firefox — Full video recording. System-audio capture is limited to certain scenarios.
- Safari 13+ — Full video recording. May not offer system-audio capture; use screen + microphone instead. Outputs MP4 by default.
- Mobile browsers —
getDisplayMediais not supported on iOS Safari or Android Chrome. Use the browser’s built-in screen recording via the phone’s Control Center or Quick Settings, then transfer the file.
Pro tips
- Test your setup first. Do a 10-second trial recording before starting a long tutorial. Confirm the audio you expect is being captured.
- Choose “Chrome Tab” not “Entire Screen” when recording browser content — this lets you capture tab audio and gives a cleaner, notification-free video.
- Close unrelated tabs and apps. Every extra process running slows the encoding and can cause dropped frames at 1080p.
- Speak clearly and pace yourself. Screen recordings are much harder to edit than live speech — get it right the first time when possible.
- WebM files play everywhere modern. If you need MP4 specifically (older editors, some social platforms), convert with our upcoming Video Converter tool or use a service like HandBrake locally.
- Files can get big fast. A 720p recording is roughly 25-40 MB per minute. A 30-minute 1080p recording can exceed 2 GB — consider stopping and starting fresh recordings for very long content.
Frequently asked questions (FAQs)
No. Recording happens entirely in your browser using the native MediaRecorder API. The file exists only in your browser’s memory until you download it.

WebM (Chrome, Firefox, Edge) or MP4 (Safari and some Chrome versions). Both play everywhere modern and can be converted if needed.

Screen recordings are uncompressed compared to hand-edited video. Expect ~25-40 MB per minute at 720p, 60-90 MB at 1080p. Use our upcoming Video Compressor to shrink files afterward.
