Free Online Screen Recorder

The recorder uses the screen-capture, camera and microphone features built into your browser. When you press Start, the browser itself asks what you want to share, and nothing is captured until you choose. The video is encoded on your computer as you record.

The footage is never sent anywhere. There’s no server that receives it, so there’s nothing to upload, wait for or delete later. While you record, the file is written every second to the browser’s private on-device storage, which is what lets the page recover a recording after a crash. When you save, the finished file lands on your computer like any other download. When you use Share…, your system passes the file directly to the app you pick, with no server in between.

You don’t have to take this on trust. Open your browser’s developer tools and watch the Network tab while you record: no video leaves the page. Or load the page once, switch off Wi-Fi and record anyway. After the first visit it works offline.

Your microphone works in every desktop browser. Capturing the sound your computer plays is where browsers and operating systems differ, and it also depends on what you choose to share.

• Windows, in Chrome or Edge: share the entire screen and tick “Also share system audio” to record everything you hear. Sharing a tab records that tab’s sound. Sharing a single window records no audio.
• Chromebook, in Chrome: share a tab for its audio, or the entire screen for system audio.
• Mac, in Chrome or Edge: share a tab to record its sound. Recent Chrome versions on recent macOS can also share system audio with the entire screen; if the checkbox doesn’t appear, share a tab instead. macOS also needs Screen Recording turned on for the browser in System Settings › Privacy & Security, followed by a browser restart.
• Safari and Firefox: screen and window recording with your microphone works, but neither browser can capture system or tab audio.
• Linux: Chrome can share tab audio. Whether system audio is available depends on your desktop and browser version.

Anything you can see on screen or hear from your computer, within the audio limits above. Some common uses:

• Tutorials and walkthroughs: show how to use an app, with your voice and, if you like, your face in a corner.
• Bug reports: capture the exact steps that break something, press Alt + Shift + S for a screenshot of the error, then cut the clip down or save a short GIF for the ticket.
• Presentations: talk through your slides once so people can watch when it suits them.
• Design and code feedback: walk through a mockup, a pull request or a document instead of writing a long message.
• Short clips for social media: record just the area that matters, then save it at 9:16, 1:1 or 4:5 on a background, zooming in where the detail is small.
• Online meetings: record a call running in a browser tab, including the other participants’ audio. Tell everyone and get their consent first. In many places recording a conversation without it is against the law.

When you press Stop, the recording opens with a preview. Open Edit to change it before you save. Cuts, style, zoom and size are rendered together into one new copy, so the video is re-encoded only once, and the original recording isn’t changed. All of it happens on your computer.

• Cut: select a section on the timeline and cut it out, or keep only the selection and drop everything around it. Each cut is listed so you can take it back, and Undo reverses your last change.
• Remove pauses: the editor looks through the sound for silences of about 1.2 seconds or longer and adds each one as a cut you can check.
• Markers: moments you flagged while recording show on the timeline, so you can jump to the part you meant to fix.
• Make it smaller: fit the file under 25 MB or 10 MB, scale it to 720p or 480p, or type a size in MB. Size targets are a best effort; very busy footage, such as fast scrolling or video, can land slightly above a small target.
• Style: a gradient or solid background, padding, rounded corners and a shadow, at 16:9, 1:1, 9:16 or 4:5 for social media.
• Zoom: pick an area and the moments to zoom in on it. The view moves in and out smoothly.
• Share…: where your system supports it, the file goes straight to Mail, Messages, AirDrop and similar apps. Many desktop browsers don’t offer sharing; Save always works.

The recorder works in current desktop Chrome, Edge, Safari and Firefox. Chrome and Edge get every feature.

Phones and tablets are different. iPhone, iPad and Android browsers give web pages no way to capture the screen, so there the recorder offers Camera only and Audio only, and points you to the phone’s own recorder: Control Center on iOS, Quick Settings on Android.

MP4, with H.264 video and AAC audio, is the safe choice. It plays on Windows, macOS, iPhone and Android, and opens in almost every video editor and slide app. Current Chrome, Edge and Safari record MP4 directly, so there’s no conversion step.

Firefox records WebM, with VP9 or VP8 video and Opus audio. WebM plays in every modern browser, but some desktop players and editors are fussier about it. If your browser supports WebCodecs video encoding, one click converts WebM to MP4, or MP4 to WebM, on your own computer.

Audio-only recordings save as M4A (AAC) or WebM (Opus). Files are named with the date and time, such as screen-recording-2026-09-28-14-05.mp4. Chrome and Edge let you choose the folder in a “Save as” dialog; other browsers put the file in your downloads.

These work while the recorder page is in focus. When you’re in another app, use the floating mini controls in Chrome and Edge, which have buttons for all of these, including a flag for markers and a camera for screenshots. You can also glance at the browser tab, whose title reads “● REC 02:14” while you record.
