What is Screen Recorder?

Screen Recorder is a free, browser-based screen capture tool. Click Start, pick your screen, a window, or a tab in your browser's own sharing prompt, and record — with your microphone, your webcam as a picture-in-picture overlay, both, or neither, entirely your choice. It's a dedicated tool for creating a new recording, separate from Video Editor, which is for editing existing video — the two stay connected through a one-click "Open in Video Editor" handoff once you're done recording.

What can Screen Recorder do?

Screen, window, or tab capture — your browser's own screen-sharing prompt lets you pick exactly what to record.
Optional microphone — narrate over your recording, on by default with a genuine off switch. Mixed together with any system/tab audio your browser shares, so both survive in the final recording.
Enhance voice — an optional checkbox (when the microphone is on) that reduces hum/buzz and low rumble on your mic input in real time as you record, for clearer narration in noisy rooms.
Optional webcam picture-in-picture — show your face in a movable, resizable corner box over the screen recording, or leave it off entirely for a screen-only capture.
Live capture checklist — see exactly what's actually being captured (screen video, microphone, system audio, webcam) the moment recording starts, so you know immediately if something didn't come through.
Instant preview — watch the finished recording right on the page before you decide what to do with it.
Download — save the recording as a .webm file directly to your device.
Open in Video Editor — send the recording straight into Video Editor for trimming, composition, captions, and MP4 export, with no manual re-upload.

Microphone and system audio, captured independently

A browser's screen-share permission only ever grants access to system/tab audio — never your microphone, no matter what you check in the sharing picker. Screen Recorder requests your microphone completely separately (a distinct permission, a distinct on/off checkbox), then mixes the two together in real time so narrating over a recording works regardless of whether system audio sharing is even available on your platform. Leave the microphone off and share a source with no system audio and you get a genuinely silent screen recording — nothing is captured that you didn't explicitly allow.

Webcam picture-in-picture

Turning on "Include webcam" adds a second, independent camera capture, composited live onto a canvas every frame — your screen full-frame underneath, your webcam in a rounded, bordered box in whichever corner you pick, at whichever size you set with the slider. That canvas becomes the actual recorded video, which is the only way the picture-in-picture survives into a single downloadable file. Camera is completely optional and off by default — screen-only, or screen-plus-voice, recordings work exactly the same whether or not a webcam is ever involved.

From recording to editing, without leaving your browser

Once you stop recording, "Open in Video Editor" hands the finished file straight to Video Editor using a local, same-browser handoff — no upload, no manual download-then-reupload step. Video Editor picks it up the instant it loads and drops it onto the timeline as your main video, ready to trim, add a second video or webcam overlay, apply captions, and export. If you'd rather just keep the raw recording, Download saves it as a .webm file with no extra steps.

Common use cases

Tutorials and how-tos — narrate over your screen while walking through a process.
Product demos — record an app or website with your face in the corner for a personal touch.
Bug reports — capture exactly what's happening on screen to share with a teammate.
Quick explainer clips — record, then trim and export in Video Editor without leaving your browser.
Silent screen captures — record with no microphone and no camera, then add narration or captions later in Video Editor.

Supported formats

Recordings save as .webm (VP9 or VP8 video with Opus audio, whichever your browser supports). Open one in Video Editor to export it as MP4.

Privacy and temporary processing

Recording, preview, download, and the handoff to Video Editor all happen locally in your browser — your screen, microphone, and webcam are never uploaded anywhere. The "Open in Video Editor" handoff uses your browser's own local Cache Storage, not a server round trip, and clears itself out once Video Editor has picked the recording up.

Limitations

System/tab audio depends on your platform: Chrome on macOS can only capture a single browser tab's own audio this way, never your whole screen or system sound, regardless of what you check in the share picker; Windows generally supports sharing full system audio. The microphone is unaffected by this and works the same everywhere.
Webcam position is fixed once you start: the corner and size are set before recording begins and baked into the video's pixels at capture time — there's no dragging it mid-recording, and no way to move or resize it afterward.
No pause/resume: Stop ends the recording; there's no pause-and-continue within a single recording.
Browser support: requires a browser with screen-capture support (a recent Chrome or Edge); Safari and Firefox support varies.

Frequently asked questions

Is this free?

Yes — Screen Recorder is free, with no account or login required.

Does it record my microphone?

Only if you turn it on — "Include microphone" is checked by default before you start, but it's a genuine on/off choice. You can record your screen completely silently, narrate over it with your voice, or capture whatever system/tab audio your browser shares (or both at once, mixed together).

Does it show my webcam?

Only if you turn it on — camera is off by default. Check "Include webcam" and your face appears as a repositionable, resizable picture-in-picture box over the recording, with a corner picker and a size slider. Leave it unchecked to record your screen (with or without your voice) without showing yourself at all.

Can I record my screen with no camera and no voice at all?

Yes — leave both "Include microphone" and "Include webcam" unchecked and start recording. You get a silent screen-only capture, which you can narrate over later in Video Editor if you want.

Where does the webcam picture-in-picture come from technically?

Your webcam feed is composited live onto a canvas every frame — the screen share drawn full-frame, your camera drawn into a rounded, bordered box in the corner you picked — and that canvas becomes the recorded video. This is the only way the picture-in-picture survives into a single downloadable file, and it all happens locally.

Can I choose where the webcam box appears?

Yes — four corner presets (top-left, top-right, bottom-left, bottom-right) plus a size slider, set before you start recording. The position is baked into the video's pixels at capture time, so it can't be moved after you've started.

What happens after I stop recording?

You get a preview of the finished recording right in the page, with two options: Download it as a .webm file, or click "Open in Video Editor" to send it straight into Video Editor for trimming, composition, captions, and export — without a manual download-then-reupload round trip.

How does "Open in Video Editor" work without uploading my recording?

The recording is handed off entirely within your browser using the Cache Storage API — the same local mechanism Convertam already uses to send an extracted audio track from Video Studio to Audio Studio. It never touches a server; Video Editor just picks the file up the moment it loads.

Does it capture system/tab audio too?

It can, depending on your browser and OS, using your browser's own screen-sharing permission — that's separate from the microphone. On macOS, Chrome can only capture a single browser tab's own audio this way, never your whole screen or system sound; Windows generally supports sharing full system audio. If you turn on the microphone, that's captured independently and mixed in regardless of what system audio is or isn't available.

Can I record a specific window or tab instead of my whole screen?

Yes — when you click Start Recording, your browser's own screen-sharing picker lets you choose your entire screen, a specific application window, or a single browser tab.

Does Convertam store my recording?

No. Recording, preview, download, and the handoff to Video Editor all happen locally in your browser. Your screen, microphone, and webcam are never uploaded anywhere.

What format is the recording?

A .webm file (VP9 or VP8 video with Opus audio, whichever your browser supports), downloadable directly or usable straight in Video Editor, which can export it to MP4.

Can I stop the recording early?

Yes — click the in-app Stop Recording button, or use your browser's own "Stop sharing" control; either one ends the recording the same way.

Why is my recording silent even though I shared audio?

A live per-source checklist appears the moment recording starts, showing exactly what was captured (screen video, microphone, system/tab audio, webcam) — check it if something seems off. The most common cause is a browser/OS limitation on system audio sharing (see the system/tab audio question above), not a bug; turning on the microphone sidesteps that entirely.

Can I clean up my microphone audio while recording?

Yes — check "Enhance voice" next to the microphone option before you start. It reduces hum/buzz and low rumble on your mic input live, using plain signal processing (not AI), so narration sounds clearer straight out of the recording. It won't remove every kind of background noise, but it genuinely helps.
