Screen recorder

Record a screen, window or tab — with your voice over it — straight from the browser. No install, no account, no watermark, no upload.

Your browser will ask which screen, window or tab to share. Recording stays on your device.

Recording an app with floating panels (Illustrator, Photoshop)? Pick Entire screen, not a single window — detached panels live in separate windows and a window capture records them as blank.

Advanced settings (optional)
Recording options
Tab / system audio

Records the sound of the tab or screen you share (browser support varies by what you pick — tab audio works best in Chrome/Edge).

Microphone

Adds your voice on top — narrated demos and walkthroughs. Mixed with system audio automatically.

Runs in your browser. Files are never uploaded — you can go offline after the page loads.

How to use the Screen Recorder

  1. Press Start — the browser asks which screen, window or tab to share.
  2. Record with optional mic narration; pause and resume as needed.
  3. Stop, then trim the start and end or crop the frame right in the preview.
  4. Export WebM or MP4 — with a live progress bar — and pick where it saves.

Easy to use

Drop files, pick options, download. Whole folders at once, no signup, no daily limit.

Best quality

The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.

Private & secure

Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.

Your screen is nobody's business

A screen recording shows everything — tabs, notifications, file names, the email that pops up mid-demo. "Free online screen recorders" that upload your capture to their cloud (with a watermark and a 5-minute cap as the free tier) have that footage. This recorder is your own browser's capture engine with a proper interface on top: the video is encoded on your machine and exists only in the tab until you save it. No account, no length cap, no watermark — structurally, because there is no server involved.

The workflow after recording

Stop and the recording stays on screen so you can tidy it without opening another tool: drag the two handles to trim the fumbling off the start and end, or turn on crop and drag a box to keep just the part that matters. Export to WebM (instant when you haven't edited) or MP4, with a progress bar while it encodes, and on Chrome or Edge a Save to folder… button lets you choose exactly where the file lands.

Recording an app with detachable panels — Illustrator, Photoshop, DaVinci — is the one case to watch: those panels are separate windows, so a single-window capture records them as blank. Pick Entire screen in the share dialog and everything is captured. When you need more, the rest of the toolbox is here too: compress it for email, or turn the good ten seconds into a GIF for the pull request — all without the recording ever leaving your device.

Frequently asked questions

Where does the recording go?

Nowhere — that is the point. Frames are captured and encoded by your own browser (the MediaRecorder API) and the file exists only in your tab until you download it. Most “free online recorders” upload to their servers and cap or watermark the result; this one cannot even see it.

WebM or MP4?

The browser records WebM natively — it plays in every browser and imports into modern editors. Click “Convert to MP4” for messengers, PowerPoint and older players; conversion runs on FFmpeg in your browser at about the recording’s own length.

Why no tab audio on some setups?

Browser rules: Chrome and Edge can capture tab audio always and system audio when sharing the whole screen on Windows; macOS restricts system audio, and Firefox records mic only. The tool records whatever your browser allows and says so — nobody can honestly promise more.

Your files never leave your device

Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.

  • No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
  • No limits. No file-size cap, no queue, no watermark, no account.
  • Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
