About this tool
Records your screen (a tab, window, or entire display) directly in your browser, with optional microphone and tab/system audio. When you click "Stop Recording," the recording is saved to this browser's local storage (IndexedDB) — not uploaded anywhere — so it's still there if you refresh the page or come back later, ready to preview and download as a .webm file.
Refreshing or closing the tab while actively recording will discard that in-progress recording — browsers don't allow JavaScript to survive a page reload, so this can't be fully prevented. This tool warns you before you leave the page if a recording is running. Once you click "Stop," the recording is saved and safe from refreshes.
Frequently asked questions
- Where are my recordings stored?
- Entirely in your browser, using IndexedDB — the same kind of on-device storage local apps use. Nothing is uploaded to any server. Because it's tied to this specific browser and device, recordings won't appear if you switch browsers or devices, and clearing your browser's site data will delete them.
- Why is there no system/tab audio in my recording?
- The most common cause: the checkbox for this lives in your browser's own share picker, not on this page, and it defaults to off — look for "Share audio" (or "Share tab audio") near the bottom of the picker and tick it before confirming. It also only works when sharing your Entire Screen or a Chrome Tab — Chrome does not support system audio when sharing a single Window. On top of that, macOS blocks system audio capture almost entirely regardless of browser, and Safari/Firefox support is limited or absent. If it's still missing after all that, this tool will show a warning after you start recording. Microphone audio isn't affected by any of this — it works anywhere your browser allows mic access.
- What format are recordings saved in?
- WebM (VP9 or VP8 video with Opus audio) — the format browsers natively record to. It plays in most modern browsers and media players; convert it elsewhere if you specifically need MP4.
- Is there a size or time limit?
- No fixed limit from this tool, but your browser's storage quota is finite — long recordings use real disk space. Download and delete recordings you don't need anymore to free up room.
