Frequently asked questions
Is there a time limit?
No fixed limit. Recordings are kept in memory until you download them, so very long recordings at high resolution can use a lot of memory; an hour at 1080p is usually fine on a computer.
Why is there no system sound?
Browsers only share audio from a browser tab, and on Windows from the whole screen. On macOS, sound from other apps is not available to browsers. Choose a tab and tick Share audio in the dialog.
Why WebM and not MP4?
Most browsers record natively in WebM. Use the MP4 option to convert it in the browser when you need MP4 for editing or sharing.
Can I record on my phone?
Mobile browsers do not allow screen capture. Use your phone's built-in screen recorder, then edit the video with these tools.
Is my recording uploaded?
No. It is created and stored in your browser, and only saved when you download it.
Is there a watermark?
No. Recordings are clean.
Can I trim the start and end?
Yes. Download it, then open it in Trim Video to cut off the first and last seconds.
