Questions
Is it free?
Yes, completely, and the source code is open (MIT licence). There is no paid tier and no account.
Will it save any video on any site?
It saves what a page plays in your browser, in the formats listed above. It does not bypass DRM, logins or paywalls, and some players simply never expose a stream. When something cannot be saved, the card tells you why.
Why does it ask for access to a site?
Reading a page you are on needs nothing. Fetching a stream from another server, or looking into a player embedded from another site, needs that site's permission — asked when you press the button, revocable in Settings.
Does it reduce the quality?
No. Video is never re-encoded: segments are joined as they are. Only audio is converted, and only if you ask for MP3, M4A, AAC or WAV.
Where do the files go?
Into Chrome's own Downloads folder, through Chrome's download manager. You can pick a sub-folder or be asked every time.
Does it send anything anywhere?
No. No analytics, no telemetry, no remote code. The only requests it makes are the ones that fetch the media you asked for.
Which browsers does it support?
Google Chrome 116 or newer.
