Download video from any website
Not a list of supported sites. If the page plays it, the extension sees it — because it works on the traffic, not on a catalogue of platforms.
Why "supported sites" lists exist, and why this has none
Most tools keep a catalogue: they learn how each platform serves its video and break when that platform changes something. The extension works one level below, on what the browser is actually receiving. A site it has never seen behaves like any other, because the mechanism is the same.
Pages with no download button
The absence of a button is a decision by whoever published the page, not a technical barrier. The video is already arriving at your browser or you would not be watching it. What the extension does is let you keep the copy that is already there.
Embedded players
A large share of video on the web is not hosted where you are watching it: a blog embedding Vimeo, a course embedding Wistia, a news site embedding JW Player. What gets detected is the player, so the domain in the address bar is irrelevant.
Video split into segments (HLS, DASH and blob)
Modern streaming does not send one file: it sends hundreds of fragments the player stitches together, which is why right-click gives you nothing and why the URL starts with blob:. The extension collects the fragments and joins them into a single MP4 without re-encoding.
Everything on the page, not just the video
The same panel lists audio, images and documents the page is loading, each with its size. Useful when what you came for is the PDF behind a viewer or the images of a gallery, not the video.
What it does not do
It does not bypass DRM, it does not open what your account cannot open, and it does not get into private content. If the page does not play it for you, there is nothing to capture.
Frequently asked questions
Which sites does it support?
There is no list. It works on what the browser receives, so a site it has never seen behaves like any other.
The page has no download button. Does it work?
Yes. The absence of a button is an editorial decision, not a technical barrier.
What about a blob: URL?
That is streaming split into fragments. The extension collects them and joins them into one MP4 without re-encoding.
Does it work with embedded players?
Yes, because what is detected is the player, not the domain you are on.
Does it get past DRM?
No. Protected content stays protected.
Can I download images and PDFs too?
Yes. The panel lists everything the page loads, with sizes.
