Video downloader extension for Chrome

Chrome can play almost any video but not save it. The moment a video arrives as a stream — cut into segments — "save as" disappears. An extension solves exactly that, without leaving the browser.

What it adds to Chrome

It detects what the player actually requests: HLS (.m3u8) and DASH (.mpd) streams, direct MP4 files, and also images, PDFs, documents and archives present on the page.

You pick the quality before downloading, with the estimated size of each, and the final file is rebuilt as an ordinary MP4 without re-encoding: no quality loss and no long wait.

Works identically in Brave, Vivaldi and Arc

Those three use the Chrome Web Store as their extension catalogue, so it installs exactly the same way with the same features. No separate version, no different package — there is a walkthrough for the Brave video downloader extension and for Vivaldi.

It also runs on ChromeOS, where it matters most: a Chromebook cannot install desktop software, so the browser is the only route.

What the Chrome build has that others do not

Chrome has the File System Access API, which enables two things Firefox cannot do: setting a separate folder per file type (videos here, music there, images elsewhere) and writing the download straight to disk as it goes.

That second point removes the size ceiling: with no need to hold the whole file in memory, a multi-gigabyte video downloads without exhausting RAM.

You can also run it as a side panel or in its own window, so it does not close when you switch tabs mid-download.
