How to download a "blob:" video in Chrome

2 min read · Works in Chrome

Quick answer

A blob: address only lives inside the page, so you can't save it directly. Open FileSnatch while the video plays: it finds the stream behind the blob and saves it as a normal MP4.

The problem

Right-click on many videos shows an address like blob:https://… and "Save video as" is missing or saves nothing. That's because the page builds the video on the fly from a stream (usually HLS or DASH); the blob address is only a temporary handle inside that tab.

    Open the page and let the video play for a moment.

Questions

Why can't I just open the blob link?

It only exists inside that tab; it isn't a file on a server.

Does it work for DRM videos?

No. Encrypted streams (Netflix and similar) can't be saved.
