6 Quick Solutions to Download Blob Videos (Tested)

2020-01-21 03:28:33 / Posted by Peter William to Video Follow @ Peter

Since HTML5 offers the video tag, it has become simple to play a video on a webpage (just set the "src" attribute to the address of the video). "src" points to the real video link, once you got the link, you can directly download the video without any hassle. To prevent video download, some websites use a blob URL to encrypt the video link. So how to download blob videos? In this post, we will walk you through several solutions about blob video download as fast as possible.

Facts You Need to Know about Blob Video

What is Blob Video?

When you use a crawler to crawl some videos or search for "src" of a video tag on Vimeo, Dailymotion, Twitter, YouTube, Facebook, etc., you might find blob video URLs in Inspect Element. These URLs can't be opened and return "404", "Your file was not found", or other errors.

Blob: https is not a protocol, but a string of tags generated by the blob object in HTML5. The browser will parse the data contained in the blob object internally.

How to Find a Blob URL?

  1. Open a blob video.
  2. Right-click the page.
  3. Choose "Inspect".
  4. In the "Element" tab, Ctrl + F and search the keyword "blob".

Can I Still Download Blob Video Free from Inspect?

It depends on website codes. Some websites support blob video download, others may not.

The most common way recommended in the forum: open a blob video > go to "Inspect" > "Network" tab > download video in .m3u8 or .ts format.

However, I don’t think it’s a good way to download blob videos from “Inspect":

  1. Blob videos on different websites have different codes. You need to spend a lot of time studying them separately.
  2. The codes of blob videos are keeping updating, hence the solution doesn’t always work.
  3. A bit complicated for non-programmers.
  4. The blob videos in “Inspect” are broken down into many small clips in .m3u8 or .ts format, which are not easy to play.

How to Download Blob Videos on Mac/Windows via URLs?

Each blob video has both a blob URL and a normal URL. For example:

  • Blob URL: blob:https://vimeo.com/f2131345-fac6-4ec4-8038-4dc5ed27b2ff
  • Normal URL: https://vimeo.com/42196073


  • Blob URL: blob:https://twitter.com/d87042a5-5107-4bee-b796-ca683311fae6
  • Normal URL: https://twitter.com/MountainButorac/status/844505243538931714

  • Blob URL: blob:https://www.dailymotion.com/8e6f41ff-830d-4f3d-8562-64f53e3148b3
  • Normal URL: https://www.dailymotion.com/video/x7b56dr
