What are Blob URLs?

Blob URLs are pseudo protocols that assign temporary URLs to media files. This process is crucial because most websites cannot process the raw data contained by files. They require data in the form of binary code that loads through the blob URL. In simpler terms, the blob URL provides data and acts as a fake source for the files on a website.

The blob URL addresses can be found in the DevTools of the webpage. These links, however, cannot be accessed because their source page does not exist. Nevertheless, there are a few different ways through which you can download a blob URL video.

  1. Not working on pages that detect opening of the dev tools and simply cutoff the stream. Which is becoming more and more common. Even detaching the dev tools window from the browser window doesn’t fool them. Your network will not show any code that you could search through for m3u8 or anything because by then the stream connection already got terminated.
