This article will show you how to download blob video in 4 different ways. Here’s a common scenario. You are trying to save a video from a website. However, there isn’t a download option. When you right-click and select Save As, it won’t save the video. You use Chrome DevTools in the hope of finding the source address through which it may be possible to download the video. Finally you find this: src=”blob:https://www.example.com/xxx”. When you open the blob URL, you will get the Page Not Found error or alike. How do you download a blob video? Please read on.

This part will show you how to save blob video with utmost ease and best quality.

Before getting started, let’s learn a little bit about blob (Binary Large Object) videos. There are different ways to save files such as videos uploaded to a server. One can store videos in a file system. One can also choose to save videos as blobs in a database. The two methods have their pros and cons. For example, the latter can offer more security. A blob represents bytes that contain the data of a file. You can consider a blob URL a pointer to a blob.

You can find blob videos on websites such as Twitter, Vimeo, YouTube and Facebook. Open a Facebook video on Chrome. Right-click and select Inspect. You need to bring up the search field if you don’t find one. Now search for blob. You should find the blob URL, as shown in the screenshot.

Here’s a tip, which may be useful regardless of the operating system you are using.

As you can see, it’s very easy to download blob videos from popular video-sharing websites and social media platforms. When it comes to a few certain websites, things can be a bit complicated. Downloading through the regular video URL may not work. The good news is that there is an easy workaround.

Step 1. Play the blob video in Chrome. Right-click and choose Inspect.

Note: If you use a different web browser such as Safari, the steps will basically be the same, with only slight difference.

Step 2. Go to the Network tab and select All. Find the Filter field and enter m3u8 in the field. By placing your mouse over the result, you will see an URL with the ending .m3u8.

Step 3. Right-click the result and choose Copy > Copy link address.

FastestTube offers a blob video downloader extension for Safari. However, it is not supported by the current Safari. To make it work, one needs to downgrade Safari, which seems not worth it. Mac users can use the first app that I recommend in the article.

Download video from blob URL online

Applies to: macOS, Windows

There are lots of web-based tools designed to download videos including blob videos from websites like Facebook, YouTube and Twitter. The advantage is that you don’t need to download and install anything.

However, there can be a few disadvantages at least with some of such tools. I have tested several popular online blob video downloaders and found some shared downsides. One may overcome the last two issues by using an ad blocker.

  • Limited supported websites
  • Annoying or potentially malicious ads
  • Clicking the download button or a similar button will take you to an irrelevant (unwanted) website

That being said, there are still some decent blob video downloaders online. Below is how to download blob video using this method.

Step 1. Copy a regular video URL.

Step 2. Visit https://en.savefrom.net/. Paste the link in the URL box.

Step 3. Click the Download button, which will bring up a new Download button.

Step 4. Click the dropdown list to choose a resolution option such as MP4 1080p.
