Downloading videos can be a pain, especially when the website we use doesn't want to make it easy. To prevent people from uploading their videos, some websites even use a large binary object, or "blob", to encrypt them. Blobs are used to store a specific type of information, such as images and media files. They also generally require much more space than other data types.


Blob URLs contain pseudo-protocols that can create a temporary URL to audio and video files. This type of URL basically acts as a fake source for the media on the website, so you cannot download it directly.


Instead, you should use third-party conversion tools. However, you first need to find the blob URL itself. Here is a complete guide on how this process works:

How to download a video from a blob?

Before knowing what software you can use to convert blob URLs to videos and download them to your device, you need to know how to find the blob URL address.

You will need to access DevTools on the web page that contains the video you want to download. Here are the steps:

  1. Right-click on the web page and click "Inspect" from the menu.
  2. When the DevTools panel opens, click on the three vertical dots in the upper right corner and select "Disconnect in separate window".
  3. Press Ctrl + F on Windows or Cmd + F on Mac devices to find the blob URL.
  4. Enter “blob:HTTP” to find the video link.
  5. Now click on the "Network" tab in the DevTools dock.
  6. Search for "m3u8" (which is the video extension you need).
  7. Click the link and be sure to copy the request URL from the page.

Remember that you cannot open this link from a web browser because the source page does not exist. To get the video, you will need to use a converter.



This media player might not be the most popular video software nowadays, but it still has some great useful features.

For example, it can convert blob URLs to MP4 files, which you can save on your computer. So, make sure to install the latest version of VLC player, then follow these steps:

  1. Launch VLC player on your computer.
  2. Click "Media" in the toolbar at the top.
  3. From the drop-down menu, select "Open Network Stream".
  4. When a new window opens, paste the copied blob URL into the space under "Please enter a network URL".
  5. Click the down arrow next to the "Play" button.
  6. From the drop-down menu, select "Convert".
  7. When the conversion window appears, select the output quality and destination file folder.
  8. Finally, click on the “Start” button.

When VLC media players convert the blob URL to MP4, you can find the video in the destination folder.

If you are a Mac user and don't have VLC (or don't want to download it), you can try another solution. Cisdem Video Converter is a very efficient conversion utility with many notable features, and one of them is blob URL download. If you are not already using it, make sure to install Cisdem on your Mac computer first. Then follow these steps:

  1. Open Cisdem on your Mac PC. The converter page opens by default.
  2. Click the "Download" button to enter the download page.
  3. Paste the blob URL in the available field and click the upload button.

All you have to do is locate the stored video to verify that the process worked.



Maybe the idea of ​​installing third-party software doesn't appeal to you. If you don't use your personal computer or don't want to use storage, you can use a web-based download tool instead.

SaveFrom.net can convert videos from various sites containing media files and download them in different output formats. Here's how to save your blob video with this efficient tool:

  1. Go to the SaveFrom.net page and paste the blob URL into the designated field.
  2. The website will display a video thumbnail and you can choose the video quality you want.
  3. Then select the "Download" button.
  4. You will be prompted to save the file to a specific location.

It takes a few moments to download, but then you can find your video in the saved location. Using SaveFrom.net is quite convenient, but keep in mind that you will encounter annoying ads and there is no way to download 4K blob videos with this tool.


Moreover, the number of available output formats is limited compared to the installed video converter and downloader software.

Always have access to your favorite videos

By using one of the blob url download methods above, you can save videos from Facebook, Twitter and many other websites. It's a great way to download YouTube videos and watch them offline as well.

Finding the blob URL on the page that contains the video is the first step. With just a few clicks, you can copy the URL and use it to download that video using one of the many free tools available.

Then you have to decide whether to install VLC media player, Cisdem (if you are a Mac user) or use a web tool like SaveFrom.net. Each has its advantages and disadvantages, and it's up to you to find the one that suits you best.
