The internet overflows with videos of every kind. From YouTube to TikTok, Instagram, Facebook, and X (formerly Twitter), the sheer volume of content is staggering. Each platform offers a unique universe filled with enriching tutorials, creative sequences, personal moments, and lively discussions. Faced with such abundance, you’ve likely wanted to save some of these videos to your device for offline viewing or archival purposes. For that, we have just the tool you need: Cobalt.tools! This online tool has been specifically designed to facilitate the downloading of your favorite videos, regardless of their origin on the web.

Cobalt.tools: Your Swiss Army Knife for Video and Audio Downloads
Cobalt.tools is a free and open-source online tool that allows you to download videos from a wide range of popular platforms, including YouTube, X (Twitter), TikTok, Instagram, Dailymotion, Reddit, and many more. Find the complete list of supported sites on the project’s GitHub page.
With Cobalt.tools, several download options are available to you. You can choose the format, but also the quality of your videos, ranging from the practical 360p to the spectacular 8K, passing through the intermediate 480p, 720p, 1080p, 1440p, and 4K resolutions.

Cobalt.tools also allows you to download videos in MP3, OGG, WAV, or OPUS formats for those who prefer to keep only the audio track. To configure all of this, go to the tool’s settings (the “Settings” button).

A Tool That Respects Your Privacy
Indeed, the tool also distinguishes itself by its commitment to the confidentiality and security of its users. First of all, no advertising is present on the site, allowing you to navigate and download your favorite content without interruption or distraction.
In addition, Cobalt.tools does not collect any data about you, not even your IP address. The only information that the developer of Cobalt.tools collects is the number of users who visit and use the site. That’s it!
Finally, note that if your download involves specific processing or rendering, Cobalt.tools takes additional measures to secure the data related to the requested content. This data is encrypted and stored temporarily in the server’s RAM before being permanently deleted within 90 seconds. This ensures that no residue of your download activities remains on the server.

Using Cobalt.tools is very simple. Whether you are using a computer (Windows, macOS, or Linux), a smartphone, or a tablet (Android or iOS), the procedure to download a video from the web is exactly the same. Here’s how to do it.
- Start by copying the URL of the video or content that you want to download from the address bar of your web browser.
- Then go to the official Cobalt.tools website.
- Paste the URL into the field provided for this purpose, and then select “Auto” or “Audio”, depending on the format you want.
