About Alt Video Downloader

When you find a video on Alt that you want to keep, there is no need to copy links or switch to another service. The extension works from the same page you are already viewing, keeping the process simple and contained.

Just let the video load and begin playing. Then open the extension, and it will find compatible video sources made available by the page. You can pick the format you prefer and save the file straight to your device.

The download happens through your desktop browser's built-in save mechanism. The saved file is automatically named using the Alt page title, making it easy to identify later. This straightforward approach keeps your offline library organized without extra steps.
