Mass Downloader

Download videos with the Mass Downloader desktop app: full video or only the part you select. (YouTube is not supported.)

Mass Downloader puts a download button on video players, so you can save a video with one click — or only the part you need. HOW IT WORKS • Open a page with a video and click the red MASS DOWNLOADER button on the player. • Choose a format: best quality, 1080p, 720p, 480p, 360p, or audio only (MP3 / M4A). • Dubbing: when a video has its sound in several languages, pick the one you want. • Full video, or Clip part: set Start and End (or drag the handles) and download just that part. • The download is made by the Mass Downloader desktop app on your own computer. REQUIRES THE DESKTOP APP This extension is the browser button for the Mass Downloader app for Windows. Install the app from https://massdownloader.automatflows.com and keep it open while you download. The extension talks only to the app on your own computer (127.0.0.1). PRIVACY • No account, no tracking, no ads. • The extension does not collect or send your data to us or anyone else. When you click download, the video page address and your chosen format go only to the app on your own PC. • It stores only your settings (default quality, button position) in your browser. Please download only videos you own or have permission to download, and respect each website's terms. YouTube is not supported.
