简介
Save the videos and audio you're allowed to keep, straight from the page you're watching.
Play a video, click the extension, and download it. The icon shows how many files it found on the page.
What it does
• Finds video and audio files (MP4, WebM, MP3, M4A and more) and HLS streams on the page you're viewing
• Lets you pick the quality of HLS streams, and saves them as MP4, merging separate audio tracks
• Handles AES-128 encrypted HLS streams
• Shows progress and speed; pause, resume, cancel and retry downloads
• Keeps a download history, with "Show in folder"
• Names files the way you want, using the page title, site, quality and date
• Light and dark themes
What it doesn't do
• It doesn't work on YouTube.
• It doesn't download DRM-protected content (for example Netflix, Prime Video, Disney+, JioHotstar or Spotify), and it never tries to get around DRM. When a page plays protected video, the extension tells you so.
• Live streams aren't supported yet.
Private by design
Everything happens in your browser. The extension has no servers, no analytics and no tracking, and nothing about the pages you visit or what you download is sent anywhere.
Please only download content you own, have permission to download, or that is licensed for downloading.
