ClipSave 作成者: SAHEDUl ISLAM RONY

Save videos and audio from YouTube and 1000+ other sites, right from Firefox. Free, open source and private: no account, no ads, no analytics, no servers.

What it does
- Click the toolbar button on a video page: ClipSave lists every quality with its file size. Pick Video or Audio, choose a quality, and click Download.
- Save MP4 video, or MP3 / M4A audio. 1080p and up are tagged HD, 2160p 4K.
- Whole playlists: pick a quality and which videos, name the folder, and number the files 1 → N or N → 1. Each playlist gets its own folder.
- Rename a file before saving. ClipSave never overwrites one: a second "Song" becomes "Song (2)".
- Right-click a page or link: ClipSave → Save video / Save audio.
- Downloads keep going with the popup closed. Cancel, retry, or show the file in its folder.
- Settings: choose separate folders for video and audio, light or dark theme, and one-click updates.

One-time setup
ClipSave uses a small free, open-source helper app that runs yt-dlp on your computer, because browser extensions aren't allowed to run download tools. The first time you click the button, ClipSave shows one command to paste into Terminal (macOS, Linux) or PowerShell (Windows). The helper brings everything it needs, and ClipSave carries on by itself once it's installed.

Works on macOS, Windows and Linux.

Private
Everything runs on your computer. Nothing about you or what you save is sent anywhere.

Please save responsibly
Only save videos you have the right to keep: your own uploads, public-domain and Creative Commons works, or videos a site lets you download. Respect copyright and each site's terms.
