KlipVault Video Downloader — Velocity Extensions

KlipVault Video Downloader

Companion browser extension for KlipVault (https://klipvault.xyz/). Download videos from popular streaming sites using the open-source yt-dlp engine. Enables HLS stream downloads, batch processing, and automatic cookie extraction for authenticated content.

What is KlipVault?

KlipVault is a free online video downloader. Visit https://klipvault.xyz/, paste a video link, and get direct download URLs in seconds. The website handles the interface; this companion extension handles the actual downloading by running yt-dlp locally on your computer.

Why this extension?

Server-based video downloaders are aggressively blocked by streaming platforms. By moving the download engine to your local machine via yt-dlp, KlipVault bypasses these restrictions completely while keeping your data private — no video content ever touches our servers.

Key Features:

• HLS Stream Downloads — Download livestream replays and segmented video (.m3u8) that browser-only tools cannot handle
• Automatic Cookie Extraction — For platforms requiring login, the extension extracts your session cookies directly from the browser so yt-dlp can access the content
• Batch & Playlist Downloads — Queue multiple videos or entire playlists
• Quality Selection — Choose from available formats: MP4, WebM, MP3, M4A
• No Watermarks — Clean, original-quality downloads
• Dark Mode — Matches your browser preference automatically

How it works:

1. Visit https://klipvault.xyz/ and paste a video URL
2. The website fetches metadata (title, thumbnail, available formats)
3. Select your preferred format and click "Download via Extension"
4. The extension auto-extracts any needed cookies and passes the URL to yt-dlp
5. yt-dlp downloads the video directly to your computer's Downloads folder

Requirements:

• yt-dlp must be installed on your computer. Get it at https://github.com/yt-dlp/yt-dlp or run pip install yt-dlp (1/2)
