Convert m3u8 to MP4 and More
Automatically convert HLS streams into MP4, MKV, or MOV. All processing runs locally in your browser — no uploads, no waiting.

Every input format converts to any output format.
How Conversion Works
From stream detection to a playable file — all inside your browser.
Detect
The extension finds the video stream on the page — HLS, DASH, or direct file. It identifies resolution and codec automatically.
Convert
WebAssembly remuxes the stream into your chosen format — MP4, MKV, MOV, or WebM. Zero re-encoding, zero quality loss.
Download
Your ready-to-play MP4 (or MKV, MOV, WebM) downloads instantly. Open it in any video player on any device.
Why This Converter Is Different
No external tools, no quality loss, no uploads.
No Extra Software
Other tools make you download raw HLS segments and stitch them with FFmpeg. Video Downloader Plus does the conversion automatically inside your browser — one click, done.
Multiple Output Formats
Choose between MP4, MKV, MOV, or WebM depending on your needs. MP4 is free for everyone — premium unlocks MKV, MOV, and WebM.
Zero Quality Loss
The converter uses remuxing — repackaging the original data into a new container without re-encoding. Your video stays pixel-perfect, exactly as the source.
100% Private
All processing runs locally via WebAssembly. Your video data never leaves your machine. No uploads, no cloud servers, no third-party access.
Everything runs in your browser
Powered by WebAssembly, the converter processes video locally on your machine. No data is uploaded to any server. Your videos stay private — always.
