M3U8 to MP4 / Video Converter

Convert any M3U8 stream to MP4, MKV, AVI right in your browser

Your browser doesn't support SharedArrayBuffer. Only MP4 remux will be available (no re-encoding).

Waiting to start...

Conversion happens entirely in your browser using ffmpeg.wasm — no uploads needed.

Large files (>500MB) may take longer. Enable Large File Mode for better stability.

Some formats may not be supported on all browsers. MP4 is recommended for maximum compatibility.

All conversion happens locally with ffmpeg.wasm — your video never leaves your device.

Convert to MP4, MKV, AVI, MOV and other formats supported by ffmpeg.

Chunked processing mode handles streams over 500MB without crashing.

How It Works

Paste the M3U8 URL and choose format & quality

Segments are fetched and loaded into ffmpeg.wasm

ffmpeg converts and outputs your chosen format file

ffmpeg.wasm runs in your browser which is slower than native. For large files, enable Large File Mode and be patient — quality conversion takes time.

It processes the stream in smaller chunks to avoid browser memory limits. Recommended for streams over 500MB.

Currently we support video format conversion only. Audio extraction may be added in future updates.
