M3U8 Tools

About

M3U8 Tools runs media processing in your browser with Mediabunny and WebCodecs. Files are not uploaded to our servers.

Local-first

Conversion, trimming, and packaging happen on your device. There is no account and no watermark.

CORS limits

Public M3U8 URLs must allow cross-origin requests from this site. If a fetch fails, download the playlist and segments yourself, or host a CORS-enabled source and try again. v1 does not ship a proxy.

Browser support

Tools that encode or decode video need WebCodecs (best on Chrome and Edge). Probe and some remux paths may still work without it.

Responsible use

Only process media you have the right to access and redistribute. Do not use these tools to infringe copyright or bypass access controls.
