Support & FAQ

M3U8to is a free online tool that converts m3u8 (HLS) streams into a single MP4 file — directly inside your browser. Paste an m3u8 URL, and the tool fetches the playlist, downloads the video segments, and merges them into one ready-to-save MP4 without uploading anything to a server.

Any website that serves video over the HLS protocol works, because processing happens in your own browser rather than on our servers. Typical sources include live-stream platforms, IPTV endpoints, CDN-hosted .m3u8 playlists, and many news or education sites. If a stream plays in your browser, there is a good chance M3U8to can convert it.

Note that streams protected by DRM or requiring a login token you do not provide cannot be processed.

Yes. All conversion and download features on m3u8to.com are completely free, with no registration, no login, no watermarks, and no limits on the number of conversions.

All video processing happens locally on your device — your browser downloads the segments and merges them into MP4 without any data passing through our servers.

No video content is stored on our servers. We do not track or analyze your downloads, and no account or personal information is required.

No. M3U8to runs entirely in your browser — there is nothing to install, no extension required, and no desktop app. Open the page, paste your m3u8 URL, and convert. A modern browser (Chrome, Edge, Firefox, or Safari) is all you need.

M3U8to outputs MP4, the most widely compatible video format, so files play on virtually every device and player. The input side supports HLS playlists (.m3u8) carrying MPEG-TS or fMP4 segments.

M3U8to is designed for saving videos for personal use only. You are responsible for complying with the terms of service of the websites you download from and for respecting copyright laws. We recommend only downloading content you have permission to save.

The most common causes are: the link has expired (many m3u8 URLs are time-limited tokens), the stream requires login cookies or DRM keys your browser cannot access, the playlist is geo-blocked for your network, or the URL points to a master playlist whose variants your browser cannot fetch. Try re-copying a fresh link, playing the video once before converting, or testing on a different network.

You can open M3U8to in several browser tabs and run conversions in parallel, since each conversion is fully local to your own browser. There is no queue or server-side batching — your device handles the merging work, so very large streams may take a while depending on your hardware.
