Is TS to MP4 lossless?

Usually. H.264 video and AAC audio are copied, so the conversion is fast and the quality is unchanged.

Why convert TS to MP4?

TS is made for broadcasting and streaming. MP4 is smaller to store, seeks reliably, and opens in phones, editors, and social apps.

How to convert TS to MP4 online

Open an MPEG transport stream (.ts), such as a TV or OBS recording or a downloaded HLS stream, and export an MP4. The TS to MP4 converter copies H.264 or HEVC video and AAC audio into MP4 without re-encoding, in your browser.

Pick a file or drop it into the converter above.

What to expect

Supported inputs: MPEG-TS (.ts, .mts, .m2ts) files and other readable video files.
What happens: H.264, HEVC, and AAC tracks are copied into MP4 unchanged. Dolby Digital audio is re-encoded so browsers can play it.
Limits: MPEG-2 video, common in older TV recordings, can't be read yet. Only one TS file converts at a time; join segments with Combine videos.
