    What a .ts file is

    A .ts file is an MPEG transport stream: a format designed to deliver video over broadcast and network connections, where data can arrive damaged or out of order. It’s built from small packets that a player can pick up mid-stream, which is perfect for live TV and streaming but awkward for saved files. Players may not know the total length, seeking can be slow, and many editors won’t import TS at all.

    Common sources are saved HLS web streams (the format behind most live streaming), screen recorders set to TS output, and IPTV or set-top box recordings.

    How to use it

    1. Choose your .ts files or drop them on the box above.
    2. H.264 streams are rewrapped in seconds; other video formats are re-encoded and show a percentage.
    3. Download the MP4.

    Which TS files convert

    Inside the TS Result
    H.264 video, AAC audio (web streams, most recorders) Copied: fast and lossless
    HEVC video Re-encoded to H.264
    MP3 audio Converted to AAC
    MPEG-2 video (older TV broadcasts) Can’t be decoded in a browser
    Dolby Digital or MP2 audio (TV broadcasts) Usually can’t be decoded: no sound

    The note under each result says whether the video was copied or re-encoded and warns if the sound couldn’t be converted, so you’ll know straight away.

    Joining several TS segments

    Streams are sometimes saved as many short numbered .ts segments. This converter handles one file at a time and doesn’t join segments. If you have the full stream as a single .ts file, convert that instead.

    Privacy

    The file is converted inside your browser using Mediabunny, an open-source media library, and your browser’s own video tools. Nothing is uploaded.

    Questions

    Why convert TS to MP4 if the TS already plays?

    Transport streams are designed for broadcasting and live streaming, not for storing. Many apps can't seek through a TS properly, show the wrong length, or won't import it at all. MP4 has an index, so players jump to any point instantly and editors accept it.

    My TV or satellite recording won't convert. Why?

    Broadcast recordings often use MPEG-2 video or MP2 and Dolby Digital audio. Browsers can't decode those formats, so the converter shows an error or a no-sound note. A desktop app such as HandBrake or VLC can convert those.

    Does it work with camcorder .MTS or .M2TS files?

    Not reliably, so they aren't accepted here. Camcorder files use a variant of the transport stream format, and their audio is usually Dolby Digital, which browsers can't decode.

    Is quality lost?

    Not for H.264 video with AAC audio, the usual combination in web streams and modern recordings. Those streams are copied into the MP4 unchanged.
