About MPEG Transport Stream (TS)
An MPEG transport stream (TS, MTS, M2TS) is the container used for digital TV broadcasting and Blu-ray. It is built from small fixed-size packets that tolerate transmission errors.
TV recordings, AVCHD camcorder files (.mts), Blu-ray discs (.m2ts) and HLS streaming segments.
The packet structure adds overhead, and many editors and phones do not open TS files directly.
Convert TS to MKV online free, no account required — MKV is a flexible open container for video with any number of audio and subtitle tracks.
Change TS to MKV without losing quality — convert TS to MKV free in your browser.
Why won't my media player open the .ts file I recorded? A transport stream is written for broadcast, so many players expect a renamed or converted container before they accept it.
About Matroska (MKV)
Matroska (MKV) is an open container format that can hold almost any video and audio codec, any number of audio and subtitle tracks, chapters and attachments.
It is popular for films and series with several audio languages and subtitle tracks, and for archiving video.
Many phones, browsers and TVs do not play MKV files directly, even when they support the codecs inside.
Why convert video to MKV? When one file must carry several audio languages, subtitle tracks and chapters, no container holds them as flexibly.
What changes when you convert TS to MKV
- The TS is re-encoded into MKV at the default quality settings, so the result looks close to the original but is not bit-identical.

Before you convert TS to MKV, you can adjust: Video codec, Rate control, Quality (CRF), Video bitrate, Resolution, Width, Height, Scale fit, Frame rate, Encoder preset, Audio codec, Audio bitrate, Trim start, Trim duration, and Remove metadata.

Each plan sets a maximum file size and a number of conversions per day, and video and audio files also have a maximum length. Guests can convert files up to 100 megabytes and 5 per day; a free account raises this to 500 megabytes and 25 per day; paid plans go up to 100 gigabytes.
Your converted MKV file is kept for 2 hours, then deleted.
