About converting MPEG transport stream to Matroska video

Converting .ts video to .mkv means re-encoding the picture and sound into a different container and codec family, and this page does it entirely in your browser. A .ts file is an MPEG transport stream, the packetized format built to carry television through unreliable channels like antennas, satellites, and cable. DVR recordings, IPTV captures, and HLS streaming segments all use .ts, making it one of the most common raw broadcast formats people encounter.

An .mkv file uses the Matroska container, an open format designed to hold an unlimited number of video, audio, and subtitle tracks in one file. Collectors of high-quality rips and archival copies favor .mkv because it keeps every language track, chapter marker, and font attachment together. For this route the practical draw is holds essentially any combination of codecs and track types and fully open and royalty-free specification — balanced against safari and iOS refuse the container outright, which is worth knowing before you commit a large batch.

Why convert TS to MKV?

The practical trigger for this conversion is usually a mismatch: with .ts, packet overhead runs several percent above an equivalent MP4. Switching to .mkv buys you holds essentially any combination of codecs and track types, which is why it is the better fit for archiving discs while preserving every audio track and subtitle stream. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.

01

Add your TS file

Drop one or more .ts files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.

02

Pick MKV as the output

Select .mkv in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MKV is selectable, the route is real and validated.

03

Convert on your device

Press Convert. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab.

04

Verify and download

Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MKV file. Outputs keep the original filename with the .mkv extension.

TS to MKV questions, answered

Will converting TS to MKV lose quality?

Both sides are re-encoded, so expect a small generation loss controlled by the quality setting: ts is container-oriented and mkv is container-oriented. For visually or audibly transparent results keep quality high; for smaller files lower it and compare.

Is it private to convert TS files here?

Yes — the .ts file is processed inside your browser tab and never uploaded. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab. Close the tab and the file is gone from memory.

Where will the MKV file work?

Chrome, Firefox, and Edge can play Matroska files whose codecs they support, but Safari rejects the container on both macOS and iOS. VLC, mpv, and Plex handle .mkv everywhere, and Windows has shipped native Matroska playback since Windows 10.

Will the MKV file be bigger or smaller than my TS?

It depends on the content: built on EBML, a binary XML-like structure that lets the container gain features without breaking older parsers. Convert one representative file first and compare before batch-processing a large set.

What happens to the metadata in my TS file?

This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, broadcast service tables (SDT/EIT) can carry channel names and program-guide data, but there is no field for user tagging; none of it is transmitted anywhere because the file never leaves your browser.
