Frequently asked questions
Is this TS to MKV converter free?+
Yes, with no watermark and no account. The engine runs locally in your browser, so there's no server queue limiting usage.
Is my video uploaded to a server?+
No. Orbfile uses your browser's own built-in media codecs (via the WebCodecs API and Mediabunny), so encoding happens entirely on your device.
How long will it take?+
It depends on your device and the video's length and resolution — expect roughly real-time to a few times real-time for typical clips.
Is there a maximum file size?+
There's no fixed upload limit — since everything runs on your device, the practical limit is your browser's available memory, which handles typical clips and even fairly long recordings without issue.
How do I convert TS to MKV?+
Drop your TS file into the box above — Orbfile re-encodes it to MKV using your browser's own codecs and gives you a download link when it's done.
About TS and MKV
What is TS?
TS (MPEG Transport Stream) is a broadcast- and camera-oriented format designed to stay resilient during streaming or recording interruptions.
Full TS format guide →What is MKV?
MKV (Matroska) is a flexible open container that can hold multiple audio tracks, subtitles, and chapters alongside the video.
Full MKV format guide →People usually reach for this conversion because MKV offers supports multiple audio/subtitle tracks in one file, sidestepping a real TS weak spot: less convenient for editing or sharing than MP4. It's especially useful for archiving video with multiple language tracks or subtitles.
How it works

Drop your file in
Drag your video onto the box above, or click it to browse — there's no account to create and no upload to wait on.
- 2
Pick your settings
The output format is already set for this page — just adjust any extra options shown, if there are any.
- 3
Download the result
Your browser processes everything locally and hands you a download link the moment it's done — nothing was ever sent to a server.
Is it private?
Everything happens locally, inside this browser tab. Your video is read from disk, processed with WebAssembly running on your own device, and handed back to you as a download — it's never transmitted anywhere, so there's nothing to intercept and nothing stored on a server.
Common use cases
- Archiving video with multiple language tracks or subtitles

Format details
About TS files+
TS (MPEG Transport Stream) is a broadcast- and camera-oriented format designed to stay resilient during streaming or recording interruptions.
MPEG Transport Stream was designed for broadcast television, where a signal might briefly drop out or arrive slightly out of order, so the format includes built-in error correction and the ability to resynchronize mid-stream rather than failing outright. That resilience is also why many camcorders and broadcast capture cards record directly to .ts files, even though the format is less convenient than MP4 for editing or casual sharing once the footage is off the device.
How to open a TS file
Opens readily in VLC Media Player. For real editing, use DaVinci Resolve, Adobe Premiere Pro.
Good for
- resilient to data loss mid-stream
- common output from camcorders and broadcast equipment
Watch out for
- less convenient for editing or sharing than MP4
About MKV files+
MKV (Matroska) is a flexible open container that can hold multiple audio tracks, subtitles, and chapters alongside the video.
Matroska was designed from the ground up as an open, extensible container, meaning a single MKV file can bundle several audio tracks (say, multiple languages), several subtitle tracks, and chapter markers, all switchable during playback — something older containers like AVI and even MP4 handle less gracefully. That flexibility made it the format of choice for archiving TV shows and films with multiple language options, though a handful of phones and streaming devices still expect MP4 and need MKV converted first.
How to open a MKV file
