Drop MKV (Matroska) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Save the M2TS, or download everything as one ZIP if you converted several files.
The MKV to M2TS converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MKV does not play on iPhones, in QuickTime or in most browsers and editors. M2TS is what Blu-ray authoring tools and AVCHD-compatible players expect. MKV is at home in films with several audio and subtitle tracks; M2TS is the usual choice for blu-ray discs and AVCHD camcorder footage.
The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
This pair uses the compatibility engine, ffmpeg built for the browser, because M2TS cannot be written by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
MKV is an open container that can hold practically any video and audio format plus multiple subtitle tracks. That flexibility is why it is popular for films, and why Apple devices and browsers refuse it.

MKV converterM2TS is the transport stream container of Blu-ray discs and of AVCHD camcorders from Sony and Panasonic, which write the same files with an .mts extension. The files are large because the bitrate is high.

No. The MKV to M2TS conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
It depends on what is inside the MKV. When its video and audio are already in a form M2TS can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MKV file, press Convert and save the M2TS. There is nothing to install.
Yes. MKV to M2TS runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
