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 MOV, or download everything as one ZIP if you converted several files.
The MKV to MOV 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. MOV is what Final Cut, iMovie and other Apple tools prefer. MKV is at home in films with several audio and subtitle tracks; MOV is the usual choice for recording and editing on Apple devices.
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.
The conversion uses your browser's own video and audio codecs (WebCodecs), with hardware acceleration where the device has it; the file is read from disk as it goes and can be up to 2 GB. Where the browser lacks a codec, the page falls back to the compatibility engine. A video over 500 MB cannot be kept at full quality in browser memory; choosing a lower resolution or quality under Options lets it fit.
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.
Opens in VLC, Plex and many TVs; not iPhones, QuickTime or most browsers
MKV converterMOV is Apple's QuickTime container and what iPhones and Macs record. MP4 was based on it, so the two are close relatives and often hold exactly the same video and audio streams inside.

No. The MKV to MOV 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 MOV 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 MOV. There is nothing to install.
Yes. Files up to 2 GB are accepted, and a video over 500 MB needs a lower resolution or quality chosen under Options so the result fits in memory. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
