On October 24, 2026, a 10-second 1280×720 MKV (H.264 video, AAC sound) went through this page’s button in each browser, and what came out was read back with ffprobe.

The test file carried a location tag; no converted copy kept it.

When to turn MKV into MOV

QuickTime Player and the apps built on it read MOV and MP4 but not Matroska, so an MKV from a screen recorder or a download just sits there on a Mac, refusing to open.

The MOV holds H.264 video and the MKV’s main sound track as AAC. Extra sound tracks and subtitles in the MKV are left out, so keep the original if you need them.

MKV and MOV, in short

MKV
Matroska, an open container that can hold several sound and subtitle tracks at once. Screen recorders and films use it; many phones, TVs and editing apps won’t open it.
MOV
Apple’s QuickTime format. iPhones and Macs save videos and screen recordings as MOV, and recent iPhones put HEVC video inside, which some computers and apps can’t play.

How to convert

  1. Open the MKV

    Press the button and drop the file, or pick it from your files. It opens in this browser tab: nothing is uploaded, so there is no upload limit to hit.

  2. MOV is already chosen

    The save window opens set to it. Change the file name or the quality if you like.

  3. Save

    The new file is written on your device and downloaded. Several files? Drop them together and they are converted one after another.

What changes, what stays

Picture and length
Nothing is cut or reframed: the video keeps its own picture size and runs from start to end.
Sound
The first sound track, at its own level, in stereo at most.
Quality
Small, Balanced or High; Balanced is chosen to begin with.
Details about you
The file is written from scratch, so none of the original’s metadata comes along: no location, no camera or phone model.

Questions

MOV or MP4: which should I pick for a Mac?

Either opens on a Mac. Choose MP4 if the video will also go to Windows or Android; choose MOV when an app or a person asks for it.

Does it keep 5.1 surround sound?

No. The sound is saved in stereo at most, so a surround track becomes two channels.

Can I convert a large MKV film?

Nothing is uploaded, so Shycut sets no size limit. Re-encoding takes as long as your computer needs, and the tab has to stay open until it is done.

Your video stays with you.

Open Shycut, drop the video in and export. Free, with no account, and your video never leaves your device.
