How to convert MKV to MOV
Add your MKV videos
Drag and drop MKV files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Choose quality (optional)
Balanced quality suits most videos. If the codecs already fit MOV, Fylo repackages the file instead of re-encoding it, with no quality loss.
Convert and download
Click Convert, then download each MOV file or all of them as one ZIP.
Why convert MKV to MOV?
Apple's editing apps don't import Matroska files. Converting to MOV lets you edit downloads or OBS recordings saved as MKV.
What happens when you convert MKV to MOV?
As with MP4, H.264 video is copied and only incompatible audio is converted to AAC, so most conversions are quick and lossless for the picture. Other video codecs are re-encoded to H.264.
How does Fylo convert MKV to MOV?
Fylo reads the MKV with ffmpeg compiled to WebAssembly and writes H.264 (x264, CRF 23) with AAC audio in a QuickTime container. Most MKV files already contain H.264 video, so Fylo usually copies the video without re-encoding (and converts only the audio if needed), which is fast and lossless. Only the first video and audio track are kept, and the original resolution is preserved unless you pick 1080p, 720p or 480p under Advanced.
What's the difference between MKV and MOV?
MKV is the Matroska container, an open standard first released in 2002. It can hold virtually any video, audio or subtitle codec, and any number of tracks — so one file can carry several languages, director's commentary and subtitles. WebM is a restricted subset of Matroska.
MOV is the QuickTime File Format that Apple introduced in 1991. MP4 was later standardised on the same structure, so the two are close relatives. iPhones record MOV files (usually H.264 or HEVC video with AAC audio), and professional cameras and editors use MOV for high-quality ProRes footage.

Frequently asked questions
Can I convert OBS MKV recordings?
Yes. OBS records H.264 in MKV, so Fylo repackages the video quickly.
Are subtitles kept?
No, only the first video and audio track are included.
Is my MKV file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your MKV file is read directly from your device and never sent anywhere.
