How to convert MP4 to MOV
Add your MP4 videos
Drag and drop MP4 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 MP4 to MOV?
Final Cut Pro, iMovie and some Mac workflows prefer QuickTime MOV files, and a few broadcast and editing pipelines require the .mov extension. Converting gives you a file those tools import without complaint.
What happens when you convert MP4 to MOV?
MP4 and MOV share the same structure, so when the MP4 holds H.264 or HEVC video with AAC audio — almost always — Fylo simply moves the streams into a MOV container. Quality and file size stay the same, and even long videos finish quickly. Other codecs are re-encoded to H.264 and AAC.
How does Fylo convert MP4 to MOV?
Fylo reads the MP4 with ffmpeg compiled to WebAssembly and writes H.264 (x264, CRF 23) with AAC audio in a QuickTime container. Most MP4 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 MP4 and MOV?
MP4 (MPEG-4 Part 14) is a container format standardised in 2001 and based on Apple's QuickTime file structure. A container holds separately compressed video and audio streams plus metadata such as subtitles, chapters and cover art. Most MP4s use H.264 video and AAC audio; newer files may use H.265 (HEVC) or AV1.
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
Is MOV better quality than MP4?
No. They are containers; quality depends on the codec inside. A repackaged MOV is bit-for-bit the same video as the MP4.
Will the MOV play on Windows?
Usually yes in modern players like VLC or the Windows Media Player app, because the video inside is H.264. MP4 remains the safer choice for Windows and Android.
Is my MP4 file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your MP4 file is read directly from your device and never sent anywhere.
