Add your MOV file
Drop one or more .mov files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
MOV to MP4
Converting .mov video to .mp4 means re-encoding the picture and sound into a different container and codec family, and this page does it entirely in your browser. Free, private, and validated — the file never leaves your browser.

Converting .mov video to .mp4 means re-encoding the picture and sound into a different container and codec family, and this page does it entirely in your browser. A .mov file is Apple's QuickTime movie container, which stores video, audio, text, and timecode tracks in a flexible atom-based layout. iPhones, iPads, and professional cameras that record ProRes all write .mov, so the extension shows up constantly in editing workflows.
An .mp4 file is a multimedia container that bundles compressed video, audio, subtitles, and chapter data into a single stream-friendly package. It is the default delivery format for nearly every phone, camera, and video platform, which makes .mp4 the safest target when a clip has to play everywhere. For this route the practical draw is plays natively in every modern browser, operating system, and mobile device and streams efficiently once faststart or fragmentation is applied — balanced against fewer track, attachment, and chapter features than Matroska, which is worth knowing before you commit a large batch.
Why convert MOV to MP4?
MOV files come off iPhones and Macs by default, and then promptly refuse to play on the Windows laptop, Android phone, or web page they were sent to. MP4 is the same technical family — both descend from the QuickTime container — but with universal support. Converting MOV to MP4 is less about changing the video and more about changing its passport: same footage, accepted everywhere, usually with no visible quality difference at the default settings.
MOV vs MP4 at a glance
| Aspect | QuickTime video (.mov) | MP4 video (.mp4) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | media lives in a hierarchy of atoms, each declaring its own size and type, which makes the format easy to extend | typically carries H.264/AVC or H.265/HEVC video with AAC audio, though the box structure also accepts AV1, MP3, and timed-text tracks |
| Strongest at | importing iPhone footage into an edit without conversion | publishing video to the web, social media, or a client who has not specified a format |
| Weak spot | proRes recordings consume enormous disk space | fewer track, attachment, and chapter features than Matroska |
| Metadata | quickTime metadata atoms and keys, including camera model, location, and timecode data written by iPhones and professional cameras | iTunes-style metadata atoms (title, artist, cover art) plus XMP and per-track language tags; ID3 is not native to the container |
Pick MP4 as the output
Select .mp4 in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MP4 is selectable, the route is real and validated.
Convert on your device
Press Convert. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MP4 file. Outputs keep the original filename with the .mp4 extension.
MOV to MP4 questions, answered
Will converting MOV to MP4 lose quality?
Both sides are re-encoded, so expect a small generation loss controlled by the quality setting: mov is container-oriented and mp4 is container-oriented. For visually or audibly transparent results keep quality high; for smaller files lower it and compare.
Is it private to convert MOV files here?
Yes — the .mov file is processed inside your browser tab and never uploaded. The conversion runs on an FFmpeg engine compiled to WebAssembly, executing entirely inside your browser tab. Close the tab and the file is gone from memory.
Where will the MP4 file work?
Every current browser, including Chrome, Firefox, Safari, and Edge, plays H.264 .mp4 files without plugins, and hardware decoding is ubiquitous on phones and televisions. Files using HEVC inside the container are the main exception: Apple devices handle them well, while Firefox depends on the operating system's decoder.
Will the MP4 file be bigger or smaller than my MOV?
It depends on the content: typically carries H.264/AVC or H.265/HEVC video with AAC audio, though the box structure also accepts AV1, MP3, and timed-text tracks. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my MOV file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, quickTime metadata atoms and keys, including camera model, location, and timecode data written by iPhones and professional cameras; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert MP4 back to MOV?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .mov → .mp4 → .mov is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
