This tool converts MOV files to MP4 right in your browser. Drop the file, wait a moment for the assessment, convert — the video is processed on your device and never uploaded anywhere. Wherever possible the picture data is repackaged unchanged, which takes seconds and costs no quality.

What is MOV?

MOV is Apple's QuickTime container, the default of the iPhone camera, of iMovie and of Final Cut Pro. It is the direct ancestor of MP4: the ISO base media file format (ISO/IEC 14496-12), on which MP4 rests, was derived from the QuickTime file format — which is why the two files are built almost identically inside. A MOV usually carries H.264 or HEVC pictures with AAC sound; Apple puts 4K/30 recordings at roughly 170 MB per minute in the iOS camera settings. Outside the Apple world, .mov is often rejected by upload forms and older players even though the content would play fine.

What is MP4?

MP4 (ISO/IEC 14496-14) is the everyday video container: H.264 or HEVC pictures plus an AAC audio track, produced by every phone camera, screen recorder and streaming platform. Container and codec are two different things — an .mp4 file says how the data is packaged, not how it was compressed. That distinction is what makes fast conversion possible: if the pictures inside are already H.264 or HEVC, they can simply be repackaged instead of re-encoded. A typical consumer clip carries its sound at 128 to 192 kbit/s AAC.

Why convert MOV to MP4?

A MOV almost always comes from an iPhone, iMovie or Final Cut. It plays everywhere on Apple devices, but Windows software, TVs, projectors, learning platforms and plenty of upload forms only know .mp4 and reject the file. Converting gives the very same recording the packaging everyone accepts.

Why is MOV to MP4 so fast?

Because the two are built almost identically inside: the ISO base media file format (ISO/IEC 14496-12) that MP4 rests on was derived from Apple’s QuickTime file format. If the MOV already holds H.264 or HEVC with AAC sound — the normal case for iPhone recordings — the finished data packets are merely rearranged into an MP4 frame. Nothing is decoded, nothing recalculated: a two-minute clip is done in seconds and is identical to the original frame for frame.

What are the limits?

Not every MOV is that easy: if it came out of an editing suite as ProRes or an animation codec, the content does not fit into an MP4 other people can play. Then it is honestly re-encoded — which takes roughly as long as the video itself, depending on your device, and costs quality once. The tool tells you before you start which of the two paths applies. Subtitle tracks and slow-motion metadata from the iPhone camera are not carried over.

How to convert

1. Drop your MOV file(s) into the area or click to browse. 2. The tool reads the header and tells you whether it will repackage or re-encode, and roughly how long that takes. 3. Click Convert — progress is shown per file and you can cancel at any time. 4. Download the MP4; multiple files come as a ZIP.

Frequently asked questions

Is converting MOV to MP4 free?

Yes, completely free and without signup. There are no watermarks and no file-size limits beyond what your browser can handle.

Are my files uploaded?

No. The conversion runs entirely in your browser — your MOV file never leaves your device and is not sent to any server.

Do I lose quality converting MOV to MP4?

Usually not. If the MOV already holds H.264 or HEVC with AAC or MP3 sound, the picture data is copied into the MP4 container unchanged — bit for bit the same image, just packaged differently, and done in seconds. Only when the codecs do not fit MP4 (VP9 or AV1, for example) is it re-encoded, which costs a little quality once. The tool shows you which path applies to your file before you start.

Can I convert several files at once?

Yes. Just drop multiple files into the area — they are converted together and you can download them as a ZIP.

How big and how long may the video be?

Up to 2 GB in size. When the file is only repackaged, up to two hours of runtime works — that is fast and needs little memory. When it has to be re-encoded, the limit is 30 minutes, because every frame goes through the encoder individually and the tab has to stay open. Which case applies to your file is shown before you start.

What happens to extra audio and subtitle tracks?

One video and one audio track are carried over — that is what an MP4 transports reliably everywhere. Additional language versions, embedded subtitles and chapter marks stay behind. If you need them, keep the original file as well.

Why does it take seconds for some files and minutes for others?

Because there are two paths. If the codecs fit into an MP4 container, the finished data packets are merely rearranged — pure copying, done in seconds. If they do not, every frame has to be decoded and encoded again, and then the wait is roughly in the order of the video length. The work is done by your device’s encoder, not by a server.
