MOV to MP4

An iPhone video that Windows won't preview and Android won't play — usually the problem is only the wrapper. Swap it for MP4 in seconds, without touching the footage.

Same video, different label

MOV is Apple's container, and iPhones and Macs produce it by the gigabyte. The footage inside is ordinary H.264 or HEVC — the same thing MP4 carries — yet Windows apps, Android phones and half the web's upload forms reject the file on sight. The incompatibility is the box, not the video.

So this tool usually just changes the box: a remux that finishes in seconds and leaves every frame bit-identical, because nothing was re-encoded. When a MOV carries something MP4 genuinely cannot hold — old QuickTime codecs, editing-oriented formats — it falls back to a real re-encode automatically.

Family footage stays home

Videos of kids and holidays are the files people least want on an anonymous server, and classic converter sites ask for exactly that. Here the file is repacked by your own browser and never leaves the device.

Frequently asked questions

Why is the conversion instant?
Because usually nothing is converted at all — the video is simply repacked (remuxed) into the MP4 box unchanged, like moving papers into a new folder. Instant and lossless go together here.
My iPhone video is HEVC — will it work?
Yes — HEVC (the space-saving format newer iPhones record in) fits in MP4 fine, so it repacks too. Note that very old devices can't play HEVC at all; if that's your audience, run the result through the video compressor to get the universally supported H.264.
Does the quality drop?
On the repack path, zero — the result is byte-for-byte the same video. Only for rare exotic formats does the tool fall back to a real conversion, with the normal small cost of any encode.
