MOV to MP4 Converter (iPhone Videos)

Every video an iPhone shoots lands in Apple's QuickTime .MOV container, and half the world's software refuses to open it — Windows Media Player, Android gallery apps, older projectors, cheap smart TVs. This converter repackages the same footage as a play-anywhere MP4 right in your browser: H.264 and HEVC clips are stream-copied in seconds with zero quality loss, and nothing you drop here is ever uploaded.

Instant conversion — the streams are copied, no re-encoding, no quality loss

This file needs a re-encode to become {{ toLabel }}. Your browser's hardware encoder does the work — expect roughly the video's playing time or less.

Heads up: this file is over 500 MB. It will still work — everything streams from disk — but a re-encode can take a while, especially on a phone.

Video stream copied untouched — identical quality to the original.

The audio track used a codec this browser could not convert, so the output is silent.

How to use this tool

  1. Drop your MOV file

    AirDrop or copy the video from your iPhone or Mac first — any size works, because the file streams straight from disk and never uploads.

  2. Convert

    iPhone H.264 and HEVC footage is stream-copied into the MP4 container untouched, so most conversions finish in seconds. An optional checkbox re-encodes HEVC to H.264 for very old devices.

  3. Download the MP4

    Same picture, new container — it now opens in Windows, Android, editing apps and web uploaders that rejected the .MOV.

Questions people ask

Why won't my MOV file play on Windows or Android?

MOV is Apple's QuickTime container format. The video inside it is usually perfectly standard — it's the wrapper that Windows Media Player, many Android apps and lots of web uploaders don't read. Repackaging the identical video data as MP4 fixes it without touching a single frame.

Does converting MOV to MP4 lose quality?

Usually not at all. iPhone footage is H.264 or HEVC, and both fit inside MP4, so this tool stream-copies the video bit-for-bit — a container rewrite, not a re-encode. The result is byte-identical picture quality, and it finishes in seconds even for long clips.

My iPhone records HEVC — will the converted MP4 play everywhere?

HEVC-in-MP4 plays on all Apple devices, recent Windows machines, VLC and most modern phones. For genuinely old hardware, tick the "Re-encode HEVC to H.264" option before converting — it takes longer because it is a real re-encode, but H.264 plays on effectively everything made since 2010. (Tip: iPhone Settings → Camera → Formats → "Most Compatible" records H.264 in the first place.)

Is my video uploaded to a server?

No. The container rewrite happens inside your browser and this page has no upload endpoint. That is also why huge files convert instantly — there is no upload wait at all.

Is there a file size limit?

No hard limit — the file streams from disk rather than loading into memory. Stream-copy conversions handle multi-GB files fine; only if a re-encode is needed do we suggest staying under roughly 500 MB on phones.

Can I convert WhatsApp or screen-recording MOVs too?

Yes — any .MOV works, whatever recorded it. Mac screen recordings (also .MOV) are a very common case and stream-copy instantly.
