MOV to MP4 Converter
Turn .MOV videos from iPhones and Macs into MP4 — usually in seconds, with no loss.

Leave this off for an instant, lossless copy. H.264 files are larger and converting takes a while.

About the MOV to MP4 Converter
iPhones, iPads, Macs and many cameras save video as .MOV (Apple’s QuickTime format). MOV and MP4 are both built on the ISO base media file format, so when the video is H.264 or HEVC and the audio is AAC — which is what an iPhone records — the tracks can simply be moved into an MP4 file. That takes seconds, keeps the exact original quality, and keeps the rotation, the recording date, the device model and the location (which you can choose to remove).
Two things are converted rather than copied: Apple ProRes video (from iPhone Pro models, Final Cut and cameras) becomes H.264, and uncompressed PCM audio becomes AAC, because MP4 players do not support them. If an older Windows PC, Android phone or TV cannot play HEVC, tick Convert HEVC to H.264. Everything happens in your browser; the video is never uploaded.
How to use it
- Drop the .MOV file on the box, or click Choose a MOV file. The page shows its tracks and the metadata it found (device, date, location).
- If you will share the video publicly, tick Remove location (GPS) so the MP4 does not reveal where it was filmed.
- If the video is HEVC and has to play on older devices, tick Convert HEVC to H.264 and pick a quality. Otherwise leave it off for an instant, lossless copy.
- Press Convert to MP4, then preview and Download the MP4.
Examples
IMG_0042.MOV · HEVC 3840×2160, 30 fps · AAC stereo
IMG_0042.mp4 — tracks copied, same quality and almost the same size, ready in seconds.
IMG_0042.MOV · HEVC · Convert HEVC to H.264 · Quality High
IMG_0042.mp4 with H.264 video (larger than the HEVC original) and the original AAC audio.
Needs a browser that can decode HEVC: Safari on Apple devices, or Chrome/Edge on most recent Windows PCs and Macs.
interview.mov · Apple ProRes 422 · PCM audio
interview.mp4 with H.264 video and AAC audio — a fraction of the size, playable everywhere.
HEVC or H.264?
On an iPhone, Settings › Camera › Formats decides the codec: High Efficiency records HEVC (H.265), Most Compatible records H.264. Both fit in MP4. HEVC files are smaller, and Apple devices, Windows 10/11 PCs with HEVC support, recent Android phones and most smart TVs from the last few years play them; some older PCs, TVs and web uploaders do not. When in doubt, convert to H.264 — it plays everywhere, at the cost of a larger file and some re-encoding time.
What happens to rotation, date and location?
Phones record in landscape and store the turn needed for portrait videos as rotation metadata; it is copied, so the MP4 shows the right way up. Apple’s metadata — creation date, make and model, software version and location (the com.apple.quicktime.location.ISO6709 key) — is copied into the MP4 as well. A location stored the older way, in a QuickTime ©xyz atom or a 3GPP loci box (common in files from Android phones and some cameras), is written into that same Apple key so it is not lost. Tick Remove location (GPS) to leave the location out; everything else stays.
HDR videos
Copying keeps the HDR picture: HEVC HDR (HLG) colour information is carried into the MP4. Dolby Vision metadata from iPhone HDR videos is not carried over, so Dolby Vision players show the standard HLG HDR version instead. Converting HDR video to H.264 produces SDR, so colours and highlights can look different.
Limitations
- Converting HEVC to H.264 needs a hardware HEVC decoder that the browser can use; if there is none, the page explains this and offers the lossless copy instead.
- Timecode tracks and timed-metadata tracks are not copied — only the main video and audio tracks.
- Audio formats MP4 cannot carry well (PCM, and rare ones such as ALAC) are converted to AAC or, if the browser cannot decode them, left out with a warning.
- Very large files are held in memory until you download them unless you use “Save straight to a file” (Chrome/Edge on a computer).

Frequently asked questions
Does converting MOV to MP4 lose quality?
Not when the tracks are copied, which is the default for iPhone videos: the MP4 contains the identical video and audio. Only ProRes, PCM audio, or HEVC you choose to convert to H.264 are re-encoded.
Why is the MP4 almost the same size as the MOV?
Because nothing was re-encoded — the same data is just packaged differently. To make the file smaller, use the Video Compressor.
Is my video uploaded?
No. The MOV is read and converted inside your browser; nothing is sent to a server.
Can I remove other metadata as well as the location?
No — the page only offers to remove the location, which is the privacy-sensitive part. Date, device and software tags stay so photo apps can still sort the video correctly.
Why can’t I tick “Convert HEVC to H.264”?
Your browser cannot decode HEVC on this device. Repackaging still works (it does not need decoding). To convert, open this page in Safari on a Mac, iPhone or iPad, or in Chrome or Edge on a recent Windows PC.
