Add files from where they live
Drop a MOV file on the box, browse for it, or import it from Dropbox, Google Drive or a link. You can add more files later, and each file gets its own result.
Free MOV to MP4 converter
Convert MOV to MP4 online. Add a file, confirm MP4 and download it. A single file needs no account.
Converting MOV to MP4 moves Apple's QuickTime video into the container that Windows, Android, browsers and smart TVs expect. The two formats are closely related, so ordinary iPhone clips change little. One thing to know: if the picture inside stays HEVC, some older devices and Windows apps still will not play it, even as MP4.
Transfers use HTTPS, and files converted on the free tier are deleted within 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the MP4 file once before you share it.
FromMOVLossy
MOV (QuickTime File Format)
Apple's QuickTime container, introduced in 1991. It stores video, audio, timecode and text tracks, and is what iPhones, Macs and many cameras record. Typical contents are H.264 or HEVC with AAC audio, or ProRes in editing workflows.
ToMP4Lossy
MP4 (MPEG-4 Part 14)
An ISO-standard container that was modelled on the QuickTime file structure, which is why the two are close relatives. It usually carries H.264 or HEVC video with AAC audio and is accepted by nearly every phone, browser and television.

Save the MP4 file, copy a share link or convert it to another format. Free-tier output expires on its own after 24 hours.
What changes
- Compatibility widens. MOV depends on QuickTime support, which Windows and many televisions lack out of the box, whereas MP4 is the default expectation of almost every player and upload form.
- Professional codecs do not carry over. ProRes is not a normal MP4 payload, so that footage is re-encoded to a delivery codec and typically shrinks to a small fraction of its size.
- Extra tracks may be left behind. Timecode, multiple audio streams, chapter markers and the metadata that pairs a Live Photo clip with its still are QuickTime features with weaker MP4 equivalents.
- High dynamic range needs care. iPhone Dolby Vision and HDR10 recordings can lose their HDR metadata or be converted to standard range, which changes brightness and colour.

What are the limits for MOV to MP4?
Size
The upload box shows the live size limit before you add a file. Signing in raises it, and paid plans raise it further.
Formats
MOV in, MP4 out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are deleted automatically within 24 hours after the job finishes.
Limits worth knowing
- A new container does not fix codec support. HEVC video in an MP4 still fails on players without an HEVC decoder, which includes Windows installations lacking the HEVC extension.
- Re-encoding is lossy. When the video must be recompressed, as with ProRes, a little detail is discarded, though it is rarely visible at sensible sizes.
- Slow-motion and cinematic-mode effects applied by the Photos app are edits stored alongside the file, so the converted clip may play as the plain original recording.

MOV to MP4 FAQs
Is MOV the same as MP4?
Not quite, but they are close relatives. MP4 was standardised from Apple's QuickTime file structure, and both commonly hold the same H.264 or HEVC video and AAC audio. The differences are in what else each allows: MOV accepts ProRes, timecode and other Apple-specific tracks, while MP4 is stricter and far more widely supported.
Does converting MOV to MP4 lose quality?
It depends on what is inside the MOV. When the streams are already H.264 or HEVC with AAC, they can in principle be moved to MP4 untouched with no loss at all. When the video has to be recompressed, as with ProRes or other editing codecs, some detail is discarded, usually too little to notice in normal viewing.
Why won't my iPhone video play on Windows?
Usually the cause is the codec, not the file extension. iPhones set to High Efficiency record HEVC, and Windows needs a separate HEVC extension from the Microsoft Store before its built-in apps can decode it. Older editing programs have the same gap. A player such as VLC brings its own decoder, and an H.264 file plays almost anywhere.
Why is my MP4 so much smaller than the MOV?
A big drop almost always means the source used an editing codec. ProRes keeps every frame nearly intact and can use well over a hundred megabits per second, so a few minutes fills gigabytes. Delivery codecs such as H.264 store mostly the differences between frames, which commonly cuts the size by ten times or more at similar visible quality.
Can I just rename a .mov file to .mp4?
Sometimes it appears to work, but it is not a conversion. Because the two structures are similar, lenient players will open a renamed file, while stricter software, upload checkers and some televisions reject it. Renaming also does nothing about codecs MP4 does not normally carry. Rewriting the container properly is the reliable route.
Will HDR or Dolby Vision survive MOV to MP4 conversion?
Not reliably. iPhone HDR video is HEVC with Dolby Vision metadata layered on an HLG signal, and that metadata is easily dropped when a file is rewritten or re-encoded. The result may play as plain HLG, or as standard range with flatter or shifted colours. If HDR matters, check the converted file on the screen you intend to use.
