What to expect when converting MOV to MP4
A 100 MB iPhone MOV typically becomes 70 – 90 MB as MP4 with H.264 encoding.
Quality: If both formats use H.264, the conversion is essentially a container swap, quality is preserved.
Heads up: MP4 doesn't support transparency, so transparent backgrounds in your MOV will be flattened (usually to white).
Best for: sharing iPhone videos with Windows or Android users, embedding in presentations, social media uploads.
Avoid when: you're staying within the Apple ecosystem.
Tip: MOV is just a container for MOV-flavored MP4 content, most "MOV vs MP4" file-size differences are minimal. The bigger gains come from re-encoding (changing codec or bitrate).
MOV to MP4 - iPhone and QuickTime video that uploads anywhere
Anything recorded on an iPhone screen, captured in QuickTime or exported from Final Cut arrives as MOV, and every platform you are likely to upload it to, YouTube, Instagram, Twitter, would rather have MP4. The good news is that this is usually not a real re-encode at all: the video inside is often already H.264, so only the container changes. That makes it both quick and effectively lossless.
MOV vs MP4: the container difference
MOV and MP4 are closely related container formats, MP4 was derived from Apple's QuickTime MOV specification. Both can hold H.264 video and AAC audio. The difference is metadata structure and tool compatibility. When the codecs match, conversion can be a fast "remux" (repackaging the streams without re-encoding) that takes seconds and loses zero quality. When the MOV uses Apple ProRes or other codecs, the video must be re-encoded to H.264, which takes longer but produces a universally playable file.
Convert MOV to MP4 when sharing video with non-Apple users, uploading to social media or video platforms (most prefer MP4), embedding video on websites, or reducing file size from ProRes MOV recordings (ProRes is high-quality but enormous, often 10-50× larger than H.264 MP4 for the same footage).

Use MOV when
- You're editing in Final Cut Pro or iMovie
- You're handing footage to a colourist or professional editor
- The audience is entirely Apple-based (iOS, macOS)
- You're archiving high-quality masters with ProRes
Use MP4 when
- You're sharing video with anyone outside the Apple ecosystem
- You're embedding video on a webpage
- You want maximum playback compatibility
- You're uploading to YouTube, Instagram, LinkedIn, or similar
For any video leaving your machine, MP4 is the safe universal choice. For working footage inside the Apple editing pipeline, MOV is right. If you're shooting on iPhone and sharing to non-Apple users, converting MOV to MP4 is one of the most common video conversions people run, worth doing before the video hits the recipient's inbox.
