Short answer
MOV files can be converted to MP4 in a browser without uploading them. MOV is Apple's QuickTime container and MP4 is the near-universal standard; both often hold the same H.264 video, so the conversion is mainly a container change plus a re-encode for maximum compatibility. iPhone recordings and QuickTime exports are the most common inputs.

MOV and MP4 are close relatives — MP4 was derived from the QuickTime format — but support differs sharply outside Apple's ecosystem. Windows Media Player, many Android devices, older TVs and a lot of web upload forms accept MP4 and reject MOV.
The output uses H.264 video and AAC audio with the metadata index moved to the front of the file, so it starts playing immediately when streamed rather than after a full download.

Frequently asked questions
What is the difference between MOV and MP4?
Both are containers that can hold the same H.264 video and AAC audio. MOV is Apple's QuickTime format and is well supported on Apple devices; MP4 is the international standard and plays almost everywhere.
Will the conversion lose quality?
A small amount, because the video is re-encoded. At the Balanced or High setting the difference is not visible in normal viewing.
Can I convert an iPhone video that uses HEVC?
HEVC (H.265) support in the browser engine is limited. If the conversion fails, re-export the clip from the Photos app with the "Most Compatible" setting, which produces H.264.
Is there a file size limit?
No server limit, since nothing is uploaded. Your device memory is the practical constraint.
