Convert MOV to MP4 in your browser
Turn iPhone and QuickTime MOV videos into MP4 that plays everywhere — often in seconds, because compatible streams are copied instead of re-encoded. Nothing is uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Why MOV files don’t play
MOV is Apple’s QuickTime container. Windows players, Android phones, many editors and upload forms prefer MP4, the most widely supported video container.
Fast when possible
iPhone videos already use H.264 or HEVC inside the MOV, so the converter can copy them straight into MP4 without re-encoding — no quality loss and very fast.
FAQ
Will I lose quality?
When streams can be copied, no. If re-encoding is needed, the default quality is visually lossless for most clips.
My iPhone video is HEVC — will it play?
Most devices play HEVC MP4. For maximum compatibility, pick H.264 with the Video Resizer.
What can you do with a video converter?
Creators convert iPhone MOV clips and screen-recorded WebM files to MP4 before posting to Instagram, TikTok or YouTube; podcasters and students pull MP3 audio from interviews and lectures; developers and support teams turn short screen captures into GIFs for docs and chats; editors rewrap MKV recordings into MP4 so their NLE accepts them; and motion designers convert Animdock WebM exports into whatever format a client or platform needs.
