MOV to MP4
on iPhone & Android.
iPhone records MOV by default, but MP4 is what every Windows player, web uploader, and edit app expects. Fileroom converts MOV → MP4 on your phone using the hardware video pipeline — fast, no upload.
Free tier — 10 conversions / day, files up to 50 MB.
Why convert MOV to MP4?
- MP4 is the universal video container — Windows, YouTube, web players, every NLE.
- Most MOV files already use H.264 or HEVC; Fileroom can stream-copy them into MP4 with zero quality loss.
- Hardware acceleration means a 5-minute 4K clip converts in seconds, not minutes.
- Everything stays on-device — large videos never leave your phone.
How to convert MOV to MP4
- 01
Pick the MOV video
Open Fileroom and select a MOV file from Photos or Files.
- 02
Choose MP4
Pick MP4 as the output. If the source codec is already H.264 or HEVC, Fileroom will stream-copy — no re-encode, no quality loss.
- 03
Convert
Tap Convert. The MP4 saves alongside your library; share or AirDrop straight from the success screen.
Frequently asked
- Will MOV → MP4 reduce quality?
- No, when Fileroom can stream-copy. MOV and MP4 are both container formats — if the video and audio codecs inside are already compatible (H.264, HEVC, AAC), the conversion just rewrites the container with zero quality loss.
- How long does converting a long video take?
- Stream-copy converts at hundreds of megabytes per second — a 4K 5-minute clip finishes in seconds. Full re-encodes are slower and depend on the device's hardware encoder.
- Can I trim the video while converting?
- Yes — open Trim Video from the home screen first, set in/out points, then export. Trim and convert can be done in the same pass.
