Does converting MOV to MP4 lose quality?

Not when the video is H.264: it's rewrapped, so the picture is bit-for-bit the same. iPhone HEVC videos converted to H.264 are re-encoded at high quality; the difference is hard to see, but the file is usually larger because H.264 is less efficient than HEVC.

Why does my iPhone video take longer than a screen recording?

iPhones record in HEVC by default (Settings → Camera → Formats → High Efficiency). Turning HEVC into H.264 means re-encoding every frame on your device. Screen recordings and Most Compatible videos are already H.264, so they only need rewrapping.

Can I just rename .mov to .mp4?

Sometimes it plays, but it isn't a real conversion. The file still has QuickTime-only parts, and HEVC video still won't open on devices without HEVC support. Rewrapping it properly takes a few seconds here.

How do I make my iPhone record MP4-friendly video?

Open Settings → Camera → Formats and choose Most Compatible. New videos are then recorded in H.264, and any MOV from that point converts to MP4 in seconds. The trade-off is larger files on your phone.

Is there a size limit?

Videos up to 100 MB. Everything runs inside your browser's memory, and this keeps it working on laptops and phones. For longer videos, trim them first or convert on a computer with plenty of free memory.

Is my video uploaded anywhere?

No. The converter downloads a video engine (about 30 MB, cached after the first time) and runs it in this tab. Your video stays on your device and is cleared when you close the page.

MOV to MP4

Why a MOV sometimes needs to become an MP4

MOV is Apple's QuickTime container, and it's what iPhones, iPads and Macs save videos and screen recordings as. MP4 is the same kind of container with wider support: Windows, Android, smart TVs, video editors and most websites expect it. The video inside is often identical, which is why a good converter doesn't need to re-encode anything when the codec already fits.

This tool checks what's inside your MOV first. H.264 video (screen recordings, older iPhones, many cameras) is rewrapped into an MP4 in seconds, with the picture and sound untouched. iPhone videos recorded in High Efficiency use HEVC, which some devices can't play, so by default those are re-encoded to H.264. If you only need an .mp4 file for an Apple device or a modern PC, choose Keep original codec and it's done in seconds too.

A MOV converter that doesn't waste your time

Fast when it can be, compatible when it has to be.

Seconds for H.264 videos

When the video is already H.264, it's copied into an MP4 container instead of re-encoded. No quality loss and no waiting.

HEVC to H.264 when needed

iPhone High Efficiency videos are converted to H.264, the format every Windows PC, Android phone and website accepts.

HDR handled properly

iPhones record HDR video by default. When it's re-encoded, it's tone-mapped to standard range so it doesn't look washed out on other screens.

Sound kept

The audio track comes along. AAC audio is copied as-is; anything MP4 can't carry is converted to AAC.

Nothing is uploaded

The video is processed on your own device. Useful for family clips, work recordings and anything you'd rather not hand to a server.

Orientation stays right

Portrait iPhone videos stay portrait. Extra tracks that MP4 doesn't support, such as iPhone camera metadata, are left out.
