# Convert MOV to MP4

ToolSugar converts MOV to MP4 in your browser after checking how the file was recorded. MOVs that hold H.264 video move into MP4 in seconds with no quality loss. MOVs from an iPhone set to High Efficiency hold HEVC, which many Windows and web players cannot read, so those are re-encoded to H.264 on your device, which takes longer.

Runs on your device

## How it works

1. Choose a MOV file from your iPhone, Mac or camera.
2. Leave the method on Copy when possible.
3. Press Convert to MP4 and keep the tab open.
4. Read whether the video was copied or re-encoded, then download it.

## Key facts

- **H.264 MOV**: Copied into MP4 with no quality change
- **HEVC MOV from iPhone**: Re-encoded to H.264, limited to 120 MB on a computer
- **File limit when copying**: 500 MB on a computer, 250 MB on a phone
- **Tracks kept**: The first video and first audio track
- **First run**: Some jobs download a 32 MB video engine once, then your browser reuses it
- **Your file**: Processed inside this tab and never uploaded

## Common uses

- Send an iPhone video to a friend who uses Windows.
- Upload a screen recording from a Mac to a site that rejects MOV.
- Add QuickTime exports to an editor that expects MP4.
- Attach a phone clip to a form that lists MP4 only.

## Questions

### Why is my iPhone video slow to convert?

Recent iPhones record HEVC by default, and it has to be fully re-encoded for H.264 players. To skip this next time, set Settings, Camera, Formats to Most Compatible, and those videos will convert in seconds.

### Does converting a MOV lose quality?

Not when the MOV holds H.264, because the same video data is copied into a new container. HEVC files are re-encoded, which loses a small amount of quality that is hard to see at the settings used here.

### Are Dolby Vision and HDR clips preserved?

No. A re-encoded HDR clip becomes standard 8 bit H.264 without tone mapping, so colors can look washed out. For HDR footage, export from the Photos app or an editor with HDR turned off first.

### Is my video uploaded anywhere?

No. The video engine runs inside your browser tab and reads the file from your device. ToolSugar's servers never receive it, and closing the tab clears the working copy from memory.
