Free MOV to MP4 converter

Turn .mov files from an iPhone, a Mac screen recording, or a camera into MP4s that play and upload almost anywhere. Most convert in seconds, because the video itself doesn't need re-encoding.

Runs in your browser. Your video is never uploaded.

How it works

  1. 1

    Choose or drop a video

    iPhone videos, Mac screen recordings, and camera files all work, up to 1 GB.

  2. 2

    Pick Fast or Most compatible

    Fast keeps the video exactly as it is and only changes the file type. Most compatible re-encodes it as H.264 for older PCs and picky upload forms.

  3. 3

    Download the MP4

    Play it in the preview first if you like. Nothing leaves your device.

Why Fast is fast
A MOV and an MP4 can hold the same video and audio. When they do, converting only rewrites the file around them, so there's no quality loss and it takes seconds.
HEVC videos
iPhones record HEVC (H.265) by default. It plays on Apple devices and most newer computers. Choose Most compatible if a Windows PC or website won't play it.
ProRes and other camera formats
Browsers can't decode ProRes, so those files can't be converted here. Export them as H.264 or HEVC from your editing app first.

Questions

Does converting lower the quality?

Not with Fast: the video is copied as it is. Most compatible re-encodes at high quality, which can change it slightly, as any re-encode does.

Which browsers work?

Fast works in current Chrome, Edge, Firefox, and Safari. Most compatible needs the video encoder built into the browser, and the page tells you if yours doesn't have one.

How big a video can I convert?

Up to 1 GB. The MP4 is held in memory until you download it, so very long videos may not fit on a phone.

Is my video uploaded anywhere?

No. The conversion runs in your browser with its built-in video support. Your video never leaves your device.

Converting videos for your team every week?

I set up workflows that convert, compress, and publish video on their own, from a shared folder or a phone straight to your website or channels.
