Compress MOV
Turn large iPhone and camera MOV files into compact MP4 videos.
Files are processed on our server in Europe. Download links expire after 60 minutes; files are then deleted automatically.
Why use Video Compressor
Private and secure
Your video is sent over an encrypted connection to our server in Europe and stored under a random ID. It is never shared with third parties or used to train AI. Download links expire after 60 minutes; files are then deleted automatically, normally within 75 minutes. Read the privacy policy
Honest results
Choose quality, resolution or a target size. Progress comes from the encoder itself, and the result shows the exact size saved, even when a target can't be met.
Free, no sign-up
Video Compressor is free with no account, no watermark and no ads. It works in any modern browser on phone or desktop.
In short
Compress MOV takes QuickTime MOV files, including iPhone HEVC and HDR recordings, and produces a smaller MP4 with H.264 and AAC. Portrait videos stay upright. HDR footage is converted to standard dynamic range so it looks right on every screen. Because the format changes from MOV to MP4, the result shows the size change explicitly.

Why iPhone videos are so big
iPhones record 4K at high frame rates and bitrates by default. A one-minute clip can be several hundred megabytes. For sharing, 1080p or 720p at a sensible quality is usually indistinguishable on a phone screen.
HDR and rotation
iPhones store orientation as metadata and often record in HDR (Dolby Vision/HLG). We apply the rotation to the picture itself and tone-map HDR to SDR, so the MP4 looks correct in apps that ignore those tags.
Questions
Is this compression or conversion?
Both: the container changes from MOV to MP4 and the video is re-encoded smaller. If you mainly need a format change at the best quality, use MOV to MP4.
Is my iPhone video's location data kept?
No. Metadata such as location and device model is removed from the output.
What happens to my video after compression?
It's stored under a random ID on our server in Europe. The download link expires after 60 minutes and the video is then deleted automatically, normally within 75 minutes. Canceling deletes it immediately.
The compressed video won't play. What can I do?
Output is standard MP4 with H.264 video and AAC audio, which plays on nearly every device. If an old TV or car screen refuses it, compress again with "Works on older devices" under Advanced settings.
