How to use this tool
- Choose the iPhone video from Files, Photos export, AirDrop, or your Mac.
- Keep the 25MB target for sharing, or switch to 10MB when a chat or email limit is stricter.
- Compress locally and download the smaller MP4.
Built for large iPhone MOV files
Recent iPhones can save high-resolution HEVC video inside a MOV container. The tool reads MOV metadata, then exports a broadly compatible H.264 MP4.
Best settings for iPhone sharing
Start with 720p, 30 fps, and lower audio bitrate. For longer clips or a strict 10MB target, choose 480p, remove audio, or trim the video first.
No upload while compressing
The browser version processes the iPhone video locally. The original video content is not sent to a cloud transcoding server.
Browser-based compression and privacy
The video file is handled in your browser session. The compression engine runs locally, so the file is not uploaded to a server and no watermark is added.
Supported formats
The first version accepts MP4, MOV, and WebM files up to 500MB. Files from 200MB to 500MB can be processed, but the page warns that browser memory and processing time may be a limit.
FAQ
Can I compress an iPhone MOV video?
Yes. Choose the MOV file, keep MP4 output selected, and the tool will create a smaller MP4 in your browser.
Does this support HEVC iPhone video?
The local tool path has been tested with HEVC video inside a MOV container and exported a playable H.264 MP4. Very unusual camera files may still need another export.
What target size should I use for an iPhone video?
25MB is a practical sharing target for short clips. Use 10MB for stricter chat or email limits, and lower resolution when the estimate warns about quality.
Will my iPhone video be uploaded?
No. Compression runs locally in the browser in this version; you download the smaller file and choose where to send it.
