SquishClipConvert MOV to MP4
Fix iPhone and DJI MOV files that won't play on Windows or open in your editor — remuxed instantly on your device.
Why your iPhone MOV won't play on Windows
iPhones record video as MOV files using either H.264 or HEVC (H.265). Windows supports MP4 natively but MOV support is patchy — Windows Media Player often refuses to open them, and many apps require an extra codec pack. Converting to MP4 fixes this instantly, usually without re-encoding a single frame.
DJI drones also record as MOV. The same problem applies: perfectly good 4K footage that refuses to open on a PC or import into a Windows editor.
Remux vs. transcode
Most MOV files contain H.264 video — the same codec that MP4 uses. Converting them to MP4 is a remux: the video stream is copied directly, with no quality loss and no re-encoding delay. The process takes seconds even for a 4K file.
If the MOV uses HEVC video, Windows still needs codec support. A full H.264 transcode ensures universal compatibility — that option is on the roadmap for a future update.
Nothing is uploaded
The conversion runs in your browser. Your vacation footage, drone clips, or work recordings never travel over the internet — they're processed and available to download immediately, even on a slow connection.

Frequently asked questions
Does MOV to MP4 keep the full video quality?
Yes, as long as the remux path is used (H.264 video). The video stream is copied frame-for-frame. HEVC video may need a full transcode for compatibility, which is on the roadmap.
Will it work on a DJI or GoPro MOV file?
Yes. DJI and GoPro MOV files are standard ISOBMFF containers and remux cleanly to MP4.
Why does my MOV not import into Premiere?
Premiere can struggle with MOV files that use PCM audio or have unusual codec flags. Converting to MP4 with AAC audio usually resolves the issue.
