Conversion
Copies the video as-is when it's already H.264 (seconds, no quality loss). iPhone HEVC videos are converted to H.264 so they play everywhere.
The first time you use a video tool, your browser downloads the video engine (about 32 MB, once). Processing happens on your device, so long or 4K videos can take a few minutes — keep this tab open.

Frequently asked questions
Is my video uploaded?
No. The conversion runs inside your browser using WebAssembly. Your videos never leave your device.
Will I lose quality?
Usually not. If your MOV already uses H.264, the video is copied into an MP4 container without re-encoding — identical quality in seconds. HEVC videos are re-encoded at high quality so they play everywhere.
Why won't my iPhone video play on Windows?
iPhones record in HEVC (H.265) by default, which many Windows PCs and websites can't play. “Auto” or “Most compatible” converts it to H.264, which plays on every device.
How long does it take?
Fast copy takes seconds. Re-encoding runs on your device, so a 1-minute 1080p video may take a few minutes on a laptop and longer on a phone.
Is there a size limit?
Files up to 2 GB can be processed, but very long or 4K videos need a lot of memory. On phones, shorter clips work best.
