Three things it keeps

Nothing that matters is lost

Cover frame

The frame you chose

  • Matched to the exact frame by its original timestamp
  • Missing timing is reported, never guessed
  • Want it sharper? Some photos offer high-res candidate frames, with the motion unchanged
Audio & video

Never re-encoded

  • Original audio and video samples, just rewrapped
  • Checked sample by sample before output
  • Note: Apple HEIC → Android JPEG re-encodes the still: different format, and Android’s HEIC support is limited
HDR

Kept, or clearly flagged

  • Ultra HDR gain maps kept with their parameters
  • Unsupported HDR is flagged, never faked
  • Note: Apple gain maps converted for Android may not be bit-exact
  • Note: High-res candidate frames carry no HDR gain map

FAQ

Can’t I just copy the file to my iPhone?

No. The formats differ, so it shows up as a still photo

Will I lose quality?

Video and audio: never, they’re rewrapped and verified. Android → iPhone keeps the photo as is; if you pick a high-res candidate cover instead, that frame is decoded to JPEG without the original HDR. iPhone HEIC → Android JPEG must re-encode the still (Android’s HEIC support is limited), and the HDR gain map may not carry over losslessly

Are my photos uploaded?

No. Everything happens on your Mac

Can I convert back to Android?

Yes. Choose Apple → Android and the recipient’s phone brand

Is it free?

Yes, free and open source (GPL-3.0). Sponsoring on GitHub is welcome, never required
