Animated PNG plays fine in a browser but not in most chat apps, which still expect GIF. Filemorph converts APNG to GIF on your iPhone.

APNG (animated PNG) supports more colors and better transparency than GIF, which is why some tools export animations that way, but support outside browsers is inconsistent — most messaging apps, forums and older tools still only understand animated GIF.
Filemorph decodes each frame of the APNG using ImageIO and re-encodes the sequence as an animated GIF with matching frame timing. Because GIF is limited to 256 colors per frame, images with smooth gradients or soft transparency edges can show some banding or a hard edge where the APNG had a soft one.
In the app: Convert → APNG → GIF.
GIF is the animated format nearly everything still supports, while APNG's support outside browsers is patchy. Convert to GIF whenever the animation needs to play in a chat app, forum or tool that does not recognize APNG.
Yes. Unlike web converters that upload your files to a server, Filemorph converts every file locally using Apple's frameworks. Nothing leaves your device, and it works with no internet connection. This conversion is in the free tier.
Yes, Filemorph carries over each frame's duration and the loop count from the source APNG.
GIF only supports fully transparent or fully opaque pixels, no partial transparency, so any soft, semi-transparent edges in the APNG become hard edges in the GIF.
