AVIF is one of the newest image formats browsers use for faster page loads, but plenty of apps and older devices still cannot open one. Filemorph converts AVIF to JPG on your iPhone, no upload required.

Save an image from a modern website and you increasingly get an AVIF file — a format built for smaller downloads, not compatibility. It works great in a browser but stalls the moment you try to open it in an older photo editor, attach it somewhere that does not recognize it, or hand it to someone on an older device.
Filemorph decodes the AVIF using ImageIO's AV1 image decoder and re-encodes it as a standard JPG that opens in essentially anything. Color and orientation are preserved from the original.
In the app: Convert → To JPEG.
JPG is the format with the widest possible compatibility — every app, every device, every version of every OS. Convert to JPG whenever an AVIF you saved from the web needs to go somewhere that might not support the newer format.

AVIF is newer than JPG and PNG, and support varies across apps and older devices. Converting to JPG sidesteps that entirely.

Yes, it is part of Filemorph's free tier.
