Why convert HEIC to AVIF?

HEIC is an Apple-first container that Windows and most browsers won't preview. AVIF keeps the same modern compression benefits but is supported natively across Chrome, Firefox, Safari and Edge, making it the right choice when the photo is heading to a website.

How it works

Drop your HEIC file above and Morphix decodes it locally, then re-encodes it as AVIF using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
