Why does the first conversion take a moment?

The HEIC decoder and AVIF encoder add up to about 4 to 5 MB of WebAssembly that loads on first use. After that it's cached and conversions are fast.

How does AVIF compare to HEIC?

Both are modern, efficient codecs. AVIF opens in any modern browser with no plugins. HEIC is still mostly Apple-only.

HEIC to AVIF

Re-encodes iPhone HEIC with AV1 into AVIF, usually smaller than JPG at the same quality.

What this does

This decodes each iPhone HEIC photo in the browser and re-encodes the pixels as AVIF using the AV1 codec. At a matched quality, AVIF usually lands smaller than JPG, and unlike HEIC it opens in any modern browser without a plugin.
