Frequently asked
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.
