🔁 Convert HEIC to AVIF
About these formats
About HEIC. HEIC is the high-efficiency format iPhones use by default. It stores good quality in small files, but it is an Apple-centric format that much non-Apple software and many websites cannot open.
About AVIF. AVIF is one of the most efficient image formats, often noticeably smaller than WebP or JPG at the same visual quality, with transparency support. Support is good in current browsers but not yet universal across older devices and apps.
Going from HEIC (lossy raster) to AVIF (lossy or lossless raster) keeps your picture intact while moving to a format that can also store transparency if you need it later.
When to keep the original instead. There is no quality penalty to worry about here, but it is still wise to keep the original HEIC as a master copy.
