🔁 Convert JPG to AVIF
About these formats
About JPG. JPG (JPEG) is a lossy format tuned for photographs. It produces small files and opens on practically every device and app ever made, but it cannot store transparency and re-saving repeatedly slowly degrades quality.
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 JPG (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 JPG as a master copy.
