AVIF (AV1 Image File Format) uses lossy or lossless encoding and is best for next-gen web images — royalty-free format with better compression than WebP and JPEG. HEIC (High Efficiency Image Container) uses lossy or lossless encoding and excels at Apple device photos — iPhone and Mac default format with excellent compression efficiency. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing.
