WebP compared with AVIF
WebP is a web-focused raster format with efficient lossy compression and alpha transparency.
AVIF offers efficient modern compression and alpha transparency, although older software may not open it.
Quality, compression and transparency
AVIF uses adjustable lossy compression in this converter. Higher quality usually retains more detail and increases file size. Transparent pixels decoded from WebP can remain transparent through the alpha channel, and the original pixel dimensions are preserved.
