Why WebP is great for the web
WebP typically produces files 25-35% smaller than JPEG at the same visual quality, and it supports transparency like PNG. That makes it ideal for websites that need to load fast and pass Core Web Vitals.
Lossy vs lossless WebP
WebP can be lossy (best for photos) or lossless (best for graphics). Aimager uses the quality slider to control lossy encoding; lower values mean smaller files. Preview the comparison slider to find your sweet spot.
