Higher = sharper but larger (PNG is lossless, no slider needed)
Frequently asked questions
AVIF compresses even better, but some older browsers, image viewers and editors still can't open it. WebP strikes a safer balance between small size and wide support.
Both decode then re-encode, and image cat uses high-quality settings, so for ordinary images the difference is barely visible. For true lossless, choose PNG instead.
