FAQ
- What's the size savings vs PNG?
- Typically 30–80% smaller depending on image complexity. WebP at 85% quality is usually indistinguishable from PNG to the eye.
- Should I pick WebP or AVIF?
- AVIF typically produces 20–30% smaller files than WebP but is slower to encode. WebP has broader older-browser support. For modern sites, AVIF wins on size; WebP wins on compatibility.
- Are conversions lossy or lossless?
- By default both are lossy with a quality slider (0–100). You can also tick the lossless option if you need pixel-perfect output, though file sizes will be larger.
