Tips and Best Practices
- → WebP at quality 80 usually matches JPEG at quality 90 — try it for 30%+ file size savings.
- → Use the magnifier to inspect fine details in the before/after comparison.
- → For photographs, JPEG/WebP at 75-85 quality is usually indistinguishable from the original.
- → For images with text or sharp edges, PNG preserves crispness better than lossy formats.
