Pro Image Compression Tips
WebP: Start at 75–85% quality. AVIF: 60–80% is often plenty for great results.
Need transparency? Prefer PNG or lossless WebP. JPEG flattens backgrounds.
Keep UI/Text crisp with lossless PNG/WebP. Use lossy WebP/AVIF for standard photos.
Strip EXIF/ICC metadata under Advanced Settings to shave off another 5-15%.
