| Format | Compression | Browser Support | Best Use Case |
|---|---|---|---|
| JPEG | Good (lossy) | Universal | Photos, complex images |
| PNG | Fair (lossless) | Universal | Graphics, transparency |
| WebP | Excellent | Modern browsers | Web optimization |
| AVIF | Best | Latest browsers | Next-gen web |
AVIF typically offers the best compression ratios, followed by WebP and JXL. However, the "best" format depends on your specific needs including browser support, image content, and quality requirements.
WebP typically provides 25-35% better compression than JPEG with similar quality. Use WebP for modern web applications, but provide JPEG fallbacks for older browsers. Our tool helps you visualize the exact differences.
For web images, 75-85% quality usually provides the best balance. For print or high-quality displays, use 90-95%. Our tool lets you test different quality levels to find your optimal setting.
Yes! Adjust the quality slider to test different compression levels across all formats simultaneously. You can also zoom in to inspect compression artifacts and quality variations in detail.
For web use, we recommend WebP for modern browsers with JPEG fallback for older browsers. AVIF offers even better compression but has limited support. PNG is ideal for images requiring transparency or when lossless quality is essential.
