Best Image Formats for 20KB Compression
Different file formats affect compression results:
| Format | Best Use Case | Compression Ability |
|---|---|---|
| JPEG | Photos, social media | Best for small file size |
| PNG | Graphics, logos | Supports transparency but larger files |
| WebP | Web optimization | Better compression than JPEG & PNG |
| GIF | Animated images | Smallest file size, but limited colors |
💡 Pro Tip: WebP format gives the best results for online image optimization with a smaller size than JPEG & PNG.
Additional Tips for Compressing Images to 20KB
✅ Crop Unnecessary Areas – Remove extra white space to reduce size.
✅ Reduce Image Dimensions – A smaller image (e.g., 600×400) is naturally smaller in file size.
✅ Use JPEG Instead of PNG – JPEG images are more compressible than PNGs.
✅ Lower DPI (Dots Per Inch) – Reducing DPI from 300 to 72 can cut the file size significantly.
