Image Compressor reduces the file size of your JPG, PNG, and WebP images without significantly sacrificing visual quality. Perfect for website optimization, email attachments, and saving storage space. Adjust the quality slider to find the perfect balance between file size and image quality — lower values mean smaller files but more compression artifacts.
Image Format Compression Comparison
| Format | Compression Type | Quality Range | Best Quality Setting |
|---|
| JPG | Lossy | 1-100 | 70-85% (good balance) |
| PNG | Lossless | Palette reduction | Keep original |
| WebP | Lossy | 1-100 | 75-90% (good balance) |
Tips for Best Results
- For JPG/WebP photos, 70-85% quality retains good visual quality while reducing file size by a significant amount
- For PNG graphics with few colors, try reducing to PNG-8 (256 colors) for significant savings
- Always keep the original file in case you need full quality later
- Lossy compression is not reversible — once compressed, the discarded data cannot be recovered
