Free Online Image Compressor
Need to reduce image file size for faster website loading or email attachments? Our Image Compressor can reduce file sizes by 40-80% while maintaining visual quality. We show you the exact before/after sizes so you can see the savings.
How It Works
JPEG and WebP formats use "lossy" compression – they discard image data that's less noticeable to human eyes. At 70-80% quality, the visual difference is minimal, but file size drops dramatically.
Recommended Settings
- 80% Quality: Best balance – nearly indistinguishable from original.
- 60-70% Quality: Great for web images – significant size reduction.
- 40-50% Quality: Thumbnails and previews – smaller but noticeable artifacts.
- WebP Format: Modern browsers support this – 20-30% smaller than JPEG.
