Examples

Photo for web

A 4MB DSLR photo compressed at 80% quality produces a file under 400KB that is visually identical at screen resolution.

Screenshot

A 1.2MB PNG screenshot compressed to WebP at 85% quality becomes around 200KB with no visible quality loss.

Product image

A 3MB product photo compressed at 75% quality produces a 250KB file that loads quickly in a browser without appearing blurry at standard display sizes.

Common Mistakes to Avoid

  • !Compressing an image that has already been compressed - each compression cycle on a lossy format like JPG adds quality loss
  • !Using too aggressive a quality setting for images with fine text or sharp lines - compression artefacts show up on edges first
  • !Compressing images for print use - print requires high resolution and should not be compressed below 300 DPI

Limitations

  • –Lossy compression (JPG, WebP) reduces file size by permanently discarding some image data. This cannot be undone.
  • –PNG compression is lossless, so the file size reduction is smaller compared to lossy formats
  • –Very small images (under 100KB) may not compress significantly further

Privacy

Image compression runs entirely in your browser. Your photos and images are never uploaded to any server. This is important for personal photos, confidential product images, or any image containing sensitive information.

Frequently Asked Questions

Does compressing an image reduce quality?

Lossy compression (JPEG) slightly reduces quality at high compression ratios. PNG uses lossless compression so quality is preserved.
