Why Compress Images?

Large images slow down websites and hurt Google PageSpeed scores. Compressing images is one of the highest-impact optimizations available. At 80% quality, images are virtually indistinguishable from originals at roughly half the file size. Use our image optimizer before uploading to WordPress, Shopify, Squarespace, or any CMS.

Tips for Best Results

  • Use 80% quality for web images — near-original quality at half the size
  • Convert PNG photos to JPG for much smaller files
  • Use WebP format for the best compression (30% smaller than JPG)
  • Use Target Size mode for government/form portals requiring exact file sizes
  • Always compress before uploading to WordPress, Shopify, or any website platform
