About Image Optimizer

The Image Optimizer is a free online tool that compresses PNG, JPG and WebP images to reduce their file size without a perceptible loss in visual quality. Since images are typically the largest contributors to web page weight, optimizing them is one of the highest-impact improvements you can make for page speed, Core Web Vitals and user experience.

Google's PageSpeed Insights and Lighthouse audits frequently flag unoptimized images as a top issue. This tool applies lossless or lossy compression algorithms to significantly reduce image size — often achieving 50–80% reductions.

How to Optimize Images

  • Upload your image file (JPG, PNG or WebP)
  • Choose compression level: Lossless (no quality loss) or Lossy (smaller file, slight quality tradeoff)
  • Click Optimize
  • Compare before/after file sizes and download the optimized image

Why Image Optimization Matters

  • Faster page loads improve user experience and reduce bounce rate
  • Google uses page speed as a ranking factor
  • Smaller images reduce bandwidth costs for your hosting
  • Critical for mobile users on slower connections

For best results, resize images to their display dimensions before optimizing. Use WebP format where possible — it offers 25–35% better compression than JPG at equivalent quality. Free, no login, no watermarks.
