Modern browsers support lighter, more efficient formats than JPEG or PNG — our Image Compressor converts your image to one that loads faster with no visible quality trade-off.

Use Cases

  • Converting legacy images to a modern format for a website rebuild

  • Preparing assets that take advantage of next-gen browser format support

  • Serving smaller files to visitors on slower mobile connections

Tips & Best Practices

  • Modern formats like WebP and AVIF are 25-50% smaller at equivalent visual quality
  • Every major browser released in the last few years supports these formats
  • Smaller assets mean a faster Time to Interactive for every visitor
  • Keep a JPEG/PNG fallback only if you specifically need to support very old browsers
