Why image size matters

Large images slow down websites and eat into mobile data. A 4MB photo can usually be compressed to under 400KB with no visible quality loss — a 90% reduction that makes pages load 3–5× faster.

How to compress images in your browser

  1. Go to ToolCrix Image Compressor.
  2. Drop your JPG, PNG or WebP files (batch supported).
  3. Adjust the quality slider (80% is a good starting point for photos).
  4. Download individually or as a ZIP.

JPG vs PNG vs WebP

  • JPG — best for photos. High compression, tiny file size.
  • PNG — best for logos and images with transparency.
  • WebP — best for websites. 25–35% smaller than JPG/PNG with similar quality.

Tips for maximum compression

  • Resize before compressing — a 4000px photo displayed at 800px needs to be no bigger than 800px.
  • Convert PNG photos to JPG for much smaller files.
  • Use WebP for web assets — supported in all modern browsers since 2020.
