How to compress PNG files effectively

PNG is ideal for transparency, logos, UI screenshots, icons, and clean graphics. It is not always the smallest format for photos. If your PNG contains a photo and the target site does not require transparency, converting to JPG or WebP can reduce the file much more while keeping the image visually acceptable.

Best PNG settings

  • Use PNG for transparency and sharp graphics
  • Use JPG for normal photos
  • Use WebP for modern compact files
  • Reduce max width if the PNG remains too large
