Why PNG files get huge

PNG is lossless and ideal for logos, icons and screenshots with sharp edges. But for photographs, that losslessness means enormous files — JPG or WebP will be a fraction of the size with no visible quality loss.

How to shrink it

  • Photo in a PNG? Convert it to JPG with the tool below — expect 70-90% smaller.
  • Need transparency? Keep PNG but run it through the compressor, or convert to WebP which supports alpha at smaller sizes.

Tips

  • If the image has no transparent areas, JPG is almost always the right call.
  • Screenshots of text stay crisper as PNG; photos do not.
