PNG

Portable Network Graphic

Portable Network Graphics (PNG) stores raster images with lossless compression, preserving every pixel detail exactly. Unlike its predecessor GIF, PNG supports full alpha transparency and millions of colors, making it ideal for web graphics, logos, screenshots, and images requiring text overlays. Its patent-free design ensures broad compatibility across browsers and image editors.

Tips

Get a Better Resize Result

Do

  • Keep proportions on to avoid stretching.
  • Pick a size that matches where the image will be used.
  • Keep a copy of the original PNG file.

Avoid

  • Changing width and height separately: faces and shapes get distorted.
  • Shrinking the same image again and again.
  • Starting from a low-quality copy: use the original file.
