What is PNG?

PNG was created in 1996 as a patent-free replacement for GIF. It compresses images losslessly, so every pixel is preserved exactly, no matter how often the file is saved.

PNG supports true color and full 8-bit alpha transparency, which allows soft, anti-aliased edges over any background. Animated PNG (APNG) is an extension supported by modern browsers.

When to use PNG

  • Screenshots and user-interface images with text
  • Logos, icons and graphics with sharp edges or flat colors
  • Images that need transparent backgrounds
  • Intermediate files you will edit again

Limitations

  • Photos saved as PNG are much larger than JPG, WebP or AVIF
  • No lossy mode in the standard format

Compatibility

Universally supported by browsers, operating systems and image editors.

Compared with other formats

  • JPEG / JPG: JPG is far smaller for photographs but has no transparency.
  • WebP: WebP lossless is typically smaller than PNG and also supports transparency.
