Pros

  • +No quality loss - stores raw pixel data
  • +Simple format easy to process
  • +Native Windows support

Cons

  • -Very large file sizes
  • -No compression options
  • -Not suitable for web use

About PNG format

PNG is a lossless image format that supports transparency, making it ideal for web graphics, logos, and images requiring crisp edges. Developed as a patent-free alternative to GIF, PNG uses efficient compression while preserving every pixel of the original image. It's the go-to format for screenshots, graphics with text, and images where quality cannot be compromised.

Pros

  • +Lossless compression preserves image quality
  • +Full transparency support with alpha channel
  • +Excellent for graphics with sharp edges and text

Cons

  • -Larger file sizes than lossy formats like JPEG
  • -Not ideal for photographs
  • -No animation support (use APNG or GIF instead)
