About PNG format

PNG is a lossless image format that supports transparency, making it ideal for web graphics, logos, and images requiring crisp edges.

  • +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
