What is a PNG file?

A PNG file is a raster image format that stands for Portable Network Graphics. Developed in the mid-1990s as a patent-free replacement for the GIF format, PNG has become one of the most widely used image formats on the web and in digital design.

PNG uses lossless compression, meaning no image data is discarded during compression, ensuring that images maintain their original quality. This makes PNG ideal for graphics with sharp edges, text, and areas of solid color, while also supporting full alpha channel transparency.

Technical Specifications

  • Lossless compression algorithm
  • Maximum dimensions: 2,147,483,647 × 2,147,483,647
  • Color depths: 1, 2, 4, 8, 16 bits per channel
  • Supports gamma correction

File Information

  • .png (standard extension)
  • MIME type: image/png
  • First released: October 1996
  • Current version: PNG 1.2 (1999)

Why Choose PNG Images?

PNG remains the gold standard for web graphics and digital design where image quality, transparency, and universal compatibility are essential. Its lossless compression ensures your graphics maintain perfect quality while providing features that make it indispensable for modern digital workflows.
