What is a PNG file?

Portable Network Graphics (.png)

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free alternative to GIF. PNG uses DEFLATE lossless compression, meaning images retain 100% of their original quality regardless of how many times they're saved. The format supports 8-bit (256 colors) and 24-bit (16.7M colors) color modes, plus a full 8-bit alpha channel for smooth transparency and semi-transparency effects. PNG is the preferred format for screenshots, logos, icons, UI elements, diagrams, and any image requiring sharp edges or transparency. PNG files are typically larger than JPG for photographs but significantly better for graphics with text, solid colors, or transparency. PNG also supports interlacing for progressive loading, gamma correction for cross-platform color consistency, and embedded text metadata. Modern alternatives like WebP and AVIF offer better compression, but PNG remains the gold standard for lossless quality.
