The PNG Format: Quality Without Compromise
The Portable Network Graphics (PNG) format was designed as an improved, non-patented successor to the GIF format. Its main feature is lossless compression, meaning no pixel data is discarded during saving, maintaining perfect sharpness for logos, graphics, and screenshots.
