O que é um arquivo .png?

PNG (Portable Network Graphics) is a lossless image format designed as an improved, non-patented replacement for GIF. It supports full-color images with transparency (alpha channel), making it perfect for logos, icons, screenshots, and web graphics. Unlike JPEG, PNG preserves every pixel exactly, so images never lose quality when saved multiple times. The tradeoff is larger file sizes compared to JPEG for photographs.
