PNG is a lossless raster image format that supports transparency. It was created as an improved, non-patented replacement for GIF and is the most widely used lossless image format on the web.
PNG uses DEFLATE compression (the same algorithm as ZIP files) applied to filtered image data. It supports 8-bit and 16-bit color depths, grayscale, indexed color, and full-color RGB/RGBA. The format stores images in chunks (IHDR, IDAT, IEND) and includes a CRC checksum for data integrity. PNG files begin with an 8-byte signature: 137 80 78 71 13 10 26 10.
PNG (Portable Network Graphics) is a lossless image format that supports transparency. It's ideal for web graphics, logos, and screenshots where you need crisp edges without quality loss.
Use PNG for graphics with text, logos, screenshots, or images needing transparency. Use JPG for photographs and complex images where smaller file size matters more than perfect quality.
Use PNG compression tools that optimize the DEFLATE compression and reduce the color palette. Tools like BriskTool's image compressor can reduce PNG files by 60-80% with minimal visible quality loss.
