About PNG Files

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF and supports a variety of transparency options and color depths.

Key PNG Features

PNG offers several advantages for web developers and designers looking for high-quality images with transparency:

Technical Details About PNG

PNG uses DEFLATE compression, a combination of LZ77 and Huffman coding
PNG files are organized in chunks, each with specific functions (IHDR, PLTE, IDAT, IEND)
PNG supports multiple color types: grayscale, indexed color, RGB, and variants with alpha transparency
PNG is perfect for images with sharp edges, text, and transparency like logos and illustrations
Unlike JPEG, PNG uses lossless compression, preserving all image data
PNG uses adaptive filtering to improve compression efficiency before applying DEFLATE
PNG can be optimized further with specialized tools that recompress the data more efficiently

Browser Compatibility

PNG format has excellent cross-browser support:

Note: While PNG is universally supported in modern browsers, WebP typically offers better compression for the same visual quality.
