libpng is the official Portable Network Graphics (PNG) reference library (originally called pnglib). It is a platform-independent library that contains C functions for handling PNG images. It supports almost all of PNG's features, is extensible, and has been widely used and tested for over 18 years. libpng is dependent on zlib for data compression and decompression routines.

libpng is released under the libpng license, a permissive free software licence, and is free software. It is frequently used in both free and proprietary software, either directly or through the use of a higher level image library.
