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.[1] 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. In 2017 a 21 years old bug was fixed.[2]
As of 2017[update] the latest versions in the 1.6.x and 1.5.x branches were considered as release versions, while 1.4.x, 1.2.x, and 1.0.x were considered as legacy versions getting only security fixes.[3] All vulnerability warnings and crash bugs are published on the main page.[1]
