libpng is the official PNG reference library. It supports almostall PNG features, is extensible, and has been extensively tested forover 23 years. The home site for development versions (i.e., may bebuggy or subject to change or include experimental features) is https://libpng.sourceforge.io/, andthe place to go for questions about the library is the png-mng-implement mailing list.
libpng is available as ANSI C (C89) source code and requires zlib 1.0.4or later (1.2.5 or later recommended for performance and securityreasons). The current public release, libpng 1.6.37, fixes the use-after-freesecurity vulnerability noted below, as well as an ARM NEON memory leak in thepalette-to-RGB(A) expansion code (png_do_expand_palette()).
The portability notice should not come as a particular surpriseto anyone who has added libpng support to an application this millenium; themanual has warned of it since at least July 2000. (Specifically:'Starting with version 2.0.0, both structures are going to be hidden, andthe contents of the structures will only be accessible through thepng_get/png_set functions.' OK, so the version number was off abit...and the grammar, too, but who's counting?) Those whose apps depend onthe older API need not panic, however (for now); libpng 1.2.x continues toget security fixes, as has 1.0.x for well over a decade. (Greg no longerbothers to list either series here; enough's enough, folks. Update thoseapps now!)
The 1.5.x and later series also include a new, more thorough test program(pngvalid.c) and a new pnglibconf.h header file thattracks what features were enabled or disabled when libpng was built. Onthe other hand, they no longer internally include the zlib.h headerfile, so applications that formerly depended on png.h to providethat will now need to include it explicitly.Complete differences relative to libpng 1.4.xare detailed here.
See the bottom of this page for warnings aboutsecurity and crash bugsin versions up through libpng 1.6.31.
In addition to the main library sources, all of the 1.2.x/1.4.x/1.5.x/1.6.x/1.7.x series includethe rpng, rpng2 and wpng demo programs,the pngminus demo program, a subset of Willem van Schaik'sPngSuite test images,and Willem's VisualPng demo program.

The release before that fixed another bug, this one in the PNG-writing code:
Finally--and most important--there were several security vulnerabilitiespresent in versions of libpng prior to 1.2.6 and 1.0.16, one of which isquite dangerous:
