This pure Ruby library can read and write PNG images without depending on an external image library, like RMagick. It tries to be memory efficient and reasonably fast. It supports reading and writing all PNG variants that are defined in the specification, with one limitation: only 8-bit color depth is supported. It supports all transparency, interlacing and filtering options the PNG specifications allows. It can also read and write textual metadata from PNG files. Low-level read/write access to PNG chunks is also possible. This library supports simple drawing on the image canvas and simple operations like alpha composition and cropping. Finally, it can import from and export to RMagick for interoperability. Also, have a look at OilyPNG at https://github.com/wvanbergen/oily_png. OilyPNG is a drop in mixin module that implements some of the ChunkyPNG algorithms in C, which provides a massive speed boost to encoding and decoding.
PNG is an almost-pure-ruby PNG library. It lets you write a PNG without any C libraries.
This Ruby C extenstion defines a module that can be included into ChunkyPNG to improve its speed.

PngConform provides a comprehensive PNG, MNG, and JNG file validation library in pure Ruby. It validates file structure, chunk validity, CRC checksums, zlib compression, and profile conformance. Built with a layered architecture using BinData for binary parsing, Lutaml::Model for domain models, and Thor for CLI. Supports PNG baseline, MNG-VLC, MNG-LC, and JNG profiles with detailed validation reporting compatible with pngcheck output.
