About:
Libpng is the official reference library for the Portable Network Graphics (PNG) format. It provides functions for reading, writing, and manipulating PNG image files, including support for transparency and various compression levels. As a foundational dependency, it is widely used by graphics software and web browsers to ensure efficient and lossless image processing.
Key Features:
  • Full support for PNG specification
  • Lossless data compression
  • Transparency handling (alpha channel)
  • Platform-independent C library
Use Cases:
  • Decoding PNG images in web browsers and applications
  • Encoding images to the PNG format for web graphics
  • Manipulating image metadata and color types
Alternatives:
  • libjpeg – Focuses on lossy JPEG compression rather than lossless PNG
  • libtiff – Targeted at high-quality archival images, often larger than PNG
