aperçu
Print info and check PNG, JNG, and MNG files
historique
pngcheck is a long-lived command-line validator and structural inspector for PNG, JNG, and MNG files.
pngcheck began in the formative period of PNG. Its reconstructed repository history reaches 13 March 1995, although the earliest releases by Alexander Lehmann are missing. Development passed through Andreas Dilger and Greg Roelofs; Chris Lilley of the W3C took over in 2021. The modern pngcheck 4 series derives from version 3.0.3 and adds support for chunks introduced by later PNG editions, including animated PNG and content-credential data.
pngcheck has remained available across Unix, Windows, DOS, OS/2, Macintosh, and Amiga environments. It is packaged by Homebrew, Debian, Ubuntu, Fedora-family distributions, MacPorts, Nix, and openSUSE, reflecting its long-standing role as a small format-diagnostics utility.
pngcheck verifies chunk CRCs and decompresses image data to test integrity. It can print dimensions and bit depth, dump chunk-level metadata, inspect palettes and transparency, extract embedded text, and batch-check collections of images.
pngcheck is unusually close in age to PNG itself: its reconstructed history begins only six days after the format specification was finalized. It gives maintainers a low-level view of chunks, checksums, compressed image data, and metadata, making it useful for format debugging, test suites, damaged-file analysis, and package QA.
