软件包摘要
Optimizer for PNG files
历史
项目历史与用法
Pngcrush is a command-line optimizer that losslessly reduces PNG files by trying combinations of PNG filters and zlib compression settings; it can also remove, preserve, or add ancillary chunks.
项目历史
Glenn Randers-Pehrson created pngcrush as a command-line PNG optimizer in the PNG and MNG Tools project. Its central design repeatedly compresses image data using different PNG filters and zlib settings, retaining the smallest valid result.
The early 1.x line moved from registration-gated distribution to an open-source license and expanded from recompression into chunk editing, metadata operations, recovery of some malformed files, color reductions, and platform portability.
采用历史
pngcrush became part of the classic Unix PNG-optimization toolkit and has been packaged across numerous Linux, BSD, macOS, and Windows-oriented package collections. Its portability and scriptable interface make it suitable for build, publishing, and asset pipelines.
Its continued maintenance has followed libpng and zlib closely, incorporating new chunks, parser fixes, architecture optimizations, and changes needed to build against different library generations.
使用方式
Users run pngcrush on an input and output PNG, optionally selecting a compression method or a wider search. The default workflow preserves image pixels while seeking a smaller IDAT stream.
Additional options can remove unwanted ancillary chunks, add or rewrite metadata, repair certain CRC and structural errors, preserve timestamps, or overwrite through a temporary output file.
为什么软件包爱好者会关心
pngcrush exposes the search space behind lossless PNG compression: filters, Deflate levels, strategies, chunk handling, and optional brute-force trials. It appeals to package and release engineers who need deterministic pixel preservation and detailed control over the output datastream.
The project also illustrates the maintenance burden of long-lived native image tools, including bundled-versus-system libraries, format extensions, security fixes, and architecture-specific optimization.
时间线
- Early 1.x era: pngcrush began as Glenn Randers-Pehrson's PNG recompression utility.
- Version 1.2.0: Registration was removed and the project adopted an open-source license.
- Version 1.4.5: Recovery and color-analysis capabilities expanded.
- Version 1.7.0: Limited animated-PNG chunk preservation was added.
- Version 1.8: Performance controls and additional architecture optimizations were introduced.
Related projects
- OptiPNG was inspired by pngcrush and explores a similar lossless filter-and-compression search space with a different in-memory design and preset model.
- libpng and zlib are the core PNG and Deflate implementations maintained alongside or used by pngcrush.
- pngnq's official workflow recommends pngcrush as a second-stage lossless compressor after palette quantization.
