- ZIP Shrinker is a browser tool that reduces ZIP file sizes by re-compressing files with higher compression using libdeflate, removing metadata, and removing directory entries.
- It uses WebAssembly to run libdeflate efficiently, achieving better compression than typical Deflate at the cost of more computation time.
- Removing unused metadata and directory entries (like empty directories) saves additional bytes, and the tool is backward-compatible with standard ZIP extractors.
- Testing showed savings of 5.62% on Linux source, 18.16% on an EPUB file, and 2.86% on a JAR file, demonstrating practical benefits for bandwidth and storage costs.
