Nice. I could see plugging this into GenAI interfaces generated on the go

For the usual case of DEFLATE-based formats (PNG, ZIP) and JPEG, ECT [1] is the best available tool; to my best knowledge it dominates the entire Pareto frontier in this area, beating Zopfli and ADVPNG/OUT for most cases. If this software is still being maintained, it would be a good choice to switch to ECT now.

Additionally a number of 'junk' files such as Thumb.db and .ds_store are deleted from ZIP files.

That's no longer lossless.

It shouldn’t be assumed lossless at any point, but metadata-preserving. They only use the word once in the doc, with regard to PDF.

I’m curious to know how this compares to other compression tools like brotli, zstd, and xz.

I guess I’ll have to include it in my own benchmarking suite I’m developing.
