On my 3,167 image corpus, which contains images from Kodak, Waterloo, qoi, Enrico, and others, QLIC matched JXL effort 9 file sizes while being 9x faster at encoding and decoding 30% faster.

There is also a web demo you can try at qlic.pages.dev and the benchmarks at qlic.pages.dev/benchmarks/

Independent benchmarking is also needed.
