Comparison of text image compression

I've compared mozjpeg, webp, jpeg2000 (openjpeg & an proprietary encoder), jpeg-xl and avif with a text-like image containing circles with different width and tint.

See comparison-2022-11

The generated 920×920 px images (with different noise levels) are compressed with

/opt/mozjpeg/bin/cjpeg -quant-table 4 -q 75
