About PNG compression
PNG is lossless, which keeps images sharp but makes files large. A PNG can only get smaller by reducing its dimensions or switching to a more efficient format.
With Automatic output, Fylix keeps your file as PNG when it already fits and otherwise saves it as WebP, which supports transparency and is usually much smaller. Choose PNG as the output format if you must keep PNG.
