75 is a good balance. Lower = smaller file. PNG is always optimized losslessly.

Lossless PNG optimization

OxiPNG rewrites the file with better compression settings without changing any pixel. Savings depend on how the PNG was saved; an already optimized PNG may not get smaller, and then your original is kept.

For photos saved as PNG, choosing WebP or JPG as the output format saves far more.
