How to optimize & reduce bit-depth of PNGs#

Optimizing PNGs with oxipng#

PNG optimization refers to losslessly compressing PNG images, which reduces the file size of PNGs with zero loss in quality.

Screenshots taken with some programs compress more than others — see the Statistics page for details.

The recommended tool to optimize PNGs is oxipng, a cross-platform tool written in Rust.
