What to expect from PNG compression

PNG is lossless and supports transparency, which makes it useful for logos, screenshots and graphics. It can also be larger than JPG or WebP.

For the smallest result, try WebP output. For transparency or pixel-perfect graphics, compare PNG and WebP before downloading.
