PSA: Use ZopfliPNG to compress your PNG assets

  Zopfli Compression Algorithm is a compression library programmed in C to perform very good, but slow, deflate or zlib compression.

  

I'm making a 2D game with lots of PNG assets. I recently found that ZopfliPNG regularly reduces the sizes of my assets by ~3x compared to Asesprite's output. I've tried a few other PNG compression tools, but ZopfliPNG consistently outperforms the others.

Have you tried Squoosh to find the best compression settings visually? I'd be very curious to see how they compare.

Did you compare to PNG crush and optipng? Those are what I used to use because they're easily installable Linux/brew packages.
