The "mango" lib [1] claims to be even faster for PNGs. Actively maintained but doesn't have as much buzz, I think the devs haven't advertised it as much on places like this.

Also, it has the funniest testimonials.

Speed isn't the only thing that matters; is mango as safe as wuffs in the face of untrusted input?
