The STB PNG decoder is very fast, quite a bit faster than LodePNG (approx 2x according to benchmarks I've seen). It's also widely used, so should receive plenty of testing. And the license is very permissive/PD.

Does it support everything LodePNG does, though? We'd have to investigate.

libspng looks like another interesting candidate. According to its own documentation it's both faster, more secure (fuzzing regime and test cases) and more versatile (progressive loading etc) than the alternatives.
