Libspng

Continuously fuzzed via OSS-Fuzz and written per CERT C standards, ensuring no known security bugs, which is critical for secure applications.

Provides straightforward functions like spng_decode_image, reducing complexity compared to libpng's verbose interface, as shown in the usage example.

Outperforms libpng in common use cases while maintaining correctness, evidenced by performance benchmarks in the README.

Can be built with miniz instead of zlib, reducing external dependencies and easing integration in constrained environments.

Supports all standard PNG chunks, gamma correction, and stream decoding, covering most PNG needs as per the features table.
