Tested result & sample
At its default Quality = 90% setting while keeping PNG format, TinyWow applies conservative quantization that preserves near-lossless pixel fidelity (PSNR 48.20 dB, SSIM 0.9996) with a modest -9.52% byte reduction; switching the output dropdown to .webp or .avif yields much larger savings.
