| Fixture findings | Retained original PNG format and alpha channel, scoring 30.58 dB PSNR and 0.9879 SSIM with clean metallic texture and no artifacts. | Default PNG preserved quality but reduced this fixture by only about 10%; other export formats are available. |
| Original historical observation | Uploaded 4.04 MB (4,137.9 KB) test image; under default smart compression, cloud processing completed in 5.99 seconds yielding 899.41 KB deliverable (78.26% reduction). Micro-details remained unblurred, with 30.58 dB PSNR and 0.9879 SSIM; provides interactive before/after slider with one-click download. | 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. |
