| Measured fixture results | File reduction: 50.8% · Output size: 2035.9 KB | File reduction: 9.52% · Output size: 3744 KB |
| Fixture findings | Reduced this fixture by about 51% without manual settings; findings cover this image test only. | Default PNG preserved quality but reduced this fixture by only about 10%; other export formats are available. |
| Original historical observation | Powered by Neuxpower's mature NXPowerLite engine, WeCompress requires zero manual tuning to cut our 4.14 MB anchor PNG by 50.80% to 2.04 MB while maintaining PSNR=39.65 dB and SSIM=0.9985 (02_workspace.png, 03_download.png). | 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. |
| Suitable uses · historical assessment | Office users who prefer a zero-configuration workflow for compressing large images (≤50 MB) alongside PDF, PowerPoint, Word, and Excel files | Users wanting free no-login near-lossless PNG optimization (48.20 dB PSNR) or one-click conversion to WebP/AVIF/JXL |
