| Measured fixture results | File reduction: 49.63% · Output size: 2084.2 KB | File reduction: 9.52% · Output size: 3744 KB |
| Fixture findings | Reduced this fixture by about 50% with detail retained; avoid the sidebar ad resembling a download button. | Default PNG preserved quality but reduced this fixture by only about 10%; other export formats are available. |
| Original historical observation | ResizePixel delivers remarkable quality in Auto (keep the quality) mode: shrinking our 4,137.9 KB PNG by 49.63% to 2,084.2 KB in 7.6s while maintaining a near-lossless 43.94 dB PSNR and 0.9994 SSIM (02_workspace.png). Users just need to ignore the green 'DOWNLOAD EXTENSION' ad on the left and click the real 'Go to Download / Download Image' button at the bottom right (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 | Users who demand near-lossless visual quality (43.94 dB PSNR) or need to shrink an image to an exact KB ceiling for government/exam portals | Users wanting free no-login near-lossless PNG optimization (48.20 dB PSNR) or one-click conversion to WebP/AVIF/JXL |
