| Measured fixture results | File reduction: 57.73% · Output size: 1749 KB | File reduction: 48.14% · Output size: 2146.1 KB |
| Fixture findings | Kept PNG format while reducing this fixture by about 58%; check free file-size and quantity limits. | Exported full-size PNG with about 48% size reduction in this test; other files need separate tests. |
| Original historical observation | TinyPNG remains the gold standard for smart PNG quantization: without changing format or pixel dimensions (2048×2048), it cuts our 4.24 MB anchor PNG by 57.73% (1,749.0 KB) while achieving the highest fidelity in the category at PSNR=40.09 dB and SSIM=0.9987 (02_workspace.png, 03_download.png). | XConvert offers a remarkably clean, ad-free interface. Uploading our 4.14 MB anchor PNG completes edge compression in 7 seconds, exporting a 2.15 MB native PNG (-48.14%) at PSNR=38.55 dB and SSIM=0.9981 (02_workspace.png, 03_download.png). |
| Suitable uses · historical assessment | Frontend developers, UI designers, and content editors who need to keep native PNG format (and alpha support) while cutting file weight by ~60% with virtually zero visual loss (PSNR > 40 dB) | Users who want a clean ad-free interface with post-compression online Preview and Re-edit capabilities |
