| Measured fixture results | File reduction: 78.39% · Output size: 894.2 KB | File reduction: 79.65% · Output size: 842 KB |
| Fixture findings | Shrinks the 4.14 MB standard PNG by 78.39% to 894.2 KB in native PNG format at 31.12 dB PSNR and 0.9896 SSIM. | Strong size reduction suits upload limits; gradients show banding and download ads need care. |
| Original historical observation | Aiseesoft Free Image Compressor shrinks the 4.24 MB (2048×2048) anchor PNG down to 894.2 KB (-78.39%, 4.63× ratio) without login, preserving native PNG dimensions at PSNR=31.12 dB and SSIM=0.9896. | 11zon offers a very handy dual-tab interface ('Slider' by % and 'Size' by target KB), shrinking our 4.14 MB PNG down to 842 KB (-79.65%) in 1.8s at its default 60% level; however, the aggressive palette cut causes visible gradient banding (PSNR=32.83 dB) and users must dodge 3 green 'DOWNLOAD EXTENSION' fake ad buttons (02_workspace.png). |
| Suitable uses · historical assessment | Users looking for high-ratio (-78%) no-login PNG compression on files under 5 MB without creating an account | Users facing strict government or academic portal upload limits (e.g., forcing a large PNG under 1 MB or an exact KB target) who can tolerate mild background gradient banding |
