| Measured fixture results | File reduction: 49.74% · Output size: 2079.8 KB | File reduction: 79.65% · Output size: 842 KB |
| Fixture findings | Reduces the standard PNG by 49.74% in native PNG format at 38.19 dB PSNR and 0.9979 SSIM with virtually lossless detail. | Strong size reduction suits upload limits; gradients show banding and download ads need care. |
| Original historical observation | Nero AI Image Compressor shrinks the 4,237,170-byte (2048×2048) anchor PNG to 2,129,766 bytes (-49.74%) in High mode while maintaining native PNG format and 38.19 dB PSNR / 0.9979 SSIM. | 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 already in the Nero AI ecosystem who want high-PSNR (38.19 dB) PNG compression up to 50 MB / 16 MP with adjustable High/Low/Custom levels | 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 |
