| Measured fixture results | File reduction: 65.65% · Output size: 1421.6 KB | File reduction: 79.65% · Output size: 842 KB |
| Fixture findings | Substantial 65.7% size reduction while fully preserving 2048px resolution and transparency without visual artifacts; fast and straightforward. | Strong size reduction suits upload limits; gradients show banding and download ads need care. |
| Original historical observation | Uploading the standard 4.14 MB PNG anchor (anchor_compress_v1) to YouCompress (https://www.youcompress.com/images/) completed in 4.27s on cloud servers, displaying Completed: Download (4.04MB => 1.39MB, -65.65%), exporting a 1,421.6 KB PNG preserving 2048x2048 resolution, transparency, PSNR 34.97 dB, and SSIM 0.9956. | 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 | Not verified | 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 |
