| Fixture findings | Under the 2048px standard anchor, BIRME's default preset exports a 512x512 native PNG file achieving 27.59 dB PSNR, 0.9755 SSIM, and 88.37% size reduction with pure client-side Canvas/Pica offline processing in 342ms. | Strong size reduction suits upload limits; gradients show banding and download ads need care. |
| Original historical observation | BIRME executes purely in local browser Canvas with Pica interpolation, reducing 4.14 MB to 481.4 KB (-88.4%) while preserving PNG format and transparency in 342ms. | 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 | E-commerce and web operations requiring fast batch resizing and compression while preserving PNG transparency | 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 |
