| Measured fixture results | File reduction: 48.14% · Output size: 2146.1 KB | File reduction: 88.37% · Output size: 481.4 KB |
| Fixture findings | Exported full-size PNG with about 48% size reduction in this test; other files need separate tests. | 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. |
| Original historical observation | 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). | 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. |
