| Measured fixture results | File reduction: 56.31% · Output size: 1807.8 KB | File reduction: 48.14% · Output size: 2146.1 KB |
| Fixture findings | Local processing reduced this fixture by about 56% with adjustable quantisation; useful if you want parameter control. | Exported full-size PNG with about 48% size reduction in this test; other files need separate tests. |
| Original historical observation | RedKetchup is one of the few tools that lets users manually pick 8-bit quantization dithering algorithms (Atkinson) and inspect pixels side-by-side in a full-screen viewer: it shrinks our 4.14 MB anchor PNG by 56.31% to 1.77 MB locally at PSNR=39.35 dB and SSIM=0.9984 (02_workspace.png, 03_download.png). | 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). |
| Suitable uses · historical assessment | Developers and UI designers who want fine-grained control over PNG color depth (8/24/32-bit) and dithering algorithms with 100% local browser privacy | Users who want a clean ad-free interface with post-compression online Preview and Re-edit capabilities |
