| Measured fixture results | File reduction: 56.31% · Output size: 1807.8 KB | File reduction: 59.02% · Output size: 1695.6 KB |
| Fixture findings | Local processing reduced this fixture by about 56% with adjustable quantisation; useful if you want parameter control. | Reduced the tested PNG by about 59% with automatic download and no login; other inputs remain untested. |
| 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). | iLoveIMG compresses our 4.24 MB (2048×2048) anchor PNG down to 1,695.6 KB (-59.02%) in 3.4s without login and triggers an automatic download at PSNR=34.64 dB and SSIM=0.9953 (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 need fast, no-login batch compression of high-resolution PNG/JPG images larger than 5 MB without paying or signing up |
