| Measured fixture results | File reduction: 56.5% · Output size: 1800.1 KB | File reduction: -42.27% · Output size: 5886.7 KB |
| Fixture findings | Over 50% size reduction while preserving 2048px resolution and transparency; solid quality and easy to use. | Default settings increased this PNG's size; downloading also required login. |
| Original historical observation | Aconvert processes compression on cloud servers, reducing the 4.14 MB anchor by 56.5% to 1.80 MB under default Lossy 80 while maintaining SSIM 0.9966 and preserving micro-textures. | Fotor's Image Compressor exposed two major flaws in real-machine testing: first, its default 'Format: Original / Image Quality: Medium' mode has no PNG palette quantizer, causing our 4.0 MB PNG to balloon to 5.7 MB (`↑ 42.3%` in red on Fotor's own card, 02_workspace.png); second, clicking Download immediately hits a mandatory login wall (03_download.png). |
| Suitable uses · historical assessment | Users and webmasters needing fast free image compression while preserving transparency and 2048px original resolution | Only usable for signed-in Fotor users compressing JPEGs (or converting PNGs to JPG/WebP); completely unsuitable for native PNG compression |
