| Measured fixture results | File reduction: 88.94% · Output size: 457.6 KB | File reduction: 0% · Output size: 4137.9 KB |
| Fixture findings | Default 70% quality compresses 4.14 MB originals down to 458 KB (9× ratio) with 0.9973 SSIM, cleanly preserving text and specular highlights. | The roughly 4MB fixture exceeded the recorded 1MB free limit; free compression could not complete. |
| Original historical observation | Photopea client-side exports 2048×2048 compressed JPG, slashing size by 88.94% (4.14 MB → 457.6 KB) while sustaining 37.07 dB PSNR and 0.9973 SSIM. | Kraken.io's free Web Interface remains stuck in a decade-old '1 MB max file size' quota (01_landing.png): when fed our 4,137.9 KB (2048×2048) benchmark PNG, the queue immediately rejects it with 'File size too large. Upgrade to PRO and get 32MB max file size.' (02_workspace.png, 03_download.png). |

| Pricing transparency | 21 / 35 Discloses 'Free Web Interface has a file size limit of 1MB' in small gray footer text below the dropzone (01_landing.png); however, capping a 'Free Online Image Optimizer and Compressor' at 1 MB blocks almost every real-world high-res PNG/JPG that actually needs compression, immediately prompting 'File size too large. Upgrade to PRO and get 32MB max file size.' (02_workspace.png, 03_download.png). | |
