| Measured fixture results | File reduction: 57.73% · Output size: 1749 KB | File reduction: 0% · Output size: 4137.9 KB |
| Fixture findings | Kept PNG format while reducing this fixture by about 58%; check free file-size and quantity limits. | The roughly 4MB fixture exceeded the recorded 1MB free limit; free compression could not complete. |
| Original historical observation | TinyPNG remains the gold standard for smart PNG quantization: without changing format or pixel dimensions (2048×2048), it cuts our 4.24 MB anchor PNG by 57.73% (1,749.0 KB) while achieving the highest fidelity in the category at PSNR=40.09 dB and SSIM=0.9987 (02_workspace.png, 03_download.png). | 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). |
| Suitable uses · historical assessment | Frontend developers, UI designers, and content editors who need to keep native PNG format (and alpha support) while cutting file weight by ~60% with virtually zero visual loss (PSNR > 40 dB) | Only usable for tiny web icons/thumbnails already under 1 MB, or enterprise developers with a paid Kraken.io PRO API subscription |

| Pricing transparency | 33 / 35 Clearly states free tier limits on the upload dropzone ('Up to 20 images, max 5 MB each'). Uploading the 4.24 MB (2048×2048) anchor PNG requires no login and immediately provides a free download button (01_landing.png, 02_workspace.png, 03_download.png). | 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). |
| Interaction restraint | 27.5 / 30 No forced sign-up modal, no countdown gates, and no watermark traps; clicking Download immediately exports the compressed PNG. | 21 / 30 No fake download ads, but steps 1, 3, and 4 (URL Paster, Image Resizing, Image Conversion) are locked behind 'available in Kraken.io PRO' and any file over 1 MB fails with a PRO upgrade prompt (03_download.png). |

| Deliverable specifications | 20 / 20 Exports a watermark-free 2048×2048 PNG without login (capped at 5 MB per file and 20 files/day on the free tier) (19.0/20) | 7.7 / 20 Free tier is restricted to files ≤1 MB, preventing free export of standard high-resolution PNG/JPG images (7.7/20) |
