| Measured fixture results | Tested scale: 4× | Tested scale: 2× |
| Fixture findings | 4x upscaling of the 512×512 anchor to a native 2048×2048 PNG achieved 27.42 dB PSNR, 0.8876 SSIM, 0.6652 edge_corr, and 16.23 dB calibration plate PSNR with crisp lettering and line pairs. | Downloaded a watermark-free 1024px image; the preview watermark was absent from the saved file. |
| Original historical observation | Uploading the 512×512 degraded anchor without login and selecting 4x produced a native 2048×2048 watermark-free PNG in 7.49s server time (PSNR = 27.42 dB, SSIM = 0.8876, edge_corr = 0.6652, plate_psnr_db = 16.23 dB) with sharp wooden sign text and micro calibration lines (02_workspace.png, 03_download.png). | Aiseesoft Image Upscaler Online displays a preview watermark to prevent right-click scraping but honors its caption 'After saving, the image has no watermark': clicking Save exports a clean 1024×1024 PNG scoring PSNR = 27.03 dB and sign ROI PSNR = 30.32 dB. |

| Pricing transparency | 32.5 / 35 The landing page (01_landing.png) and pricing page clearly disclose free quotas (2 daily free guest credits without login, plus 5 bonus credits for new registered accounts) and credit costs (1 credit for 2x, 2 credits for 4x); in our no-login test, selecting 4x on the 512×512 anchor consumed 2 guest credits and exported a 2048×2048 watermark-free native PNG directly (02_workspace.png, 03_download.png). | 29.5 / 35 While the workspace preview displays diagonal watermark text, a note directly beneath the preview states 'After saving, the image has no watermark.' Clicking Save immediately exports a clean, 100% watermark-free 1024×1024 PNG without login (02_workspace.png, 03_download.png). |
