| Measured fixture results | Tested scale: 2× | Tested scale: 4× |
| Fixture findings | Downloaded a watermark-free 1024px image; the preview watermark was absent from the saved file. | Text was clear in this 4× output; the free-credit image carried a brand watermark. |
| Original historical observation | 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. | PSNR=27.02dB · SSIM=0.8631 (4x 2048×2048 Prime model); outstanding edge_corr=0.7108, hf_ratio=0.7910, and plate_psnr=17.25dB with razor-sharp 'REALTEST 2026' and 'REALTEST 2048px GT' typography, though free-credit exports include a bottom-left Let's Enhance watermark. |
| Suitable uses · historical assessment | Users needing a no-login, watermark-free 2x image upscaler with high text fidelity | Print and design professionals who need ultra-crisp 4x–16x texture restoration and are willing to subscribe to remove the watermark |
| Result & output evidence | No native output obtained; the preview does not establish final export quality. | |

| Evaluation basis | ||
| Pricing transparency | 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). | 18 / 35 The home page (Screenshot ①) presents a drag-and-drop uploader that immediately redirects to `/signup` promising 'Get started with 10 images free' (Screenshot ④); signing in via Google grants 10 credits and unlocks Prime 4x (2048×2048), but the exported 2048×2048 JPG embeds a semi-transparent 'Let's Enhance .io' watermark in the bottom-left corner (Screenshot ③) that was not disclosed on the signup page. |
| Interaction restraint | 26 / 30 No signup or payment required for 2x (1024×1024) watermark-free saving; higher scales (4x / 6x / 8x) clearly indicate Upgrade. | 21 / 30 Uses an 'upload-first, signup-gate-second' funnel, though it preserves the uploaded image in the `/boost` queue after login; workspace is clean and ad-free. |
