| 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. | No obvious artifacts appeared in this 2× test; recovery of fine blurred edges remained limited. |
| 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). | PSNR=27.34dB · SSIM=0.8924 (2x 1024×1024 JPG); Mode A GT exposes the underlying algorithm: edge_corr=0.5740 and hf_ratio=0.4018 sit barely above standard non-AI Bicubic interpolation (0.5656 / 0.3651), proving its 0.60s speed comes from a lightweight CNN/unsharp filter rather than deep super-resolution; Calibration plate PSNR=15.60dB: artifact-free, but recovers significantly less high-frequency edge detail than iLoveIMG or Upscale.media. |
| Suitable uses · historical assessment | Everyday users seeking login-free, true 4x (2048×2048) watermark-free native PNG exports with strong edge sharpness and text restoration | Users needing instant (0.6s), completely free no-login 2x JPG enlargement without deep high-frequency texture reconstruction |
| Result & output evidence | No native output obtained; the preview does not establish final export quality. | |

| 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). | 31 / 35 Zero paywalls or credit traps: unlike its paywalled Text-to-Image tool, Depositphotos' Upscaler is a 100% free utility exporting unwatermarked 1024×1024 JPGs with no login. |
