| Measured fixture results | Tested scale: 4× | Tested scale: 2× |
| Fixture findings | This guest run produced a watermark-free 4× image with structure retained; findings cover this fixture only. | Colours and facial features looked natural; the free trial output was 2× with a watermark. |
| Original historical observation | PSNR=27.50dB · SSIM=0.8900 (4x 2048×2048 unwatermarked PNG); edge_corr=0.6685, hf_ratio=0.4995, plate_psnr=16.22dB—one of the very few tools offering genuine 400% watermark-free exports to anonymous guests. | Smart Upscaler 3 delivers natural skin and hair tone fidelity (PSNR=26.21 dB, SSIM=0.9644) without harsh oversharpening halos, but restricts free demos to 2x (1024×1024) with a watermark—contrasting sharply with Icons8 Background Remover's unwatermarked 2048×2048 free demos. |
| Suitable uses · historical assessment | Users who want true 4x (2048×2048) watermark-free faithful super-resolution without creating an account | Designers with an Icons8 prepaid pack ($0.20/image) or subscription needing up to 500-image batch upscaling + 1-click background removal |

| Pricing transparency | 32 / 35 Anonymous guests can select `400%` (4x) or `200%` (2x) directly on the home page, click 'Upload & Start', and download a 100% watermark-free 2048×2048 (4x) PNG without signing up or entering a card (Screenshots ②③). | 18 / 35 Landing page (01_landing.png) advertises 'Images can be upscaled up to 7680x7680px' without upfront notice that free trials are capped at 2x and watermarked. Uploading the 512×512 anchor grants 3 guest demo upscales ('2 demo upscales left'), but caps free output at 2x (1024×1024) with a server-side imgproxy watermark (02_workspace.png); clicking 'Enlarge to 4x' or 'Remove watermark' opens the '$0.20 per image / $9 per month' Upgrade modal (03_download.png). |
