The free card states 3 daily credits but other free statements conflict, so a single free allowance is unconfirmed. The 1/3-credit rules concern watermark removal, not a separately stated background-removal rate. Verification has gaps; unknown prices and quotas are not inferred.

| Measured fixture results | Tested scale: 4× | Tested scale: 2× |
| Fixture findings | The 4× upscale remains smooth and clean, achieving 26.89 dB PSNR and 0.8867 SSIM with legible main sign text, though fine high frequencies are smoother than generative diffusion models. | Denoising and text edges were retained; the tested free tier was limited to 2× at 1024px. |
| Original historical observation | Uploaded 512×512 anchor image; selected By Dimensions mode setting target to 2048×2048 (4.0x upscale). Client HTML5 Canvas rendered deliverable in 3.41 seconds, achieving 26.89 dB PSNR, 0.8867 SSIM, and 15.07 dB plate PSNR. Deliverable remained clean and smooth; direct Base64 PNG download. | DeWatermark Image Enhancer's 2X model prioritizes faithful denoising and edge sharpening, scoring PSNR = 27.12 dB overall and 30.46 dB on the engraved wooden sign without hallucinated textures, though 4X (2048×2048) is locked behind Pro. |
