The feature FAQ confirms watermark-free transparent PNG/blurred-background downloads with a free account; replacing with a new background allows one free download per day, while premium backgrounds require a subscription. The pricing table says Limited without quantifying daily transparent-PNG limits. General AI credits or the one-daily replacement limit are not applied to transparent cutouts.

| Measured fixture results | Tested scale: 4× | Tested scale: 4× |
| Fixture findings | The tested 4× photo configuration produced smooth output with text retained; other settings remain untested. | The preview showed useful deblocking and colour retention; guest download required login. |
| Original historical observation | Configured to Photo + 4x + Low Noise Reduction, Bigjpg exported a clean 2048×2048 PNG scoring PSNR = 28.27 dB and SSIM = 0.9790 with smooth tonal transitions and zero generative hallucinations. | MyEdit's 4x upscaler delivers excellent deblocking and color fidelity (PSNR 27.35 dB, SSIM 0.8882) without hallucinated artifacts, though guest previews carry a tiled watermark and require login to export. |
| Suitable uses · historical assessment | Users wanting a no-login, zero-watermark 4x (2048px) upscaler with 5-level adjustable noise reduction for photos and illustrations | Users seeking high-PSNR denoising and 4x upscaling who don't mind logging into a CyberLink account for 1 free daily export |
