Is UpscalePro really free?

Yes. UpscalePro includes 3 free credits per month with signup. There are no watermarks or hidden fees.

Do I need to sign up?

No signup is required. Upload an image and start upscaling immediately. Creating a free account is optional and gives you extra daily upscales.

Are there watermarks on free images?

No watermarks, ever. Free and Pro images are identical in quality — your upscaled images are clean and ready to use for any purpose.

What's the maximum free upscale resolution?

UpscalePro supports up to 4x upscaling on the free tier.

How does UpscalePro compare to paid upscalers?

UpscalePro uses Real-ESRGAN, the same state-of-the-art AI model used by many paid tools. The quality is comparable to Topaz Gigapixel AI ($99), but UpscalePro is free and runs in your browser.

Your images are stored securely in your account history so you can re-download them. We never share your images or use them for AI training. You can delete your history at any time.
