What is an AI image upscaler?

An AI image upscaler uses artificial intelligence to increase the resolution of images while adding realistic detail. Unlike traditional upscaling which creates blurry results, AI upscaling produces sharp, detailed images at higher resolutions.

Is UpscalePro free to use?

Yes! UpscalePro offers 3 free upscales per day (5 with a free account) for images up to 5MB. Upgrade to Pro for unlimited upscales and 20MB file limit.

What image formats are supported?

UpscalePro supports JPEG, PNG, and WebP images. Upload any of these formats and get a high-resolution result instantly.

How does the AI upscaling work?

UpscalePro uses Real-ESRGAN, a state-of-the-art AI model trained on millions of images. It predicts and generates realistic detail when increasing resolution, producing sharp, natural-looking results.

What's the difference between 2x and 4x?

2x doubles your image dimensions (e.g., 1000x1000 → 2000x2000). 4x quadruples them (1000x1000 → 4000x4000). Use 4x for maximum quality or when you need images for printing.

Is my image stored or shared?

No. We do not store the images you upload after processing is complete. Your image is sent to our AI for upscaling and immediately discarded.
