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. UpscalePro supports up to 4x upscaling.

Is UpscalePro free to use?

Yes. UpscalePro includes 3 free credits per month with signup, and you can upgrade to Pro or buy extra credits for more upscales and restorations.

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 at 2x or 4x scale.

What's the maximum output resolution?

UpscalePro supports 2x and 4x upscaling. A 4x upscale can take a 1000x1000 image to 4000x4000, which is ideal for sharper downloads, print use, and higher-resolution displays.

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

2x doubles your image dimensions (e.g., 1000x1000 → 2000x2000). 4x quadruples them (1000x1000 → 4000x4000) for the highest resolution available in UpscalePro.

Is UpscalePro better than Topaz Gigapixel?

UpscalePro offers comparable browser-based convenience with Real-ESRGAN-powered upscaling and built-in photo restoration, without requiring a desktop install.
