What is an AI image upscaler?

An AI image upscaler uses artificial intelligence to enlarge images while adding detail that wasn't in the original. Unlike traditional resizing that just stretches pixels, our Real-ESRGAN AI analyzes the image and intelligently reconstructs missing information, resulting in sharper, more detailed enlarged images.

How does AI upscaling work?

Our upscaler uses Real-ESRGAN (Real-Enhanced Super-Resolution Generative Adversarial Network), an AI trained on millions of images. It learns patterns and textures, then applies this knowledge to add realistic detail when enlarging your images. For faces, we use GFPGAN to specifically enhance facial features.

What's the maximum input file size?

You can upload images up to 10MB in size. For best results with 4x upscaling, we recommend starting with images at least 512x512 pixels. Very large images may be automatically resized before processing to ensure optimal results.

What image formats are supported?

We support JPG, JPEG, PNG, and WebP formats for both upload and download. PNG is recommended for download when you need the highest quality, while JPG provides smaller file sizes.

When should I use face enhancement?

Enable face enhancement when your image contains people, especially portraits or group photos. GFPGAN technology specifically targets facial features—sharpening eyes, improving skin texture, and enhancing expressions while keeping results natural.

Will upscaling reduce image quality?

No! Unlike traditional resizing, AI upscaling actually adds detail. Our Real-ESRGAN model reconstructs textures, edges, and fine details that weren't visible at smaller sizes. The result is often sharper and more detailed than the original.

Should I choose 2x or 4x upscaling?

2x doubles your resolution and takes ~12 seconds—great for social media and web use. 4x quadruples your resolution and takes ~25 seconds—ideal for printing and large displays. Choose based on your final use case and desired output size.

How many credits does upscaling cost?

2x upscaling costs 2 credits per image. 4x upscaling costs 3 credits per image. Face enhancement is included at no extra cost. New users get 5 free credits to start.

What download formats are available?

You can download your upscaled images as PNG (highest quality, larger file) or JPG (good quality, smaller file). PNG is recommended for further editing or printing, while JPG is better for sharing online.

Can I use upscaled images commercially?

Yes! Images you upscale are yours to use however you want, including commercial projects. We don't claim any rights to your processed images. Just ensure you have rights to the original image.
