Frequently Asked Questions

What is AI image upscaling?

AI image upscaling uses deep learning algorithms (specifically Real-ESRGAN) to intelligently enlarge images while adding realistic details. Unlike traditional scaling which just stretches pixels, AI upscaling generates new details based on patterns learned from millions of images.

Is it safe to upscale images online?

Yes. All processing happens directly in your browser using TensorFlow.js. Your images are never uploaded to a server, ensuring complete privacy and security. The AI model runs entirely on your device.

What upscaling factors are available?

We support 2x and 4x upscaling. A 2x upscale doubles the image dimensions (e.g., 500px → 1000px), while 4x quadruples them (e.g., 500px → 2000px). Both add intelligent detail enhancement.

What images work best for upscaling?

AI upscaling works best on photos, illustrations, and digital art. It's particularly effective on images that need to be enlarged for print, high-resolution displays, or when you need more detail from a lower-resolution source.
