Frequently Asked Questions
- How does AI image upscaling work?
- Real-ESRGAN uses a neural network trained on millions of image pairs to predict and generate fine details when increasing resolution. It produces much sharper results than traditional interpolation (bilinear, bicubic).
- What's the difference between 2x and 4x?
- 2x doubles the width and height (4x total pixels). 4x quadruples them (16x total pixels). 4x takes longer but produces a much larger, more detailed image.
- Can I upscale old or blurry photos?
- Yes. Real-ESRGAN is particularly good at enhancing old, compressed, or low-resolution photos. It adds natural-looking detail and sharpens edges without creating artifacts.
- Is there a size limit?
- The AI processes on GPU servers, so very large images (over 4K) may take longer. For best results, start with the highest quality source image you have.
