Frequently Asked Questions
AI upscaling uses neural networks (Super-Resolution) trained on millions of images to predict and add realistic detail when enlarging. Results are sharper than traditional bicubic scaling.
It can improve clarity and add detail, but cannot fully recover a severely blurry or out-of-focus photo. Start with the sharpest original you have.
2x gives excellent results on most images. 4x is best for simple subjects like portraits — very detailed textures can show some softening at 4x.
Yes — a 2x upscale quadruples the pixel count, increasing file size significantly. Use our Image Compressor afterwards if you need a smaller file.
