This tool uses browser-native resampling (the same smoothing the canvas applies when scaling). It enlarges pixels by interpolation, which softens detail rather than inventing new ones — it is not AI super-resolution and won't recover detail that isn't there. For crisp pixel art, pick Nearest-neighbor to avoid blur; for photos, Bicubic gives the smoothest result.
