Increase the resolution of an image while preserving sharpness and detail. The tool intelligently fills in new pixels so the result looks natural, not blocky.
Perfect for enlarging old photos, preparing low-res images for print, or making small thumbnails usable at larger sizes. Processing happens in your browser using client-side algorithms.
2x to 4x the original dimensions. A 500x500 image becomes 1000x1000 at 2x or 2000x2000 at 4x.
Sharpening is applied during upscaling to reduce blur. Results are better than simple stretching, but don't expect miracles from very small images.
It uses browser-based interpolation with sharpening. Not as advanced as GPU-based AI upscalers, but works instantly without uploads.
