Upscale an image

Enlarge an image to 2× or 4× its size with high-quality Lanczos resampling — useful for print sizing or upscaling small graphics.

Will upscaling add detail to my photo?

No tool can invent detail that wasn't captured; this uses high-quality resampling, which keeps edges smooth without artifacts. For photos, 2× usually looks noticeably better than 4×.

Is there a size limit?

The enlarged image may not exceed 40 megapixels. If your image is already large, pick 2× rather than 4×.
