Bring detail back to a soft or slightly blurred photo. Edges and texture are strengthened where they should be sharp, while skin and smooth areas stay clean instead of turning gritty.
How the ai image sharpener works
Upload the soft photo and say where the sharpness matters, for example 'sharpen the eyes and hair, keep the skin smooth' or 'this is soft from camera shake, recover the text on the sign'. Run the tool and inspect edges at full size for halos. If the result looks crunchy or noisy, ask for a lighter touch and run again on the same upload.
Tips for the best results
Say what caused the softness, since focus miss, shake and compression each need different handling. Name the areas that must be sharp and the ones to leave smooth. Light sharpening applied twice usually beats one heavy pass. Very blurred sources have little to recover, so start from the best copy you have.
