How do I sharpen a blurry photo?

Upload it, apply the sharpen effect and compare the preview. Very blurry images may need the AI Unblur tool instead.

Sharpening cannot add detail that was never captured, so use it for slightly soft photos rather than ones that are clearly out of focus.

Can sharpening ruin a photo?

Too much sharpening adds halos and noise, so use a moderate value.

Why do white halos appear around edges when I sharpen too much?

Sharpening increases contrast right at the edges. Push it too far and the light side of an edge gets brighter and the dark side darker, creating visible glowing outlines and exaggerated noise. Reduce the amount until edges look crisp but natural, and zoom in on the preview to check before downloading.
