How to Sharpen Blurry Photos

Sharpening enhances edge contrast to make images appear more detailed and in focus. Our tool uses unsharp mask technology for natural-looking results.

Start with 30% intensity and adjust up. Over-sharpening creates unnatural halos around edges. Sharpening is best for slightly soft images, not severely out-of-focus photos.
