Image Sharpening Tool
Enhance blurry photos and bring out fine details. Apply a customizable unsharp mask to your images locally, making edges crisp and clear.
Enhance Image Clarity
Slightly out-of-focus photos or compressed web images can look soft and muddy. This tool applies a mathematical convolution matrix (often called an Unsharp Mask) to your image, increasing the contrast along the edges of objects. This instantly creates the illusion of a crisper, more detailed photograph without needing complex editing software.

Frequently Asked Questions
No, sharpening tools can only enhance existing edges. If a photo is severely out of focus or suffers from heavy motion blur, the data cannot be magically recovered.
Over-sharpening causes 'halos' (bright outlines around dark edges) and increases digital noise/grain, making the photo look unnatural.
