Frequently Asked Questions

How does image sharpening work?

Sharpening applies a convolution kernel that boosts contrast along edges. The result makes details look crisper and reduces the soft look caused by camera shake or compression.

Can I sharpen multiple images at once?

Yes. Drop a whole batch and the same sharpening strength is applied to every image in one run.

Will sharpening make a very blurry photo sharp?

Sharpening enhances existing edge detail — it cannot recover detail that was never captured. It works best on slightly soft images, not heavily out-of-focus ones.
