Question 1

Will sharpening improve a blurry or out-of-focus photo?

Accepted Answer

Sharpening enhances edges and details in images that are slightly soft. It cannot recover detail from severely out-of-focus or motion-blurred photos, but can make good photos look noticeably crisper.

Question 2

Can I preview the sharpening before downloading?

Accepted Answer

Yes. A real-time preview updates as you move the strength slider, so you can find the ideal sharpening level before downloading.

Question 3

How does the sharpening algorithm work?

Accepted Answer

We use an unsharp mask convolution matrix — the same technique used by professional editing software. It calculates local contrast differences at edges and amplifies them to create the perception of greater sharpness.

Question 4

Can I apply blur instead of sharpening?

Accepted Answer

Yes. Set the slider to a negative value to apply a gaussian blur effect instead of sharpening — useful for privacy blurring or creating dreamy soft-focus effects.
