What is Sharpen Image?

Sharpen Image boosts local edge contrast so photos look clearer. It helps after mild softness or light compression; it cannot invent detail that is already gone.

Questions

Why is the difference subtle on some photos?

Already-sharp images change less. Soft or compressed photos show a clearer before/after. Use Compare and raise Extra if needed.

Why do strong settings look crunchy?

High strength exaggerates edges and can create rings. Dial back to Soft or Medium for natural photos.

Does it change image size?

No. Output keeps the original pixel dimensions.

Is there a daily limit?

The free plan allows 5 downloads per day, with files up to 10 MB. Preview is unlimited.
