How image sharpening works
Upload an image and apply the sharpening control available in the editor. Compare the preview with the original at full size. Sharpening increases local contrast around edges, which can make details appear more defined, but it cannot reliably restore information that was never captured.
Avoid over-sharpening
Strong sharpening can create halos, emphasize noise, and make skin or smooth surfaces look harsh. Start with a subtle adjustment and inspect both fine details and larger areas. A result that looks crisp when zoomed in may appear unnatural at normal viewing size.
Use the right source image
A well-focused, correctly exposed original usually produces the best result. If a photo is motion-blurred or very low resolution, sharpening may have limited benefit. Keep the original and compare exports before choosing the final version.
