Frequently asked questions

Can I control the sharpening intensity?

Our tool applies a standard sharpening pass. For photos needing multiple passes, apply the tool several times by downloading and re-uploading.

Will sharpening fix a very blurry photo?

Sharpening enhances edges in photos that are slightly soft. Very blurry photos cannot be fully recovered by sharpening.

Does sharpening increase file size?

Slightly, since more edge detail means less efficient compression.

Can sharpening make photos look worse?

Over-sharpening can create visible halos around edges. Our tool applies a balanced sharpening amount suitable for most photos.

Is sharpening the same as increasing contrast?

No. Sharpening specifically enhances local edge contrast. Brightness and contrast adjustment changes the overall tonal range.
