Unblur & Sharpen an Image Online
Sharpen blurry photos with an adjustable unsharp filter.
This sharpens blurry photos using an unsharp-mask technique that enhances edge contrast — genuinely effective on mild blur or slightly soft focus, though it can't recover detail that was never captured.
What sharpening actually does (and its limits)
Sharpening works by increasing contrast along edges, making them appear more defined to the eye — it's an enhancement technique, not a true restoration process, so it can't invent detail that motion blur or an out-of-focus shot never captured in the first place. It works best on photos that are only mildly soft.
Frequently asked questions
Can this fix a severely blurry or out-of-focus photo?
Not fully — heavy blur represents genuinely lost detail that sharpening can't recreate. This tool works best on mild blur or slightly soft images, giving a meaningful but not miraculous improvement.
Why does over-sharpening look worse instead of better?
Pushing the strength too high exaggerates edge contrast to the point of creating visible halos and noise — moderate settings usually look more natural than maximum strength.
