Unblur Image — FAQs
The tool uses an unsharp masking algorithm — a technique originally from darkroom photography. It enhances edge contrast to make images appear sharper and more defined.
Start with Strength 4 and 2 passes. For heavily blurred images, try Strength 6–8 with 3–4 passes. Too high a setting can create artifacts.
This tool works best on slightly blurry or soft-focus images. Severe motion blur or heavy defocus cannot be fully reversed as the original detail is missing.
Images up to about 20 MB are supported. Very large images may take a moment to process, especially with multiple passes.
