FAQ
What sharpen strength is right?
30-60 looks natural; above 80 you risk halos and amplified noise — increase gradually while previewing.
Can it fix completely blurry photos?
No. Sharpening only amplifies existing edge contrast; it cannot reconstruct missed focus and over-sharpening exaggerates noise.
Is my image uploaded?
No, everything runs locally in your browser.
