Image Sharpen Tool
Apply an adjustable convolution sharpen kernel to local pixels.
How Image Sharpen Tool works
Image Sharpen Tool is designed to apply an adjustable convolution sharpen kernel to local pixels. A five-center-minus-four-neighbors kernel creates a sharpened value, which is blended back toward the source by the selected amount. Image Sharpen Tool adds a focused result for this operation. For Image Sharpen Tool, the labeled output in this page makes the transformation auditable from the current controls instead of relying on visual guesswork.
The default sharpen kernel weights the center by five and subtracts its four direct neighbors. Use it to restore local contrast after resizing or to clarify slightly soft screenshots before publishing. In Image Sharpen Tool, after confirming the default, try a nearby value and use the new output to trace the selected parameter.
Limits, output, and privacy
Strong sharpening creates halos around high-contrast edges and amplifies compression artifacts or sensor noise. For Image Sharpen Tool, large source images require more memory because the browser holds both source and output pixel buffers while processing. Image Sharpen Tool keeps the operation client-side. With Image Sharpen Tool, input remains private to the current browser session, with no network request needed to calculate, preview, copy, or export.
