Sharpen Image — Complete Guide

1What is Sharpen Image?

Bring back detail to soft photos with adjustable sharpening.

Sharpen Image is part of the Pixly suite of professional image tools. It runs entirely in your browser with no software to install, requires no design experience, and delivers results in seconds — whether you are processing one image or an entire batch. Every operation is applied on the full-quality decoded image, so the output preserves the fidelity of your original file.

2How does Sharpen Image work?

Sharpening applies unsharp masking: the engine creates a blurred copy of the image, compares it with the original, and amplifies the difference (the high-frequency detail) by the amount you set. Edges and texture get enhanced while flat areas stay untouched. The radius is chosen automatically from the image size so results look consistent between a 400 px thumbnail and a 4000 px photo.

An artifact guard limits over-amplification near hard edges to prevent the halos (bright outlines) that aggressive sharpening tools leave behind.
