About this tool
This tool uses a simplified tone model: darker original tones stay darker, while the strength setting controls how much of the original tone is kept in the sketch version. The browser preview applies that tone change to a gradient, so you can judge the strength. It is a tone effect, not a full edge-detection sketch pipeline, so fine pencil lines from a real photo are not reproduced here.
Frequently asked questions
Is this a real pencil sketch?
It is a simplified tone effect for previewing strength, not a full sketch pipeline with edge detection and shading.
What does higher strength do?
It keeps more of the original tone in the result, so the sketch looks darker and more defined.
