Edge Parameters
Toggle between White edges on Black (Neon) or Black edges on White (Sketch).
The Sobel operator calculates the gradient intensity of each pixel. Use lower values for photographic texture and higher values for bold structural layouts.
Professional Edge Detection for Everyone
Our Edge Detection tool uses mathematical convolution filters (like the Sobel and Canny operators) to identify the structural outlines of your images. It maps out the intensity of brightness changes, creating a 'map' of all the lines and edges in the photo. This can be used for artistic 'neon' effects, technical shape analysis, or as a base for vector tracing.

Frequently Asked Questions
Common questions about our Edge Detection tool.
How does it work?
Our engine looks at every pixel and compares it to its neighbors. High differences in color/brightness are marked as edges.
Can I use this for coloring book pages?
Yes! High-sensitivity edge detection in monochrome mode can turn any photo into a coloring-style outline.
