Frequently asked questions
How does the sketch effect work?
We compute Sobel edge gradients on the grayscaled image, then blend or threshold the edges depending on style: 'pencil' overlays soft lines on greyscale, 'line' pure-black on white, 'ink' boosts edge contrast.
Is the photo sent anywhere?
No. The whole pipeline (grayscale, Sobel, blending) runs on a canvas in your browser — your image stays on the device.
Why is my sketch noisy?
Edge detection is sensitive to JPEG compression artifacts and high-ISO grain. Lower the strength slider, or pre-process with a slight blur in another tool first.
