Frequently asked questions
How is the effect produced?
The image is converted to grayscale, a copy is inverted then blurred, and the two are blended with “color dodge”. It is the classic pencil-sketch technique, done here pixel by pixel.
Is my image uploaded?
No. All processing happens in your browser via the canvas. Your photo never leaves your device.
What does the intensity slider do?
It sets the blur radius: higher values make outlines stronger and the look more “drawn”. A low value keeps more detail.
Which photos give the best result?
Well-contrasted, sharp images (portraits, buildings, objects). Very dark or blurry photos give a less readable sketch.
