Open Picture to Realistic Drawing Converter and select Add File, or drag and drop the image.

Under Style on the right, choose Realistic, Classic or Detailed.
Realistic balances subtle outlines with detailed shading and retains the lights and shadows.
Detailed: the detailed style emphasizes shading, including in bright areas, so the image has almost no white areas. It suits landscape photos; portraits may need a more minimal look.
Classic uses simple shading and bold outlines for line drawings and subtle portraits.

The preset controls colour effects, pencil stroke thickness and contrast. Options include felt tip pen, colour drawing, pop art, low contrast art, high contrast, soft black and white preset and simple paintbrush. The main presets are Simple, Light and Pen.
Simple preset gives a paintbrush look. Pen preset creates sharp, bold borders with medium shading. Light preset creates line drawings and stencils with less shading and more black-and-white areas.
Use the preview box over the original photo to compare the settings.

Use Contour, Hatching and Colourization to adjust edge strength, shading, stroke thickness and intensity.
Contour controls the outline. Higher edge strength or intensity creates bolder, more detailed borders.
Hatching adds zigzag lines to darker areas. Keep the stroke thickness and strength low if heavy cross-hatching looks unnatural.
Colourization adds colour. Choose the colours and a uniform pencil or free-flowing paintbrush effect.
