Use a photo editing app or software with a sketch or pencil effect
Open the photo in the app
Select the sketch, pencil, or drawing filter
Adjust contrast, brightness, and edge intensity if needed
Save or export the edited image
Use online sketch converter tools if you do not want to install software
Use mobile apps that offer photo-to-sketch effects
Use desktop software like Photoshop, GIMP, or similar programs
Convert the photo to black and white before applying the sketch effect for a stronger pencil look
Trace the photo manually on paper or a drawing tablet if you want a hand-drawn sketch
Scan or photograph the hand-drawn sketch after finishing
