Have you ever thought about turning your normal photo into a hand-drawn sketch? Earlier, you had to visit an artist to get a portrait made, but now technology has made it super easy.
Google’s Gemini AI is a powerful tool that can turn any photo into a digital sketch in just a few seconds.
In this guide, we’ll explain how Gemini works, what steps you need to follow, and which prompt gives the best results.
What Is a Sketch Photo?
A sketch is a simple art form that uses lines and shades instead of colors. It focuses more on expressions and details than on decoration.
A good sketch doesn’t just copy a photo-it shows the mood and personality of the person, like a smile, confidence, or attitude.
With the help of AI, anyone can now create sketch-style portraits. Using Gemini AI, you only need a photo and a short instruction (prompt) to turn it into a beautiful digital sketch.

What Does Gemini AI Do?
Gemini is Google’s advanced AI platform that understands both text and images. You can chat with it, write content, or even create art.
It has a special image model known as Nano Banana, which is designed for creative artwork, sketch effects, and image editing.
This model studies your photo-its texture, light, and small details-and then recreates it as a clean and balanced digital sketch. The results often look like they were drawn by a real artist.
How to Convert Your Photo to Sketch with Gemini
First, open gemini.google.com in your browser. If you already have a Google account, sign in with it. Once you’re logged in, you’ll see a “Start chat” option. Click on it to open a new chat window where you can upload your photo.
Best Prompt Example for Gemini AI
“Create a clean black and white sketch portrait of the person in this photo in a minimalist art style. Focus on the head and shoulders. Use bold contour lines and soft shading. Make it look artistic yet realistic, with a calm and confident expression. Keep the background plain white or light gray.”
This prompt works well because it gives clear and detailed instructions, helping Gemini understand exactly what kind of image you want.
