The fastest way to a sketch effect that looks hand-drawn is a prompt in AI Playground. Upload a photo, pick an image model and describe the look. Your photo comes back as a pencil sketch, an ink drawing, clean line art or an outline over the original.

Because the drawing starts from a description, you call the shots: the medium, the paper, the line weight and what stays exactly as it was. Below: what a sketch is good for, the five-step method, and a ready prompt for each look.

What you can make with a sketch effect

Redraw one photo and it can travel almost anywhere:

  • Stickers. Line art on a transparent background becomes a hand-drawn sticker for any design.
  • Presentations and portfolios. A sketched portrait or product shot gives slides and case studies a crafted, handmade feel.
  • Profile pictures. A pencil portrait stops the scroll in a feed full of filtered selfies.
  • Gifts and prints. Sketch a pet or a couple in pencil and you have a card or a framed print.

How to turn a photo into a sketch with AI

The prompt route redraws the photo instead of laying a texture over it. So the result reads as a real drawing, with strokes that follow the shapes of the face and the scene. Five steps get you there.

Step 1. Open AI Playground

Open AI Playground and choose Image in the bottom-left switcher. Image mode makes your photo the starting point: the model works from it instead of generating an image from nothing.

Step 2. Upload your photo

Add the photo with the Image button at the top of the prompt box. Pick one with a clear subject, visible edges and good contrast. Those become the lines of your drawing.

Portraits, pets and landscapes all work. Side light is your friend: a face lit from one side gives the shading more to play with than a flat, front-lit selfie.

Step 3. Pick the model for the look

Open the model menu and pick one of these:

  • Nano Banana 2.1 for pencil sketches and sketches on a new background. It restyles the whole image and keeps the person recognizable.
  • GPT Image 2.5 for ink sketches and line art. Its Sunburst variant handles fine hatching, and it exports PNG with a transparent background.
  • Ideogram 4.5 Precise Edit for outlines. It changes only what you name, so the photo underneath stays pixel-intact.

Step 4. Describe the sketch, then lock the face

Start with the change: the medium, the paper, the line weight and how much shading you want. "Graphite pencil on off-white paper with light cross-hatching" gives the model far more to go on than "make it a sketch".

Then list everything that must not move: the face, expression, pose, hairstyle and composition. That lock list keeps the drawing looking like the person in your photo, not a stranger drawn in the same pose.

Step 5. Generate and refine

Generate, then check the result twice: zoomed in on the face, and at the size you will actually use it. Small features like eyes and lips are where a sketch most often drifts.

Fix it with a follow-up message instead of starting over. Ask for lighter shading, thicker lines or less background, one change at a time, and you see what each one did.

Sketch effect prompt examples

Each example below is ready to paste into Step 4. Swap in your photo's details and keep the lock list.

Pencil sketch

Reach for Nano Banana 2.1. A pencil portrait lives or dies on likeness, and this model keeps the person recognizable while it restyles everything else. It also refines in conversation, so lighter shading is one follow-up message away.

Pencil sketch from a photo

Turn this photo into a realistic graphite pencil sketch on off-white paper, with soft shading, visible pencil strokes and light cross-hatching in the shadows. Keep the face, expression, pose, hairstyle and composition exactly as in the photo. No color, no added objects, no text.

Want a rougher, unfinished study? Ask for loose construction lines and leave the edges of the paper blank.

Ink sketch

Go with GPT Image 2.5 Sunburst, which renders sharp detail and rich texture. Ink is less forgiving than pencil: every line is dark and final, so the precision variant is the safer pick.

Ink sketch from a photo

Redraw this photo as a black ink pen sketch on white paper, with confident fine lines, dense cross-hatching for shadows and clean white highlights. Keep the person’s face, proportions, pose and the framing of the photo exactly the same. No gray wash, no color, no text.

Craving a vintage feel? Add warm paper texture and light film grain to the same prompt.

Turn a photo into line art

Use GPT Image 2.5. Line art strips the photo down to its contours, and the transparent PNG is ready to drop onto any design, sticker or print.

Line art from a photo

Convert this photo into clean black line art with a single even line weight, tracing only the main contours and key facial features, on a transparent background. Keep the subject’s face, pose, proportions and composition exactly as in the photo. No shading, no fill, no background details.

Making a coloring page? Ask for slightly thicker lines and closed shapes.

Outline a picture

Use Ideogram 4.5 Precise Edit. Unlike line art, an outline sits on top of the photo. This model changes only the area you name, so the picture underneath stays exactly as you shot it.

Outline effect on a photo

Add a bold white hand-drawn outline that traces the edges of the person, slightly offset from the body like a sketch stroke. Keep the photo itself, the person’s face, pose, colors, background and composition completely unchanged.

The same prompt stretches to playful looks too: a double outline, a mirrored outline on the opposite side of the subject, or an outline built from small shapes. Neon pink or yellow lines on a dark photo push the effect into '90s graphic design.

Sketch on a new background

Send your subject somewhere new, even outer space, and sketch them in one step with Nano Banana 2.1. The model changes the setting while keeping the subject recognizable.

Sketch on a new background

Turn the person in this photo into a pencil sketch and place them on a deep blue starry space background with soft glowing planets. Keep the person’s face, pose and proportions exactly as in the photo, and keep the sketch lines black and white.

Prefer a plain backdrop? The Background Changer swaps in a ready-made background or one you upload.

Most weak sketches start with the photo or the prompt, not the model.

Tips for a cleaner drawing effect

One medium per prompt

Pencil plus ink plus watercolor in one go muddies the strokes. Pick one, then try the next as a follow-up.

Name the paper

Off-white, warm or plain white paper changes how finished the drawing feels.

Change one thing per follow-up

Shading, then line weight, then background, so you can tell what each change did.

Simplify busy backgrounds

A cluttered scene turns into a tangle of lines, so ask the prompt to drop it or keep only the main subject.
