How to turn a photo into a drawing or illustration with AI

To turn a photo into a drawing or an illustration with AI, upload it as a reference image, describe the visual treatment you want and specify what must stay recognizable. Review the result beside the original before exporting.

Open Deepnia Image, upload your photo and choose Nano Banana Pro, built for subject consistency.

Working from the photo itself is different from asking a generator to imagine a similar scene from text: the photo keeps your composition.

Decide what “illustration” means for your project

An illustration can be a loose watercolor, a flat editorial drawing, a pencil sketch or a textured collage. Those treatments simplify a photograph in different ways. A watercolor may soften boundaries, while a geometric treatment can replace curves and texture with a smaller number of clear shapes.

Choose based on the destination. A small profile picture benefits from a recognizable silhouette and uncluttered background. A blog cover can support a more expressive treatment, but still needs a clear subject. A diagram explaining an object may need more structural accuracy than a decorative greeting card.

Before generating, write two lists: “must stay” and “may change.” For a cup on a café table, the cup’s position and empty headline space might belong in the first list. Surface texture, edge softness and background detail can belong in the second. This makes your request specific enough to review.

Prepare a source image that is easy to interpret

Start with a clear, well-lit image in which the important subject is visible. A heavily blurred or obstructed subject leaves more room for invention. If you need the entire object, avoid a source that cuts it off. An editing tool cannot reliably recover factual details that were never recorded.

Remove irrelevant sensitive information before uploading. A desk photograph may contain an address, private document or recognizable screen. Work from a copy and keep the original unchanged. If you use someone else’s image or a recognizable person, make sure the proposed use and modification are appropriate before starting.

For practice, choose a simple still life instead of a personal photograph. A cup, plant or unbranded notebook gives you enough structure to judge whether the transformation worked. It also makes the exercise easier to share without exposing someone’s identity or private surroundings.

Separate the subject reference from a style reference

The source photo answers “what is in the image?” A style reference answers “how should it look?” These are different jobs. If you supply more than one image, make their roles explicit so the request does not accidentally blend their subjects.

For example, a café photograph might provide the arrangement, while an authorized watercolor sample suggests texture and color handling. Upload both images to Deepnia Image and say in the prompt which one is the subject and which one sets the style.

Write a transformation prompt with clear priorities

Use a short structure: transform the medium, preserve the important content, then define the allowed simplification. Example prompt for a source image of a cup on a table:

Transform the supplied café image into a watercolor-style editorial illustration. Preserve the cup’s position, the visible handle, the table angle and the empty space on the right. Use warm, translucent color washes and a subtle paper texture. Simplify small background details without adding new objects. Keep the cup recognizable and do not add lettering.

The preservation instructions identify what to inspect afterward. If the handle becomes distorted or the cup changes size, the output still needs correction even if the watercolor treatment looks appealing.

Run the transformation in Deepnia Image

Open Deepnia Image, upload your photo and choose Nano Banana Pro to keep the subject recognizable, or GPT Image 2 for a flat, graphic style. Prepare your “must stay” list before launching the transformation so you have a concrete basis for judging the result.

Compare two styles without changing the whole brief

If you are unsure which treatment suits the article, keep the same source and preservation list while changing only the visual treatment. This helps you compare styles rather than comparing unrelated scenes. You can plan both variants without generating them at the same time.

Example prompt for a geometric alternative:

Reinterpret the supplied café scene as a flat geometric illustration. Retain the cup’s location, overall silhouette and the table perspective. Use broad shapes with a limited cream, brown and muted-green palette. Leave the right side clear for a headline added later. Simplify texture, but keep the cup distinct from the background. No lettering or additional objects.

Judge each variant at the size where it will appear. The watercolor may feel warmer, while the flat version may read more clearly as a small thumbnail. Neither is automatically better: the relevant question is which one supports the message with fewer distracting details.

Inspect what changed, not only what improved

Place the original and the output side by side. Compare the subject’s outline, position, relative size and distinctive features. Then examine the relationships between objects: does the cup still sit on the table, and does the handle attach convincingly?

For a portrait, check recognizable facial proportions rather than accepting any attractive face as a successful transformation. For a real product, inspect shape, closures and markings. A stylized output can still misrepresent the subject, even when it is obviously an illustration.

Finally, check whether the output introduced something you did not request: new jewelry, extra props, invented labels or an altered background. Small additions can change the meaning of an image. Remove them instead of assuming they are harmless decoration.

Revise one unwanted change at a time

Suppose the treatment works but the output fills your planned headline space. Ask for that area to be simplified while preserving the accepted subject and style. If the cup’s outline is wrong instead, prioritize its shape. Correcting several issues at once makes it harder to evaluate the next result.

For a focused fix, ask Nano Banana Pro for a local edit on the output, keeping the accepted style. Keep both files and record which input produced each version; this prevents confusion when you compare attempts.

Prepare the final file and its description

Inspect the exported image rather than only the preview. Check its crop and dimensions in the final layout, and verify that the planned headline remains readable. If you need a different crop for another placement, review that version separately instead of assuming the composition will survive unchanged.

For a matching series across several placements, Seedream v5.0 Lite Sequential generates up to 15 consistent images at once. To add the headline itself, see how to generate readable text in AI images.

Use a descriptive filename such as “coffee-cup-watercolor-illustration.” Write alternative text around the useful visible content, for example: “Watercolor-style illustration of a coffee cup on the left of a wooden table.” Do not turn the description into a list of search keywords or claim the file is a camera photograph.

Frequently asked questions

Which AI can turn a photo into a drawing?

In Deepnia Image, Nano Banana Pro keeps the subject recognizable, while GPT Image 2 excels at graphic, flat styles.

Will an illustrated portrait preserve someone’s identity exactly?

Use Nano Banana Pro, built for subject consistency, and list the features to keep. Compare the result with the source and obtain the relevant person’s approval when appropriate.

Continue from a clear reference

Prepare one suitable source, one treatment and a short preservation list, then open Deepnia Image, choose Nano Banana Pro and paste one of the prompts above. If your instructions feel vague, use the image-prompt worksheet. If the first result changes too much, move to targeted image correction before replacing the entire concept.
