Turn a loose character sketch into a game scene.
The white bird, teal flower, and orange branch remain recognizable while the finished image builds them into a dark fantasy encounter.
GPT Image 2.5 Sketch to Image
Sketch the layout. Add the details. Turn your idea into an image with brushes, shapes, and a few words.
Loading your drawing canvas…
See what a simple sketch can become.
Start with positions, silhouettes, and a few visual cues. These examples show how a drawing can guide subject placement while the prompt defines the final medium, detail, and atmosphere.
Watch the supplied sketch-to-image example.
Use an object outline to direct the rendering style.
The camcorder drawing establishes the silhouette and viewpoint; the result interprets it as a luminous green wireframe model.
Carry a small character drawing into a painted portrait.
The head covering, face placement, and hanging ornament guide a textured oil-paint interpretation of the cat.
Block out a subject and scene before adding realism.
The red car, standing figure, and sun define the composition before the result adds a coastal road, sunset light, and photographic detail.
Follow a landscape outline into a realistic scene.
Follow the mountain ridges and winding river from the drawing into the rendered scene. The reference supplies the arrangement; the finished image adds depth, texture, and light.
From a few lines to a clear direction.
A drawing can express a layout that is hard to describe. Use GPT Image 2.5 sketch to image to give your prompt a visual starting point.
1. Draw the composition
Place the subject, background, and supporting objects. Use simple shapes for proportions, a brush for contours, and short labels for important details.
2. Describe the finish
Add the material, mood, lighting, and medium you want. Your current canvas is saved automatically when you generate. Draw something first: empty canvases cannot be submitted.
3. Generate and refine
Check the credit cost, sign in, and generate. Review the image against your layout. Adjust the drawing or prompt, then apply your updated reference for the next attempt.
Draw what words leave open.
Room layouts
Block out a sofa, table, windows, and walking space. Name the materials and lighting in your prompt. Use the sketch to communicate furniture placement before exploring a finished room.
Product concepts
Draw a silhouette, mark the handle or opening, and show a few color areas. Ask for a particular material and viewpoint to explore how the concept could look.
Poster compositions
Reserve space for a headline, central image, and footer. Label those areas, then specify whether labels should appear in the final design or only act as instructions.
Keep the sketch simple. Make the intent specific.
Separate shapes clearly
Give important objects enough space and use contrasting colors to distinguish them. Avoid filling the canvas with small marks that compete with the main composition.
Say what must stay
Ask to preserve the subject’s position, silhouette, or relative scale. Then describe the changes you want: a new medium, realistic textures, or a different atmosphere.
Check before you submit
Export includes the visible canvas background. Choose a background that contrasts with your strokes, apply the latest reference, and check the preview before generating.
Sketch to image questions.
What is GPT Image 2.5 sketch to image?
It is a workflow that uses a drawing as a visual reference for image generation. Draw the main shapes and their positions, then add a text prompt describing the finished image. This independent website combines a browser drawing board with its GPT Image 2.5 generator.
Do I need to know how to draw?
No. Start with simple outlines, arrows, and a few labels. Show where important objects belong and leave fine details such as material, lighting, and texture to your prompt. A clear layout is more useful than a polished drawing.
What does the confirm button do?
The checkmark exports your canvas as a PNG reference and adds it to the generator. Choose Landscape (1536 × 1024), Square (1024 × 1024), or Portrait (1024 × 1536) with the Canvas control. Your selected background, including transparency, is preserved. Toolbars and selection boxes are excluded. Confirming a sketch does not start a generation task or use credits.
Where are my sketches saved?
The current editable draft and applied PNG reference are saved locally in this browser when storage is available. They are not automatically synced to another device. Clearing browser data may remove them. Download a PNG to keep a separate copy; a PNG does not preserve editable objects.
When is my sketch uploaded?
Drawing and exporting happen in your browser. The applied reference is uploaded through this website’s image upload service when you submit a generation task. AI generation requires signing in and uses account credits; the cost appears before submission.
Will the generated image match every line?
The sketch guides composition, but generation may reinterpret proportions, labels, and small details. State which positions and shapes to preserve, inspect the result, and revise your sketch or prompt when needed.
Can I edit a sketch after using it as a reference?
Yes. Continue drawing or undo a change, then confirm your sketch again. This replaces the generator’s sketch reference with a fresh PNG. An already submitted generation task continues using the image originally submitted.
