Nano Banana 3 is an AI image generator and editor that turns text prompts and reference images into polished visuals for ads, mockups, posters, product scenes, and social content directly in the browser.
What is Nano Banana 3?
Nano Banana 3 is an AI image workspace for text-to-image generation, image-to-image editing, and reference-guided design. It accepts text prompts (up to 4000 characters) and optional reference images (up to 4 files, 15MB each) and outputs high-quality images suitable for campaigns, mockups, and publishing. The tool runs entirely in the browser and is built by the Nano Banana team.
Key Features
- Text-to-Image Generation — Turn short ideas or detailed briefs into visuals with control over subject, style, lighting, and composition.
- Image-to-Image Editing — Upload an existing image and request targeted changes like background replacement, scene restyling, or atmosphere adjustments while preserving key details.
- Multi-Reference Composition — Combine up to 4 reference images (people, products, materials, poses) into a single coherent output with consistent visual direction.
- Readable Text Rendering — Generate images containing readable headlines, labels, packaging copy, signs, or diagrams by specifying exact wording, type style, and placement.
- Prompt Optimization — Refine rough notes into production-ready prompts with composition, camera angle, lighting, typography, and quality constraints before spending credits on generation.
- World-Aware Prompts — Create infographics, product explainers, or geographically grounded scenes with factual context beyond decorative style.
- Multi-Aspect Ratio & Model Selection — Choose aspect ratio (including matching input image) and switch between models if results are not effective.
Who is it for?
- Brand designers — quickly generate poster concepts with readable text and multiple layout options before moving into final design.
- Ecommerce marketers — test product scenes, backgrounds, and ad crops without rebuilding mockups from scratch.
- Content creators — turn one idea into vertical, square, and wide versions for different social channels, then refine the best one.
- Education creators — describe structure, labels, and teaching goals in a single prompt to produce visual explainers and diagrams.
- Agency strategists — produce more directions to compare, clarify prompts with clients, and make faster edits after feedback.
