Nano Banana prompt generator
A free tool that turns a few choices into a structured Nano Banana prompt. Pick what you are making, describe the subject, and choose the setting, framing, light and style. Copy the result or open it straight in the image studio. No account needed.
How the prompt is built
Nano Banana models read prompts as plain language. The generator writes one or two sentences in the order that works best, the same structure described in the guide to writing Nano Banana prompts.
| Part | What it describes | Example |
|---|---|---|
| Subject | Who or what, with the details that matter | a ceramic mug with a matte sage glaze |
| Setting | Where the subject is | on a worn oak café table |
| Composition | Framing, angle and space | close-up at eye level, space on the left for text |
| Light | Source, direction and time of day | soft morning window light from the right |
| Style | Medium and finish | natural lifestyle product photography |
When you edit your own photo, the prompt starts with what must not change. Text that should appear in the image is quoted exactly, which is how Nano Banana 2.1 and Pro render readable lettering.
FAQ
Is the Nano Banana prompt generator free?
Yes. The generator is free, needs no account, and runs in your browser. Generating the image in the NanoBananas studio uses credits, and new accounts get 10 free credits with no credit card.
What makes a good Nano Banana prompt?
One or two plain sentences in this order: subject, setting, composition, light and style. Put any text that must appear in the image in quotation marks. When editing a photo, say what to keep before what to change.
Does it work for editing my own photo?
Yes. Tick the reference-photo option and choose what must stay the same, such as the face or the product label. The prompt then opens in Image-to-Image mode, where you can upload up to 4 reference photos.
Which Nano Banana model should I use?
Nano Banana 2.1 for most images and anything with in-image text, Nano Banana Pro for cinematic portraits and fine detail, and Nano Banana 2 for cheap, fast drafts.
Do I need words like "8k" or "masterpiece"?
No. Nano Banana models follow natural language, and resolution is a setting in the studio. Specific descriptions of the subject and light help far more than quality keywords.
