A Guide to Text and Image Generation with Nano Banana
Welcome to the cutting edge of AI creativity. Our Nano Banana Image Generator is a powerful tool that taps into Google's Gemini models to let you create and manipulate images in two primary ways: text-to-image and image-to-image generation. Whether you're starting with a blank canvas or an existing picture, this guide will walk you through how to get the best results.
Text-to-Image Generation: Creating from Words
Text-to-image is the process of generating a completely new visual based on a written description. This is perfect for when you have an idea but no starting image.
How it Works: Simply describe the image you want to create in the prompt box. The more detailed your description, the better the result. Our tool sends your prompt to a powerful model (like Imagen 4) which then interprets your words and creates a visual representation. For best results, use our Nano Banana Prompt Generator to craft detailed, effective prompts.
Image-to-Image Generation: Editing with Prompts
Image-to-image generation (or image editing) is where things get really exciting. This process allows you to upload one or more images and use a text prompt to modify them. You can add elements, remove objects, change the style, or even combine multiple images into a new composition.
How it Works: Upload an image using the file selector. Then, write a prompt that describes the changes you want to make. For example, you could upload a picture of a cat and use the prompt, "place this cat in a futuristic cyberpunk city." Our tool will send both the image and your text prompt to the Gemini 2.5 Flash Image model, which will then generate a new image based on your instructions.
