Nano Banana 2 Lite: Complete Guide — How to Use, Prompts, Settings & Tips (2026)

This is the definitive guide to using Nano Banana 2 Lite — Google's fast AI image generation and editing model. Whether you are a first-time user or looking to get better results, this guide covers everything: what the model can do, how to use it step by step, the best prompt techniques, how to choose settings, pricing details, and advanced tips for professional-quality output.

What Is Nano Banana 2 Lite?

Nano Banana 2 Lite is the codename for Google's Gemini 2.5 Flash Image model. It is a lightweight AI image model optimized for speed and cost efficiency. The name "Nano Banana" originated as an internal codename at Google and stuck in the AI community.

Nano Banana 2 Lite sits in a family of Google image models:

Nano Banana 2 Lite (Gemini 2.5 Flash Image) — Fast, affordable, great for everyday use. This is what we cover in this guide.

Nano Banana Pro (Gemini 3 Pro Image) — Higher quality, slower, more expensive. Better for commercial work with demanding quality requirements. See our detailed comparison.

Imagen 4 — Google's older image model, now deprecated and shutting down August 17, 2026. If you were using Imagen 4, Nano Banana 2 Lite is the recommended replacement.

You can use Nano Banana 2 Lite through Google AI Studio (free with watermarks and daily limits) or through dedicated platforms like NanoBananaLite2 that offer a cleaner interface, no watermarks, and higher resolution output.

Text-to-Image vs Image-to-Image: Which Mode Should You Use?

Nano Banana 2 Lite supports two modes of image creation. Understanding when to use each one is the single most important thing for getting good results.

Text-to-Image

You write a text prompt describing what you want, and the AI generates an image from scratch. No source photo needed.

When to use text-to-image:

You want to create something entirely new — a scene, a character, a product concept, or an abstract design. You do not have a reference photo to work from. You want maximum creative freedom where the AI interprets your description.

Example prompt: "A cozy Japanese ramen shop at night, warm lantern light spilling onto a wet cobblestone street, steam rising from a bowl visible through the window, cinematic photography style, shallow depth of field."

Image-to-Image

You upload one or more source photos, write a prompt describing what changes you want, and the AI modifies the image while preserving key elements (like a person's face, an object's shape, or the overall composition).

When to use image-to-image:

You want to transform an existing photo — change the style, swap the background, turn yourself into an action figure, create a figurine version, apply an artistic filter, or edit specific elements. You want the output to resemble a real person or object from the source photo.

Example prompt (with uploaded selfie): "Transform this person into a collectible action figure inside a sealed retail blister pack box with transparent plastic window, cardboard backing, and three miniature accessories."

The key difference: Text-to-image creates from imagination. Image-to-image transforms from reality. For most users, image-to-image is where Nano Banana 2 Lite truly shines — its ability to preserve a person's likeness through dramatic style changes is among the best of any AI image model.

Multi-Reference Image Editing

NanoBananaLite2 supports uploading up to 5 reference images simultaneously in image-to-image mode. This is a powerful feature that most platforms do not offer. You can upload:

A portrait photo plus a reference outfit photo to dress the subject in specific clothing. A face photo from multiple angles to help the AI capture your likeness more accurately. A photo of a person plus reference images of a specific art style, background, or prop.

The AI blends all reference images according to your text prompt. This is especially useful for action figure generation (upload your face plus a reference figure style), product mockups (upload your product plus a lifestyle setting), and character consistency across multiple images.

How to Use Nano Banana 2 Lite on NanoBananaLite2

Step 1: Sign In

Go to nanobananalite2.com and sign in with your Google account. This takes about 3 seconds — no separate registration, no email verification.

Step 2: Buy Credits

Nano Banana 2 Lite on NanoBananaLite2 uses a credit system. Each image generation costs 5 credits. The smallest pack is $1.99 for 25 credits (5 images). See the full pricing breakdown below.

Step 3: Choose Your Mode

Switch between "Text to Image" and "Image to Image" tabs at the top of the creation interface.

For text-to-image, you only need to write a prompt. For image-to-image, click the upload area to add your source photo (and optionally up to 4 more reference images).

Step 4: Write Your Prompt

This is where the magic happens. See the prompt writing section below for detailed techniques. The short version: be specific, include style keywords, describe lighting, and mention the desired output format.

Step 5: Choose Settings

Aspect ratio: Pick the shape that matches your intended use. 1:1 for profile pictures and Instagram posts. 16:9 for YouTube thumbnails and desktop wallpapers. 9:16 for Instagram Stories and phone wallpapers. 4:3 for presentations. 3:4 for action figure boxes and portrait prints.

Resolution: Higher resolution means more detail but uses the same number of credits. Choose 1K for quick drafts and social media. Choose 2K for general-purpose output. Choose 4K for prints, zoom-in detail, and professional use. Start with 1K while iterating, then regenerate your favorite result at 4K.

Step 6: Generate and Iterate

Click the generate button and wait — most images arrive in 30 to 60 seconds depending on resolution and complexity. Review the result. If it is close but not perfect, refine your prompt and regenerate. Most users need 2-4 iterations to get a result they love.

Writing Effective Prompts

The quality of your output depends almost entirely on the quality of your prompt. Here are the techniques that consistently produce the best results with Nano Banana 2 Lite.

Be Specific, Not Vague

Bad: "A woman in a city."

Good: "A young woman with short black hair wearing a yellow raincoat, standing at a crosswalk in downtown Tokyo at dusk, neon signs reflecting in puddles on the wet pavement, shot from a low angle, 35mm street photography style."

Every detail you add gives the AI more to work with. Specify: the subject (who or what), the setting (where), the time (when), the mood (lighting, weather, atmosphere), and the style (photography type, art medium, reference artist).

Use Style Keywords

Style keywords dramatically change the output. These are the most effective ones for Nano Banana 2 Lite:

Photography styles: cinematic photography, studio portrait, street photography, product photography, macro photography, drone aerial shot, film photography, Polaroid style.

Art styles: digital illustration, watercolor painting, oil painting, anime style, pixel art, vector illustration, pencil sketch, concept art.

Lighting keywords: golden hour lighting, dramatic side lighting, soft diffused light, neon lighting, rim lighting, natural window light, studio lighting with softbox.

Quality keywords: 8K detail, photorealistic, hyper-detailed, sharp focus, professional quality, award-winning photography.

Structure Your Prompts

A reliable prompt structure for Nano Banana 2 Lite follows this pattern:

[Subject] + [Action/Pose] + [Setting/Background] + [Lighting] + [Style] + [Quality modifiers]

Example: "A golden retriever puppy [subject] sitting and looking up with big eyes [action] in a sunlit meadow with wildflowers [setting] during golden hour with warm backlight [lighting] shot in shallow depth of field 85mm portrait style [style] ultra-detailed 4K [quality]."

Image-to-Image Prompt Tips

When editing an existing photo, your prompt should describe the desired change, not the entire scene. The AI already sees the source image — you just need to tell it what to modify.

Bad: "A person standing in a room wearing clothes with a face."

Good: "Transform into a collectible vinyl art toy with glossy PVC finish, inside premium minimalist packaging with gold foil accents."

For action figures and figurines, include packaging details (blister pack, box type, accessories). For style transfers, name the target style explicitly ("in the style of Studio Ghibli anime" or "as a GTA loading screen illustration"). For background swaps, describe only the new background ("place in front of the Eiffel Tower at sunset").

Resolution Guide: When to Use 1K, 2K, and 4K

Nano Banana 2 Lite on NanoBananaLite2 supports three resolution tiers. Choosing the right one saves you time without sacrificing quality where it matters.

1K resolution (1024px): Best for rapid iteration, social media posts, messaging stickers, quick concepts, and any situation where you are still experimenting. Fastest generation time. Use this 80% of the time while exploring ideas.

2K resolution (2048px): Best for final social media posts, blog images, presentation slides, and web graphics. Good balance of quality and speed.

4K resolution (4096px): Best for printing, zoomed-in detail shots, professional portfolios, commercial work, and any output where people will look closely. Longest generation time. Use this for your final chosen design, not for exploration.

Pro tip: Always iterate at 1K first. Once you have a prompt and result you like, regenerate that exact prompt at 4K. This saves credits and time compared to iterating at 4K from the start.

Best Use Cases for Nano Banana 2 Lite

Based on our testing and user feedback, these are the scenarios where Nano Banana 2 Lite delivers the best results:

AI action figures and figurines. This is the viral use case. Upload a selfie, describe a figure style, and get a realistic-looking collectible toy version of yourself. The model excels at preserving facial features while transforming everything else. See our action figure generator for ready-to-use prompts.

Style transfers. Turn a photo into anime, oil painting, watercolor, pixel art, GTA style, Studio Ghibli style, or any other artistic style. Image-to-image mode with a clear style keyword produces excellent results.

Product mockups. Upload a product photo and describe a lifestyle setting. The AI places your product in a realistic environment — on a marble countertop, in a model's hand, on a store shelf. Great for e-commerce listings and social media ads.

Profile pictures and avatars. Generate professional-looking headshots or creative avatars from a casual selfie. Describe the desired background, lighting, and style.

Social media content. Text-to-image generation for Instagram posts, blog headers, YouTube thumbnails, and story content. Each image takes under a minute, making it practical for regular content creation.

Background replacement. Upload a portrait and describe a new background. The AI swaps the background while keeping the subject perfectly preserved. No manual masking needed.

Use Cases Where Other Models Are Better

Nano Banana 2 Lite is not the best choice for everything. Here is when to consider alternatives:

Readable text in images: If your image needs clearly legible text (posters, infographics, logos with text), GPT Image 2.0 via ChatGPT is currently the leader in text rendering accuracy. Nano Banana 2 Lite sometimes garbles small text.

Artistic concept art: For maximum artistic quality in fantasy, sci-fi, or concept art, Midjourney still produces more visually striking and stylistically consistent results.

Layer separation: If you need editable layers (transparent PNGs of individual elements), Seedream 5.0 Pro is the only model that does this natively. See our comparison.

Free casual use: If you only need AI images for Instagram and WhatsApp and do not care about resolution or editing control, Meta Muse Image is free. See our comparison.

Advanced Tips

Negative prompting: Nano Banana 2 Lite responds to negative instructions. If your output consistently includes something you do not want, add "no watermarks" "no text overlay" or "without glasses" to your prompt.

Seed consistency: If you get a result you like but want slight variations, use the same prompt with minor tweaks. While NanoBananaLite2 does not expose a seed parameter, using very similar prompts tends to produce stylistically consistent results.

Batch workflow: When creating a series of related images (product line, content calendar, character set), write one master prompt, generate the first image, then modify specific elements for each variation. This maintains visual consistency across the series.

Combining with Canva or Figma: Generate your base image with Nano Banana 2 Lite at 4K, then import into Canva or Figma for text overlay, branding, and final composition. This gives you AI generation quality with precise design control for the finishing touches.
