Text to 4K image — describe anything and get a finished frame
Type a prompt describing your scene, subject, lighting, and style. Nano Banana 2 reads layered instructions — product placement, brand colors, in-image headline copy, artistic style — and returns a production-ready image. Native output reaches up to 2K, with seamless 4K upscaling. No account needed; open the Gemini app, pick the image tool, and generate.
- Native 2K output, upscales to 4K
- 95%+ in-image text accuracy across scripts
- 14 aspect ratios (1:1, 16:9, 9:16, and more)
- Supports photorealistic, illustration, anime, oil painting, and 3D styles
Image-to-image editing — change exactly what you describe
Upload a photo and tell Nano Banana 2 what to change in plain language. Swap a background to a city skyline, remove watermarks, restore faded colors in an old photo, or replace a clothing item with a reference shot. Only the part you describe moves — the rest of the scene stays intact. Works in the Gemini app and via the nano-banana-2 API endpoint.
- Surgical edits that preserve the unchanged scene
- Virtual clothing try-on for e-commerce
- Smart text and watermark removal
- Old photo restoration and colorization
Thinking mode — search, reason, and self-check before it renders
Nano Banana 2's thinking mode connects to real-time web data mid-generation. Ask it to build an infographic with live statistics, annotate a map with current details, or produce multiple image variants from a single prompt. It self-verifies the output before handing it back — useful for data-driven marketing visuals, storyboards, and campaign decks where facts must be right.
- Real-time web grounding via Gemini knowledge base
- Multiple images from one prompt
- Self-verification before final render
- Ideal for infographics, maps, slides, multi-panel storyboards

Text inside images actually renders correctly
Every prior AI image model struggled with text in images — garbled words, wrong fonts, broken multilingual copy. Nano Banana 2 fixes this. Posters, packaging, menus, infographics, signage — all come out with legible, pixel-sharp text on the first try. It handles Chinese, Japanese, Korean, Arabic, Hindi, and 100+ other scripts cleanly, even on curved surfaces and at small sizes.

4K output with real-world knowledge baked in
Nano Banana 2 pulls from Gemini's live knowledge base during generation. Ask for a poster featuring a specific landmark, a product shot next to a real street, or an infographic with current data — and the model places those elements accurately without extra prompt engineering. Output lands at native 2K and scales cleanly to 4K for print, digital, and high-res campaigns.

Keep characters and products consistent across a whole campaign
Lock a face, a product, or a brand element and generate dozens of variants without the subject drifting. Nano Banana 2 maintains up to 5 consistent characters and 14 detailed objects across a multi-image workflow. One briefing, one brand, any number of executions — whether you're building a social media series, a packaging line, or an A/B ad test.

Free in the browser, no account, no watermark
Most AI image generators gate 4K output behind subscriptions or credit walls. Nano Banana 2 is available free in the Gemini app and across third-party generators with no sign-up required. Commercial rights are included on most platforms. If you need to add text, brand elements, or a design layout on top of the generated image, drop it into Veeso AI to layer editable text without regenerating the whole frame.

Real scenes Nano Banana 2 handles on the first try
Marketing posters with legible headlines
Campaign art, product launch posters, event flyers — Nano Banana 2 renders the headline, subhead, and fine print crisp enough to hand straight to the media team. No Photoshop pass needed to fix garbled text.
E-commerce product photography
Generate studio-grade product shots on clean backdrops or styled scenes. Swap backgrounds with a text instruction, add lifestyle context, and keep the product sharp and accurate across every variant — without a photo studio day.
Packaging and menu mockups with multilingual copy
Bottles, pouches, boxes, restaurant menus — rendered with readable ingredient lists, brand marks, and multilingual label copy that survives zoom and print. Chinese, Japanese, Korean, and Arabic copy stays sharp even on curved surfaces.
Social media graphics and ad creative
Paid social variants for Instagram, Meta, and TikTok — same character, same product, dozens of headlines. Lock the hero asset and rotate copy across the variant set. Multi-image mode returns the full batch from one prompt.
Infographics and data visuals with real facts
Thinking mode pulls live data off the web and renders it cleanly inside charts, annotated maps, and dashboard frames. Great for investor decks, editorial social content, and any visual where the numbers have to be right.
Photo restoration and creative editing
Restore damaged or faded photographs with one text instruction. Remove scratches, colorize black-and-white images, enhance facial details — then keep editing by describing the next change. No Photoshop skills required.
designers and content creatorsが Veeso AI を選ぶ理由
I used to spend 20 minutes per product shot fixing garbled text in Photoshop. Nano Banana 2 gets the copy right the first time — even Japanese characters on a curved label. I download and ship straight to the client.
We run 30+ ad variants per campaign. Nano Banana 2 lets me lock the product and iterate headlines without touching the hero image. The character stays the same across every creative — that's not something any other free tool can do.
My client needed a full restaurant menu mockup in both English and Mandarin. I prompted Nano Banana 2 once, got both language versions back, and the Chinese characters were actually correct and legible. Saved me three hours of Illustrator work.

Open the Gemini app or a free online generator
Nano Banana 2 is live in the Gemini app (open the image tool from the Tools menu and select the model), in Google Search AI Mode, and on free third-party platforms like nanobanana2.app, easemate.ai, and nano-banana-2.dev. No account is required on most platforms. Developers can call the model directly as nano-banana-2 via the Gemini API in AI Studio or Vertex AI.
Write a detailed prompt — or upload a photo to edit
For text-to-image: describe the subject, lighting, style, any in-image text, and the mood. The more specific, the better — 'a flat-lay of skincare products on marble, with the brand name Glow in bold white serif type' beats 'a product photo'. For image-to-image: upload the photo and describe only what you want to change. Nano Banana 2 reads layered instructions and leaves the rest of the scene untouched.
Generate, refine, and download in 4K
Click generate and your image appears in seconds. Point at any element — a background, a piece of copy, a color — and describe the change to iterate without starting over. Download in PNG, JPG, or WebP at up to 4K. If you need to layer editable text, brand colors, or a multi-page layout on top of the image, import it into Veeso AI — every text block stays live so headlines and prices update without regenerating the scene.
