AI Image Generation Revolution! Google Nano Banana Pro Supports 4K One-Click Translation for Korean and Japanese

Google has launched the latest generation AI image creation tool, Nano Banana Pro. The Pro version targets professional creators, designers, and enterprise users, supporting up to 4K resolution, precise text rendering, and the ability to merge up to 14 reference images at once. Most notably, its photo translation feature allows one-click translation of text within images into multiple languages such as Korean and Japanese, making it the most accurate AI image tool for Japanese translation.

Five Core Upgrades of Nano Banana Pro

Compared to the first-generation Nano Banana, which went viral on social media for turning selfies and pet photos into ultra-realistic 3D miniatures, Nano Banana Pro offers higher resolution, precise text rendering, and, for the first time, integrates real-time world knowledge for “studio-level” precision control. According to the official introduction, the main highlights of this AI image creation tool include:

Comprehensive Technical Specification Upgrades

· Supports up to 4K resolution and multiple aspect ratios (including 16:9, 9:16, etc.)

· Greatly improved text rendering, able to accurately present highly readable fonts and handwritten styles in multiple languages

· Can merge up to 14 reference images at once or maintain the appearance consistency of up to 5 characters

· Supports advanced camera controls (angle, depth of field, focus, lighting, tone)

· Built-in Google Search real-time knowledge, able to generate images based on real data such as weather, recipes, game scores, etc.

For usage, the free version can be accessed by selecting “Create images” directly on the Google AI web version and app, but with a daily quota; after exceeding the quota, it automatically reverts to the first-generation Nano Banana. Paid Google AI Pro and Ultra subscribers enjoy higher quotas, Ultra users can remove watermarks, and use the tool in products like Google Search AI Mode, NotebookLM, Google Slides, Ads, etc. API and Google AI Studio access have been opened for enterprises and developers.

Highlight 1: Clear Text Generation Changes the AI Image Creation Game

DeepMind provides specific AI image creation examples on their official website, with the first highlight being clear text generation. The text is sharp, fonts can be specified, and even handwritten styles can be simulated, making it suitable for posters, product mockups, and professional presentations. This feature overcomes the biggest pain point in text rendering for previous AI image tools—tools like Midjourney or DALL-E often produced blurry, distorted, or unrecognizable text.

The official prompt example: “Present a vibrant and eye-catching ‘TYPOGRAPHY’ font design on a textured off-white background. Letters should be bold, blocky, ultra-condensed, with overlapping layers of bright blue and magenta to create a 3D effect; each layer has a halftone dot texture for a retro print feel. Aspect ratio 16:9.” The resulting image has each letter clearly distinguishable and color layers distinct, fully reaching professional design standards.

This precise text rendering capability makes Nano Banana Pro an invaluable assistant for designers, allowing high-quality visual drafts to be quickly produced for everything from product packaging mockups to event poster design. Importantly, this ability is not limited to English; it also offers good support for complex scripts such as Chinese, Japanese, and Korean, marking an important step toward practical AI image creation tools.

Highlight 2: Photo Translation Feature Rivals the Most Accurate Japanese Translation Services

Nano Banana Pro’s photo translation feature is one of its most groundbreaking aspects, enabling one-click multi-language translation of text within images to quickly produce international versions of posters and product renders. In an official demo, the prompt “Translate all English text on the three yellow and blue cans into Korean, keeping everything else unchanged” resulted in the AI image tool perfectly preserving the design, color, and layout of the cans, only changing the text from English to Korean, matching the professional standard of recommended Korean translation agencies.

Even more impressive is the multilingual localization demo. The official prompt first asked to “Create a poster ad for a sparkling water brand called ‘Aura Fizz.’ Scene set at dusk, neon lights flickering on the streets of London. Slogan should be ‘Taste the Aura.’ Can design should be minimalist. Aspect ratio 16:9,” generating an English version. Then, “Localize this concept to a Japanese scene, keep the can design identical, and accurately and naturally translate ‘Taste the Aura’ into Japanese.” Nano Banana Pro not only changed the scene from London to Japan but also translated the slogan into the most accurate Japanese, with font style matching Japanese aesthetics.

A third prompt, “Localize this concept to a Mexican scene, keep the can design identical, and add the appropriate translation,” again changed the scene to reflect Mexican style and translated the text into Spanish. This photo translation ability is extremely valuable for brands promoting in international markets—tasks that used to require separate designers and translation agencies for each country can now be handled at once with Nano Banana Pro’s AI image creation feature.

Highlight 3: Real-World Knowledge Integration Creates Practical Value

Nano Banana Pro combines deep reasoning with real-time search capabilities, allowing images to be annotated, data to be turned into infographics, and notes into charts. In an official demo, the prompt “Create a high-quality top-down flat-lay photo infographic to simply explain how solar energy works,” along with a Wikipedia link to solar energy, resulted in an educational, modern, and easy-to-understand infographic.

This ability transforms AI image creation from a pure art tool into a knowledge visualization tool. Educators can quickly turn complex scientific concepts into visual charts, businesses can turn dull data reports into engaging infographics, and content creators can add precise illustrations to articles. Importantly, these images are generated based on real knowledge and data, not pure imagination, greatly enhancing usability and credibility.

Another demo—“Create an infographic showing how to make Elaichi Chai (cardamom tea)”—led Nano Banana Pro to generate a complete instructional graphic with ingredients, steps, and finished product. This feature is highly valuable for recipe websites, educational platforms, and product manuals. The built-in Google Search real-time knowledge allows Nano Banana Pro to generate images based on real-world data like weather, recipes, and sports scores, a unique advantage over other AI image tools.

Highlight 4: Complete Design Workflow from Sketch to Final Product

Nano Banana Pro’s fourth highlight is its design, stylization, and standardization capabilities, able to turn casual doodles into complete products, sketches into 3D objects, and concept text into finished architectural renderings. In an official demo, the prompt “Turn this simple sketch into a realistic car, following the creative direction of the sketch and using the colors and textures from the uploaded image” resulted in a simple car line drawing being transformed into a realistic 3D-rendered car.

Even more impressive is the style consistency control. The next prompt, “Turn this simple sketch into a realistic chair, following the creative direction of the sketch and using the colors and textures from the car image,” led the AI image tool to produce a chair that perfectly inherited the car’s color scheme and material style, achieving unified design language across objects. This is extremely valuable for product designers, who can quickly validate concepts and maintain brand visual consistency.

This AI image capability—from sketch to final product—shortens the design cycle and reduces prototyping costs. Designers can quickly iterate multiple design options at an early stage, and clients can see visuals close to the final effect before actual production, greatly improving communication efficiency and decision quality. Nano Banana Pro can merge up to 14 reference images at once, or maintain the appearance consistency of up to 5 characters, providing strong support for complex design projects.
