If you want to swap faces between two images quickly and seamlessly, NanoBanana Pro is one of the easiest tools to use. With just a few clicks, you can upload two portraits, provide a prompt, and generate a realistic face swap in minutes. Here’s a detailed step-by-step guide to get you started.
The Google official Nano Banana Pro service is currently very congested — especially for free users, who are limited to only three generations at lower resolution.
If you don’t want to pay for the expensive official plans — you can try GlobalGPT instead. As an all-in-one AI platform, it fully integrates Nano Banana Pro with no usage limits, all at around 30% of the official price. Besides Nano Banana Pro, you can also use MJ, ChatGPT Image, and more than 20 other models to generate images.
On the video side, you can use Sora 2 Pro, Veo 3.1, and other models to turn images into stunning videos. In addition, GlobalGPT lets you leverage the latest advanced models like GPT-5.2, Gemini 3 Pro, and Claude 4.5 — all in one place, covering your entire AI workflow.

Step 1: Access the NanoBanana Tool
To begin using NanoBanana Pro, navigate to the tool page. Once there, you’ll see a clean interface designed for simplicity, making it easy even for beginners to perform face swaps without prior editing experience.
Step 2: Upload Two Portrait Images
Click the upload button to select two images you want to swap faces between. Ensure that both images are clear, well-lit, and face-forward for the best results. The AI works best with high-resolution portraits where faces are unobstructed.
Step 3: Write a Prompt for FaceSwap
After uploading your images, you need to write a prompt describing how you want the face swap to appear. This could be as simple as “swap faces between the two photos” or include style instructions like “make it realistic and seamless.” Clear prompts help the AI generate better results.
Prompt example：
“Replace the face in the first uploaded image with the face from the second uploaded image. Preserve the original expression, lighting, and background of the first image, and ensure the swapped face looks natural and realistic.”
Step 4: Click the Generate Button
Once your images are uploaded and your prompt is ready, simply click the Generate button. NanoBanana’s AI will process your images and create a new photo with the swapped faces. This process usually takes only a few seconds to a minute, depending on image quality and size.
Step 5: Download and Use Your FaceSwap Image
After generation, preview your swapped image. If satisfied, download it to your device. You can now use the face-swapped image for social media, memes, videos, or creative projects. NanoBanana ensures the final result looks natural and polished.
