Frequently Asked Questions
What is the Gemini Nano Banana watermark?
The Nano Banana watermark is a semi-transparent sparkle mark that Google Gemini adds to the bottom-right corner of AI-generated images. It appears as a subtle white star pattern.
How does the watermark removal work?
The tool uses reverse alpha blending to mathematically reconstruct the original pixels hidden under the watermark. No AI or machine learning is involved — it is a precise mathematical operation.
What image formats are supported?
Upload PNG, JPG/JPEG, or WebP images up to 20 MB. The output is always a lossless PNG for the best quality.
Are my images stored on your servers?
No. All processing happens in-memory and the image is discarded immediately after the cleaned version is returned to you.
Can I use this commercially?
Yes, as long as you have rights to the source image. The tool does not add any watermarks or restrictions to the output.
Is there a file size limit?
Yes, the maximum upload size is 20 MB per image. Most AI-generated images are well within this limit.
Does it work with watermarks from other AI tools like DALL-E or Midjourney?
No. This tool is specifically designed to remove the Gemini Nano Banana sparkle watermark. It will not work on watermarks from DALL-E, Midjourney, or other AI image generators.
What happens if my image does not have a Gemini watermark?
The tool will still process the image, but the result may look identical to the original or show minor artifacts in the bottom-right corner where it expects the watermark to be.
