Why Nano Banana Images Have a Watermark
Google adds a small visible sparkle to images generated or edited with Nano Banana in the Gemini app, and also embeds an invisible SynthID watermark. This tool removes the visible sparkle so the image looks finished in a slide, thumbnail, mockup, or post.

Nano Banana Watermark FAQ
Answers about Nano Banana, Nano Banana Pro, SynthID, and free usage.
What is Nano Banana?
Nano Banana is the popular name for Google's Gemini image generation and editing model, Gemini 2.5 Flash Image. Nano Banana Pro is the name used for the newer Gemini 3 Pro Image model. Images you create with them in the Gemini app carry the same visible sparkle watermark in the corner.
Which watermark does this remove from Nano Banana images?
It removes the visible Gemini sparkle in the bottom-right corner. It does not remove SynthID, the invisible watermark Google embeds in the pixels, and it does not change image metadata.
Does it work for Nano Banana Pro images too?
Yes, as long as the image shows the standard visible Gemini sparkle in the corner. Use the original download rather than a screenshot so the corner is not resized or recompressed.
Can I use it on my phone?
Yes. Image cleanup runs in mobile browsers on iPhone and Android. Save the image from the Gemini app to your photos first, then pick it from the upload button.
Is it free?
You can clean 3 images a day without signing in, or 5 a day with a free account. Pro removes the daily limit and adds batch processing.
