Important Disclaimer: Watermarks like Google’s SynthID (embedded in images generated by Nano Banana Pro or Gemini’s image tools) exist to promote transparency and responsible use of AI-generated content. Removing them may violate Google’s terms of service, copyright laws, or platform policies — especially if the image isn’t yours or is used commercially without permission. This tutorial is for educational and personal fair-use purposes only. Always respect intellectual property rights and consider legitimate alternatives (e.g., Google’s paid Ultra plan for watermark-free exports). Proceed at your own risk.
TL;DR
You can remove the visible Gemini/Nano Banana watermark (the little sparkle/diamond logo) completely for free using Adobe Express’s crop or AI Remove/Spot Healing tool. The invisible SynthID watermark cannot be fully removed with free tools — only diluted slightly through editing/exporting. The whole process takes 5–15 minutes per image.
Key Takeaways
- Visible watermark → easily removed with cropping or Adobe Express free “Remove object” / Spot Healing tool
- Invisible SynthID → not fully removable without paid/specialized tools; editing only reduces detection confidence a little
- Adobe Express free tier works perfectly for this and lets you export without its own watermark if you avoid premium assets
- Always keep the original file and disclose AI origin when sharing
- Better long-term solution: pay for Gemini Ultra / Nano Banana Pro to get clean exports natively
Detailed Step-by-Step Tutorial
Step 1: Get Your Nano Banana Image
- Open Gemini (web or app) → Nano Banana
- Generate your image
- Download it (free tier includes visible watermark)
Step 2: Open Free Adobe Express
Go to adobe.com/express → Sign in with free Adobe account → “Start for free”
Step 3: Quickest Method – Crop It Out
- Upload your image
- Use the Crop tool → drag to exclude the bottom-right corner watermark
- Apply → Done (perfect for most images)
Step 4: Remove Visible Watermark with AI (When Cropping Isn’t Possible)
- In the left panel → Quick Actions → “Remove object” (or search “remove”)
- Brush over the Gemini sparkle logo
- AI automatically fills the area with surrounding pixels
- Repeat or use Clone Stamp if needed
Step 5: Export Without Adobe Watermark
- Click Download
- Choose PNG or JPG
- If it tries to add Adobe watermark → you probably used a premium template/element → undo and use only free assets, or toggle watermark off in settings
- Free basic edits export clean 99% of the time
Step 6: Verify
- Zoom in → no visible logo
- Optional: upload to Hive Moderation or ask Gemini “Is this AI-generated?” → invisible SynthID usually still detectable
Alternative Free Tools if Adobe Express Is Acting Up
- WatermarkRemover.io (4 free removals/day)
- Photopea.com (web Photoshop clone)
- Photoshop Express mobile app (free Spot Heal)
- GIMP (desktop, fully free)
My Thoughts on This Whole Thing
Google adding both visible and invisible watermarks is actually a good move for transparency — the problem is they lock clean exports behind the priciest Ultra tier. For hobbyists and educators who just want to use a nice AI image in a presentation or blog without an ugly logo in the corner, having to pay $20+/month feels excessive.
Adobe Express giving us a powerful, free “Remove object” tool essentially hands everyone a workaround for the visible mark, which is why this method works so well right now. The invisible SynthID is much harder to defeat without specialized (often paid or legally gray) tools, so for most practical purposes, the images are still identifiable as AI-generated — which keeps the transparency promise somewhat intact.
Ethically, I’m fine with individuals cleaning up images they generated themselves for personal or clearly disclosed use. The line gets crossed when people start stripping watermarks to pass off AI art as human-made photography or to sell commercially without disclosure.
Long-term, I hope Google adds a middle-tier plan that removes the visible logo (keep SynthID) for a few bucks a month — that would solve 95% of the frustration without undermining their transparency goals.
Until then… crop tool go brrr. 🐒
