If you've used Gemini to generate images, you've probably noticed the small star logo that shows up in the corner. It's the watermark Google adds to mark images as AI-generated. This post covers a few ways to remove it, when each method works, and when it doesn't.
Quick note before anything else: only do this on images you own, created, or have permission to edit. The methods below are the same whether the watermark is a Gemini star or any other corner logo.
What the Gemini watermark actually is
Gemini (and the Nano Banana image model) drops a small logo in the corner of generated images. It sits on top of the picture as part of the final export. Because it's usually in a corner and fairly small, it's often sitting over a simple area like sky, a flat background, or open space. That detail matters a lot for how easy it is to remove.
There's also an invisible layer to be aware of. Google uses SynthID, which embeds a signal into the pixels that survives basic edits. Removing the visible star doesn't necessarily remove that signal. So "the watermark is gone" means the logo you can see is gone, not that the image is stripped of every trace of being AI-generated.
Method 1: Crop it out
The fastest fix is to crop the image so the corner with the logo is gone.
This works when the watermark is near the edge and you don't need that part of the frame. It fails when the logo sits over something you want to keep, or when cropping throws off the composition. You also lose some resolution since you're cutting pixels.
Steps:
- Open the image in any photo viewer or editor (even Preview on Mac or Photos on Windows).
- Use the crop tool and pull the edge in past the watermark.
- Export the result.
If the logo is tucked right into the corner and the framing can spare it, this is the cleanest option. No special tools needed.
Method 2: Photoshop or GIMP
If you can't crop without losing important parts of the image, an editor with content-aware fill or a clone tool is the next step.
Photoshop's content-aware fill works well when the watermark sits on a plain background, like sky or a blank wall. It gets harder when the mark covers hair, text, a product label, or a detailed pattern. GIMP's resynthesizer plugin does something similar for free, though it takes more fiddling.
Rough process in Photoshop:
- Select the watermark area with the lasso or marquee tool.
- Go to Edit, then Content-Aware Fill.
- Adjust the sample area if the fill looks off, then apply.
- Touch up with the clone stamp if there's a visible seam.
The tradeoff here is time and skill. A clean result on a busy background can take several passes, and the fix is only as good as your patience with it.
Method 3: A dedicated remover tool
If you don't want to crop or open Photoshop, a tool built for this specific job is usually faster, especially for more than one image at a time.
This is where Gemini Watermark Remover fits. It's a free browser tool made for removing the Gemini star logo. You upload the image, it processes, and you download the cleaned PNG. There's no signup and no credit system.
A few things worth knowing about it:
- The images are processed in your browser, so files aren't sent to a server or held in a queue. That's a reasonable thing to care about if you're handling client visuals.
- You can upload up to 20 images in one batch, which helps if you're cleaning a set of drafts at once.
- It accepts PNG, JPG, JPEG, and WebP, and exports high-resolution PNGs.
It's narrow on purpose. It's built for the Gemini logo specifically rather than trying to handle every watermark type, which is why it tends to keep the rest of the image close to the original.
Which method should you use
If the logo is in a corner you can spare, crop it. That's the simplest path and you don't need anything extra.
If cropping would cut something you need and you're comfortable in Photoshop or GIMP, use content-aware fill. You get the most control, but it costs time.
If you're cleaning several images or you just want it done without manual editing, a dedicated tool like the free remover handles the batch in one session.
A note on quality and limits
No method is magic. Removing a watermark from a detailed background will sometimes leave a faint trace, no matter which tool you use. Results depend on what's behind the logo. A star sitting on flat sky is easy. A star sitting across someone's hair is not.
And again, the visible logo is the part you're removing. The underlying SynthID signal is separate, so treat watermark removal as cleaning up the look of an image, not as a way to hide that it was generated.
