Removing a different watermark
The tool above knows the Gemini watermark by heart. It can also learn a watermark it has never seen — any see-through logo that sits in the same spot on every picture, from any tool.
Add 3 or more pictures that share the same watermark (more is better — around 20 gives the sharpest result). Because the logo stays put while the pictures underneath differ, it can be told apart from your content and then removed the same exact way, restoring what was underneath rather than blurring it. As always, nothing is uploaded.
Removing the sparkle from a still image
Gemini puts its four-point sparkle in the bottom-right corner of every picture it generates, at a fixed size and position. That predictability is what makes a still image the easiest case: the mark can be undone rather than painted over, so the texture, edges and any text that sat under the logo come back as they were.
Use the tool above, or read the guide to the Gemini watermark first if you want to know what is being removed and what stays behind.
What to expect
- About a second per image, done entirely in this tab.
- A lossless PNG download, so nothing is re-compressed on the way out.
- No change anywhere else in the picture — the rest of the file is identical to what you put in.
- Nothing uploaded. The picture never leaves your device, which matters for client work and anything unpublished.
Getting the cleanest result
Download the original from Gemini rather than screenshotting it, and remove the watermark before you crop, resize or export to JPEG. Editing first moves and softens the mark, which makes the corner harder to restore perfectly. Working with video instead? Use the video watermark remover.
Where the sparkle causes the most trouble
A corner logo is harmless on a landscape and a real problem on anything tightly composed. The awkward cases are product shots where the badge lands on the item, portraits where it clips a shoulder or hair, and any render carrying text near the edge — a logo over lettering is immediately obvious if a tool blurs it rather than restoring it. Square and vertical crops make it worse, because a mark that sat safely outside the subject in a 16:9 frame moves inward as soon as the aspect ratio changes.
This is also why cropping the corner off is a poor fix: you lose real composition to hide something a few dozen pixels wide, and the invisible SynthID mark stays in the file regardless.
Before and after
The same corner of a Gemini image, straight from the model and after the watermark is removed. The detail underneath the logo comes back — it is not blurred over or patched with invented pixels.
How the removal works
Most watermark removers guess. They erase the area and ask an AI model to paint something plausible into the hole, which is why results so often look smeared, or invent detail that was never there. This tool does something different: it undoes the watermark instead of covering it up.
The sparkle is a semi-transparent layer blended over your picture, so every watermarked pixel is a fixed mix of two things — the logo, and whatever was underneath. Because the logo is identical in every Gemini file, that mix can be measured once and then reversed, pixel by pixel, to recover the original colour. The result is the detail that was actually behind the logo, not a plausible imitation of it.
Why that matters for quality
- Nothing outside the corner is touched. The rest of your image is passed through unchanged, so there is no global quality loss.
- No blur, no smearing. Textures, edges and text under the logo come back as they were.
- It refuses to guess. If the Gemini sparkle is not actually present, the file is returned exactly as you gave it, rather than having an odd bright patch stamped into the corner.
Files that were re-saved or re-compressed after watermarking — a JPEG export, a screenshot, or any video frame — no longer hold the exact original values, so a light extra pass tidies the logo's soft edge in those cases.
Image watermark questions
Which image formats work?
PNG, JPEG and WebP. The original PNG from Gemini gives the cleanest result because nothing has been re-compressed yet.
Will the rest of my image change?
No. Only the small corner holding the watermark is touched; every other pixel is passed through unchanged.
Does it work on a phone?
Yes. Images are quick even on a phone, since only the corner needs work.
Can I remove the watermark from several images at once?
Do them one after another — each takes about a second, and none of them leave your device.
