Built for speed, privacy, and clean results when you want to remove the standard visible Gemini logo.
Private by default
Images stay in your browser. No upload step, no waiting for a server job, no cloud storage required.
Lossless restoration
Unmark reverses the visible Gemini overlay instead of guessing with inpainting, so detail stays intact.
Fast workflow
Drop in a file, process it locally, and download the clean version in seconds.
Built for Gemini images
The workflow is tuned specifically for the standard visible Gemini star logo rather than generic watermark removal.
How Gemini watermark removal works
Gemini adds a visible star logo as an overlay. Generic image editing tools usually try to paint over it or guess the hidden detail. Unmark takes a more direct approach: it reverses the visible blend so the image can be restored more faithfully.
That is why this workflow is strongest on the standard visible Gemini watermark and why it behaves differently from Photoshop-style inpainting. It is solving a narrow technical problem instead of doing a broad image edit.
Visible watermark vs SynthID
Unmark targets the visible Gemini star logo only. It does not claim to remove invisible SynthID or other provenance signals. That distinction matters for both user expectations and trustworthy search visibility.
Best-fit scenarios
- Presentation decks and investor slides that need a clean visual corner.
- Design mockups and storyboards where branding overlays distract from the composition.
- Reference boards and creative planning docs that need a faithful source image.
- Batch cleanup workflows for creators comparing multiple Gemini generations.
Unmark vs other cleanup workflows
Compare the fastest way to remove the visible Gemini logo with manual editing, inpainting, and cropping.
| Workflow | Method | Privacy | Typical outcome |
|---|---|---|---|
| Unmark | Reverse alpha blending for the visible Gemini logo | Runs locally in the browser | Best fit when the standard Gemini watermark is present |
| Photoshop or inpainting | Guesses missing pixels with manual retouching or generative fill | Depends on tool and workflow | Useful for custom edits, but often slower and more artifact-prone for the Gemini logo |
| Cropping | Removes part of the frame to hide the corner logo | Local | Fast, but throws away composition and resolution |
Supported formats and limitations
PNG exports tend to be the cleanest input because they preserve the visible overlay more predictably. JPEG and WebP can still work, but heavy recompression may reduce precision around the logo area.
If the image has been resized, cropped, aggressively filtered, or edited after download, results may vary. In general, the closer the file is to the original Gemini export, the better the result.
Latest compatibility note
This page is maintained for the standard visible Gemini star watermark workflow currently supported on April 8, 2026. If Google changes the overlay shape, opacity, or export path, Unmark should update both the tool and the documentation quickly.
