Tampermonkey Gemini Watermark Remover Userscript

For Tampermonkey / Violentmonkey users. Auto-cleans supported Gemini previews, copies, and downloads locally — stay inside Gemini, no extra steps.

Preview, copy, and download cleaned images without leaving the Gemini page.

Images are processed in your browser. Nothing is uploaded to our servers.

Targets visible Gemini logo watermarks only. Does not affect SynthID or metadata.

Install in three steps

Add a script manager, install the .user.js file, then return to Gemini.

Install Tampermonkey or Violentmonkey in Chrome, Edge, or Firefox.

Click the install button on this page and confirm in your manager.

Supported images will be auto-cleaned on preview, copy, and download.

Tampermonkey or Violentmonkey?

Both work. Use whichever you already have, or pick Violentmonkey for an open-source option.

Does the userscript upload my images?

No. All processing happens locally in your browser.

Which browsers are supported?

Chrome, Edge, Firefox, and other browsers that support Tampermonkey or Violentmonkey.

How is it different from the Chrome extension?

The userscript is for people who already use a script manager. The Chrome extension is a standalone install from the Web Store.

Does it remove SynthID or invisible watermarks?

No. It only targets the visible Gemini logo watermark.

The watermark is still visible after install?

Refresh the Gemini tab, confirm the script is enabled, and try again. For unsupported cases, use the online tool or report on GitHub.

Install the userscript to clean Gemini images without leaving the page.
