Common questions

How do I remove the Gemini watermark from an image?

Drop a Gemini export on Unmark. Instant cleans one image in your browser with no account. Cloud saves the result to your Library, supports bulk, and works with the Chrome extension.

What is the Gemini sparkle / stamp on images?

Google Gemini adds a small four-point sparkle watermark, usually in a corner of AI-generated images. Unmark is built specifically to remove that Gemini sparkle — not every generic watermark.

What’s the difference between Instant and Cloud?

Instant is free and private on this device — download only. It does not save to Library, run bulk jobs, or power the Chrome extension. Cloud uses credits and unlocks Library, bulk processing, and extension workflows.

Can I remove a Gemini watermark for free?

Yes. Instant mode cleans a single image in your browser with no sign-in. Sign up for Cloud when you want Library history, bulk cleanup, or the extension.

Yes. Unmark is optimized for common Gemini aspect ratios (16:9 landscape and 9:16 portrait) and keeps the original resolution when you download.

Yes. Unmark for Gemini pairs with Cloud — sign in on Unmark so extension jobs can use your credits and appear in Library. Instant browser mode does not connect to the extension.
