About Unmark
A focused tool for removing the visible Gemini watermark
Unmark is built around one narrow job: helping creators clean the standard visible Gemini logo quickly, privately, and with realistic expectations about what the workflow can and cannot do.
What Unmark does
Unmark is designed for the visible Gemini star logo that appears on supported image exports. It is not a general-purpose provenance removal product, and it does not claim to remove invisible systems such as SynthID.
That product decision is intentional. A tighter scope makes it easier to explain the workflow honestly, set better user expectations, and publish documentation that is specific enough to be useful.
Who it is for
- Designers preparing mockups, storyboards, or concept boards.
- Founders and operators building decks or internal documents.
- Creators comparing batches of Gemini generations.
- Anyone who wants a simple browser-based workflow instead of manual cleanup.
How the workflow is framed
Step 1
Open the remover and choose a supported Gemini image.
Step 2
The visible logo is analyzed and reversed locally in the browser.
Step 3
You review the clean output and export the result for your design, presentation, or reference workflow.
Product principles
Narrow scope
Unmark focuses on the standard visible Gemini star logo instead of claiming to solve every watermark problem on the internet.
Private by design
The core cleanup workflow is intended to run in the browser so creators can process sensitive images without uploading them to a server.
Clear expectations
We try to explain what works, what does not, and how formats, resizing, and compression can affect the result.
Useful documentation
The blog exists to answer the real questions users ask about Gemini watermarks, SynthID, formats, and cleanup workflows.
How we maintain the guides
The blog and homepage copy are maintained around the supported Gemini watermark workflow visible on the site at the time of writing. When compatibility changes, the goal is to update both the product copy and the supporting documentation.
We prefer direct language over broad claims. If a limitation exists, we would rather explain it than hide it behind vague marketing copy.
Support and contact
Support requests, compatibility questions, and product feedback can be sent to support@unmark.app.
We aim to respond to product and compatibility questions within a few business days.
