About CleanMark
We build free, privacy-first tools that make AI image processing effortless.
Our Mission
CleanMark was built to solve a simple problem: Google Gemini adds watermarks to AI-generated images, and there was no free, private way to remove them. We built CleanMark to change that.
We are passionate about making image processing effortless and transparent — helping creators, researchers, designers, and educators focus on their work rather than technical friction. CleanMark handles the watermark removal invisibly in the background, so you never have to think about it.
Our Values
Privacy First
All processing happens locally on your device. No images are uploaded, no data is collected, no tracking. Your files never leave your browser.
Completely Free
CleanMark is free forever — no plans, no limits, no hidden fees. We believe tools that help creators should be accessible to everyone.
Innovation Driven
We use reverse alpha blending and WebAssembly to deliver mathematically exact watermark removal in milliseconds — no AI inference required.
Accessible
Available as a Chrome extension for automatic removal and as an online tool that works in any browser without installation.
Open Source
CleanMark is open source. You can inspect the code, contribute, or build on top of it.
