Over the past few weeks, I’ve been experimenting a lot with Google Gemini to generate content for my web projects. The quality of the images is impressive, but one thing has bothered me from the start: the visible watermarks and the invisible digital traces (SynthID, C2PA data) embedded in these images.
As someone who values digital self-determination, I didn’t want to use cloud solutions that require me to upload my images to third-party servers just to get them «clean.» That’s why I took matters into my own hands.
What is GWM Remover?
GWM Remover is a WordPress plugin I developed that focuses entirely on privacy. It doesn’t just remove the visible Gemini watermarks; it also deletes all metadata (EXIF, C2PA, SynthID traces)—all locally in your browser.
Why this plugin is different:
The core of my plugin is the principle of local processing:
- No Server Upload: Image processing takes place entirely in your RAM using the HTML5 Canvas API. Your server never even sees the images.
- Reverse Alpha Blending: I use a mathematical masking technique to precisely calculate and remove the watermark layer from the images, rather than just «painting over» them.
- Performance: Since the user’s CPU does the heavy lifting, your WordPress backend remains performant and lean.
My contribution to the community
I am a huge fan of the open-source philosophy. Therefore, I didn’t just build this plugin for my own workflow; I am also making it available as an open-source project on GitHub.
If you run a WordPress blog and value clean, metadata-free images, feel free to download the plugin and give it a try.
