Gemini & ChatGPT watermark removal walkthrough
This page hosts the official GPT Watermarker tutorial video. Use it to learn SynthID hidden-watermark removal, visible Gemini logo removal, and how free limits vs credits work before you upload your first image.
What this video covers
A full walkthrough of GPT Watermarker: how hidden SynthID and C2PA removal works on GPUs, how the visible Gemini sparkle logo is removed locally in your browser, what the free daily allowance includes, and when credits are charged.
Hidden watermark removal (SynthID & C2PA)
Gemini and ChatGPT images can carry invisible SynthID frequency signals and C2PA content credentials. The hidden-watermark mode queues your file server-side, processes it on GPUs (often several minutes per image), and returns a download when complete. You can close the tab and check History later.
Physical logo removal (Gemini sparkle)
Google Gemini stamps a visible sparkle in the corner using alpha blending. The physical-watermark mode reverses that blend in your browser — fast, free within your daily quota, and unlimited on an active subscription.
Pricing: free logo vs credits
Sign in to use any tool. Visible logo and metadata cleanup are free up to 10 per day (shared allowance). Hidden SynthID/C2PA jobs use 1 credit per image, charged only on success. Subscriptions lift the logo cap and include monthly credits.
