02 — How it works
Step 01
Use a JPG, PNG, WebP, MP4, WebM, MOV, or M4V. Your selected file stays in your browser.
Step 02
The engine checks known Gemini and Veo sizes, anchor positions, and watermark evidence before editing pixels or frames.
Step 03
Drag the exact comparison slider, review playback for video, then download a PNG or MP4. Weak evidence fails closed instead of forcing a risky edit.
03 — What it supports
The tool models documented visible Gemini sparkle and Veo watermark families in supported images and videos. It does not claim to remove SynthID, C2PA provenance, arbitrary logos, or ownership signals.

SynthID is an imperceptible signal embedded into AI-generated content. This tool removes only the supported visible corner mark. Provenance and disclosure responsibilities still apply.
Visible corner mark
