概要

The Gemini API renders a small translucent ' ' badge in the bottom-right corner of every image it produces. If you want to reuse the art in a slide deck, a thumbnail, or a print piece without a competitor's logo stamped on it, you need the overlay gone cleanly, not a hacky rectangle crop that tosses away the composition's right margin.

This tool runs an AI watermark removal pass tuned for that overlay region. It detects the watermark envelope, then fills those pixels by sampling the surrounding texture. The output is the same image, same dimensions, same format (PNG), minus the badge. Nothing else is touched: no colour regrade, no resize, no recompression beyond the loss-free PNG round-trip.

Every upload is only read while we process it. The cleaned PNG is held only until you download it, then deleted. No account ties the upload to your identity, no log keeps the image bytes, and the Privacy page lists every byte that ever touches a disk.

Most images never leave your device. When you drop two or more images, we run a quick local pre-clean inside your browser first. Only the images that still carry a residual after that pass are sent to our server for the heavy clean-up model. The result table tells you which images were finished on your device and which ones were cleaned by us.

Pricing. Cleaning one image is free, no account, no signup. Cleaning two to fifty images at once uses the paid batch path. The cost is 1 credit per image, charged only for the images that needed our server. Sign in or buy a credit pack to start. Your download links stay valid for 15 minutes.

プライバシー

画像は使い終わったら消えます

We process your image on our side because running AI watermark removal on low-end laptops would still be too slow to feel snappy. Your upload is only held while we process it and is deleted the moment we send the result back. Nothing is saved, indexed, or used for model training. Full byte-level disclosures live on the Privacy page.
