Upload a screenshot, export, or original image to inspect metadata, transparency, and common browser-visible signals. The file stays on your device during analysis.

Start with a PNG, JPG, WEBP, GIF, or BMP image. This tool looks for common metadata and transparency clues, but it does not guarantee detection of every invisible watermark.
The checker focuses on signals you can inspect locally in the browser: EXIF blocks, PNG text chunks, authoring software fields, GPS presence, alpha transparency, and RGB channel previews. It is designed for fast privacy review before you share screenshots or exports.
Invisible watermarks are often platform-specific and may survive only under proprietary detection methods. A clean result here does not prove the image is free of hidden tracking marks, fingerprinting, or service-side identifiers.
This MVP is designed to run in the browser. The selected image is decoded locally to inspect metadata and render channel previews, so you can do a first-pass privacy check without sending the file to a remote server.
1. Upload a screenshot, exported image, or original file. 2. Review the metadata and risk summary first. 3. Check whether alpha transparency or PNG text chunks exist. 4. Compare the RGB channels if you suspect extra marks or patterns. 5. If needed, re-export the image and test the cleaned copy again.
Most consumer screenshots do not expose every embedded signal in a way that a browser tool can verify. The useful job of this page is to catch obvious metadata leaks, transparency layers, and suspicious authoring traces before you share a file, not to promise a perfect yes-or-no watermark verdict.
