Check an image

Find out whether an image carries an AI-ID Center signature, and whether it has changed since it was signed.

Choose an image or drop it here You can check PNG, JPEG and WebP images. AI-ID signs PNG images.

Your image is checked in your browser. It is sent to us only if you choose to search for a watermark, and it is never stored.

About the watermark search: the watermark usually survives compression (JPEG, WebP), resizing and screenshots. It may be lost after heavy cropping (more than about 10% of the image) or rotation. If no watermark is found, this does not mean the image was not signed by AI-ID.
