Frequently Asked Questions

Why watermark a PDF?+

Watermarks discourage unauthorized reuse and make the document's status unmistakable — recipients instantly see it's a draft, a copy, or confidential material.

Can the watermark be removed later?+

It's embedded into the page content, so it can't be casually deleted like an annotation. It offers strong practical protection, though no watermark is cryptographically tamper-proof.

Does the watermark cover the text?+

It's rendered in semi-transparent gray behind readability — documents remain fully readable while the mark stays clearly visible.

Is my document uploaded?+

No — watermarking happens entirely in your browser, which matters since watermarked documents are usually the sensitive kind.
