Frequently Asked Questions (FAQ)

Is my document metadata or content safe?

Yes, 100%. This tool operates entirely under a client-side architecture. When you drop your PDF file, it is modified entirely within your web browser's local memory footprint. Absolutely no information is transmitted to external servers, making it perfectly safe for corporate or legal papers.

Will adding a text watermark distort my document layout?

Not at all. The underlying text, vectors, images, and formatting configurations remain completely intact. The watermark is applied seamlessly as an independent layer stamped cleanly on top of your existing page coordinates.

Can I choose how transparent the text is?

Yes, you can use the integrated opacity slider to dial in the perfect visibility balance, ensuring your safety stamp is visible without blocking the readability of the document text underneath.
