About This Tool
Adding a text watermark to a PDF helps you assert ownership, mark document status, or prevent unauthorised redistribution. Common uses include stamping a draft with "CONFIDENTIAL", overlaying "SAMPLE" across proposal documents before final approval, branding reports with a company name, or marking exam papers with the student ID to deter sharing.
JustConvert applies your custom text as a semi-transparent diagonal watermark covering every page of the document. You can choose to position it in the centre, at the top, or at the bottom. The watermark is embedded directly in the PDF structure and appears on every page without requiring any additional software to view it correctly.

Frequently Asked Questions
Can I choose different positions for the watermark? expand_more
Yes. You can place the watermark in the centre (diagonal), at the top centre, or at the bottom centre of every page. The diagonal centre position is the most common choice as it is clearly visible without completely obscuring the content.
Can the watermark be removed by the recipient? expand_more
A text watermark added this way is embedded in the PDF page content. It can be removed with specialised PDF editing software, but not by an average user. If you need a more secure solution, combine the watermark with password protection to prevent editing.
Does the watermark appear on every page? expand_more
Yes. The watermark is applied to every page of the document automatically. There is no need to set it up page by page.
Can I use my company name or logo as the watermark? expand_more
This tool supports text watermarks. You can enter any text, including your company name, website URL, or a custom message. Image watermarks (logos) are not supported in the current version.
Why should I watermark a PDF before sharing? expand_more
Watermarking deters recipients from redistributing confidential documents and makes it easy to trace the source of a leak. It also sets clear expectations — for example, a "DRAFT" watermark signals that the content is not yet final and should not be relied upon.
