Why Watermark a PDF?
A watermark labels a document at a glance. Stamp text like Confidential, Draft, or your company name across the pages to mark ownership, signal status, or discourage unauthorized reuse.
Mark Ownership
Stamp your name or brand across every page to claim the document.
Signal Status
Label files clearly as Draft, Confidential, or Sample at a glance.
Processed Locally
The watermark is applied in your browser with no upload required.
Watermark PDF FAQ
Is the watermark added to every page?
Yes. The text you enter is stamped across all pages of the PDF in one pass, so the whole document is labelled consistently. This is ideal for marking a file as Confidential, Draft, or Sample from cover to cover.
Can I watermark with text?
Yes. Type any text you want, such as your company name or a status label, and it is applied across the pages. Text watermarks are clear, lightweight, and keep the underlying document fully readable.
Is my PDF uploaded to add a watermark?
No. The watermark is applied entirely in your browser on your own device. Your file is never uploaded, so confidential drafts and internal documents stay completely private.
