Add Watermark to PDF

About the Add Watermark to PDF

Add Watermark overlays text like DRAFT, CONFIDENTIAL, or your company name diagonally across every page of your PDF. You can tune opacity, angle and font size so the mark is visible without overpowering the content.

How to use

1. Upload the PDF and type the watermark text (or upload a logo).
2. Adjust colour, opacity (20-40% works well), rotation angle and font size.
3. Click Apply & download.

Benefits & key features

• Mark drafts so reviewers can't mistake them for the final version.
• Brand a proposal or PDF portfolio with your logo on every page.
• Subtle diagonal stamps deter casual copying on leaked documents.
• All rendering is done locally — no watermarks from third-party services.

Pro tip

Use a light-grey (#c0c0c0) 45° diagonal watermark at 30% opacity for the cleanest 'draft' look that still lets readers enjoy the content.

Why choose toolsfy for PDF tools?

Cloud-based PDF editors ask you to upload sensitive invoices, contracts or passport scans to servers you will never see — and then offer a "premium" plan to remove watermarks they added themselves. toolsfy turns that model upside down: every PDF operation on this page runs locally in your browser using the same modern Web APIs Chrome, Edge and Firefox ship with. Your file never leaves the device, no account is required, and there is no artificial cap on pages or size.

Common use cases

• Lawyers and accountants cleaning up scanned bundles of evidence before a client meeting, without sending them through a third-party server.
• University students assembling a single submission-ready PDF from multiple chapters, diagrams and reference pages — on a laptop with flaky campus Wi-Fi.
• Small-business owners stripping metadata, rotating scans, or watermarking product manuals before sharing them publicly on their website.
