PDF Watermark Tool – Free Online Tool
Add text or logo watermarks to PDF files locally with smart draft defaults, page ranges, opacity controls, and copyable sharing notes.
Free PDF Watermark Tool With No Uploads
ToolsMint PDF Watermark Tool helps you add text or logo watermarks to PDF files directly in your browser. Use it for confidential documents, draft reports, client previews, sample files, ebooks, contracts, invoices, and internal PDFs without sending the file to a server.
Add Text or Logo Watermarks to PDF
Create a text watermark such as CONFIDENTIAL, DRAFT, SAMPLE, PRIVATE, or DO NOT COPY, or upload a PNG/JPG logo watermark. You can adjust opacity, rotation, size, color, and layout so the mark is visible without making the document hard to read.
Smart Watermark Diagnostics
A faint or footer-only watermark can be easy to miss or crop. The built-in assistant flags low opacity, partial-page coverage, and crop-prone layouts, then offers practical draft defaults for faster sharing workflows.
Private PDF Watermarking for Everyday Work
Use the PDF watermark tool before sending drafts, proofs, contracts, HR documents, legal exhibits, school handouts, research PDFs, client samples, paid templates, and branded reports. The copyable summary records what was added and confirms the file stayed in the browser.

Frequently Asked Questions
Everything you need to know about the PDF Watermark Tool.
Is this PDF watermark tool free?
Yes. It is free to use with no signup, no watermark added by ToolsMint, and no account requirement.
Are my PDF files uploaded?
No. The PDF is opened, watermarked, and exported locally in your browser.
Can I add a logo watermark to a PDF?
Yes. Upload a PNG or JPG logo, choose placement, adjust opacity and size, then export the watermarked PDF.
Can I watermark only some pages?
Yes. Leave the page field blank for all pages or enter ranges such as 1, 3-5, 10.
What watermark layouts are supported?
You can use diagonal, centered, header, footer, and tiled layouts. Tiled and diagonal marks are harder to remove visually by simple cropping.
Does a watermark prevent copying?
No watermark is a complete security control. It helps label, brand, and discourage misuse, but use permissions, redaction, or access control for stronger protection.
