Whether you're marking a document as Confidential, adding copyright information, or promoting your business, this tool helps you create professional-looking PDFs without installing any software.
Why Add a Watermark to a PDF?
Watermarks make it easier to identify document ownership and communicate important information before a file is shared. Businesses often use them to display company branding, while freelancers, authors, and designers use them to protect digital content. They're also useful for labeling documents as drafts, samples, or internal-use only.
Example: A consulting firm can automatically stamp every proposal with its company logo, while an author can add a subtle copyright notice across each page before distributing an eBook.
How to Add a Watermark to a PDF

What You Can Customize

Popular Ways to Use PDF Watermarks
- Protect copyrighted documents before sharing them online.
- Add your company logo to proposals, invoices, and business reports.
- Mark files as Draft, Confidential, or For Review.
- Brand digital products such as eBooks, templates, and guides.
- Identify internal documents distributed within an organization.
Things to Know Before Watermarking
Watermarks become part of the exported PDF once the document is processed. If you later decide to remove or change the watermark, you'll generally need the original unwatermarked file or use a separate watermark removal tool. For the best appearance, use transparent PNG logos and avoid placing watermarks over important text or graphics.
Tips for Professional Results
Choose a watermark that is visible without making the document difficult to read. A light gray logo with moderate transparency often works well for reports and contracts, while bold diagonal text such as CONFIDENTIAL or DRAFT is better suited for internal documents. If you're adding a business logo, use a high-resolution image to ensure it remains sharp in the final PDF.
