PDFs are the standard for sharing important documents because they preserve formatting across devices. But sharing sensitive information-like business plans, unreleased manuscripts, or legal drafts-comes with the risk of unauthorized distribution. Stamping your document with a "CONFIDENTIAL", "DRAFT", or custom logo watermark is the simplest way to establish document ownership and deter leaks.
Text vs. Logo Watermarks for PDFs
- Text Watermark: Best for internal documents. You can stamp words like "CONFIDENTIAL", "DO NOT COPY", or "DRAFT" diagonally across every page.
- Logo Watermark: Best for brand identity. You can overlay your company's transparent PNG logo in the background of official whitepapers or reports.
How to Watermark a PDF for Free Using EveryTool
EveryTool provides a free, browser-based utility that lets you stamp custom watermarks onto your PDF in seconds without registering.
- Open the Add Watermark to PDF tool on EveryTool.
- Upload your PDF file.
- Choose the type of watermark: Text or Image.
- If Text: type your word, choose a bold font, set the rotation angle (e.g., 45 degrees), and adjust opacity.
- If Image: upload your transparent logo file and adjust its opacity.
- Click the Apply Watermark button and download your protected PDF.
Set the opacity to between 20% and 40%. A good watermark should be clearly visible but fully transparent so that it doesn't make the PDF text unreadable.
We Respect Your Data Privacy
If you are watermarking a document, it's probably because the contents are sensitive. The last thing you want to do is upload a secret business plan to a random server. EveryTool processes your PDF entirely locally within your web browser. No copy of your watermarked PDF or your original file is ever transmitted to us.
