Add Text Watermark to PDF: Complete Guide
Protect your documents or mark them as drafts with a custom text watermark. Our free tool overlays your chosen text — like “CONFIDENTIAL”, “DRAFT”, “SAMPLE”, or your company name — diagonally across every page of your PDF. You control the font size, color, opacity, and rotation angle. Watermarks are burned into the PDF so they appear when viewed, printed, or shared.
Text watermarks are widely used for: marking draft versions, indicating document classification (confidential/internal), branding sample documents, and deterring unauthorized copying. The watermark is applied as a semi-transparent overlay that doesn’t obscure the underlying content.

- Upload your PDF file using the tool above.
- Type your watermark text (e.g., “CONFIDENTIAL”).
- Adjust font size, color, opacity (transparency), and rotation angle.
- Choose position: diagonal center, top, bottom, or tiled across the page.
- Click “Add Watermark” and download your watermarked PDF.
Frequently Asked Questions
Will the watermark obscure my document text?
No. The default opacity is 30%, making the watermark visible but semi-transparent. You can adjust opacity from 10% (very faint) to 100% (fully opaque).
Can I remove the watermark later?
Watermarks are permanently burned into the PDF. Keep a copy of your original file if you may need a clean version later.
Does it work on scanned PDFs?
Yes. The watermark is added as a new layer on each page, so it works on both text-based and scanned (image) PDFs.
Are my files safe?
Yes. All processing is done in your browser. Files are never uploaded to a server.
Is there a limit on pages or file size?
No limits. The tool handles multi-page PDFs of any reasonable size, entirely free.
Best Practices to Add Text Watermark to PDF
When you add text watermark to pdf documents, choose wording that clearly communicates the document status. “DRAFT” prevents premature distribution, “CONFIDENTIAL” reminds readers of handling requirements, and “SAMPLE” protects your work from unauthorized use. Position the watermark diagonally across the center for maximum visibility without obscuring content.
For professional results when you add text watermark to pdf files, use 25-35% opacity. This keeps the watermark visible but ensures the underlying text remains readable. Our free tool lets you customize font size, color, rotation, and position to match your branding or compliance needs.

Remember that a watermark is a visual mark, not access control: anyone with the file can still read it, so never rely on a watermark alone to protect sensitive information. Add Text Watermark to PDF documents with that limit in mind, and share sensitive files only with people who should have them.
Add Text Watermark to PDF pages in small batches when files are long, and always keep an unwatermarked original, since a watermark burned into a page cannot be removed cleanly afterwards.
