Add text watermarks like DRAFT or CONFIDENTIAL
Add text watermarks to PDF documents
Marking a document with a visible watermark signals its status and protects its ownership. Our PDF watermark tool stamps custom text — "DRAFT", "CONFIDENTIAL", "SAMPLE", your name, or any label — across your document with full control over how it looks. Adjust the text, font size, color, transparency, rotation, and position, or enable Mosaic mode to repeat the watermark across the whole page for a stronger effect.
Watermarks are applied permanently to the PDF content, so recipients cannot simply delete them, which makes the tool a practical choice for sharing work-in-progress or sensitive previews. Processing is free, requires no account to start, and your file is automatically deleted from our servers after the job finishes.
How to watermark a PDF
- Upload your PDF document
- Enter the watermark text you want to apply
- Adjust position, size, color, transparency, and rotation
- Enable Mosaic mode to repeat the watermark across each page
- Click Process and download your watermarked PDF
Tips for best results
- Use "CONFIDENTIAL" or "DRAFT" for review copies you share.
- Keep transparency around 30-50% so the watermark is visible but content stays readable.
- A 45-degree rotation makes watermarks harder to crop out of the page.
- Combine with Protect if the document itself must also be password-locked.
When should you watermark a PDF?
Watermarks protect content and communicate status at a glance. Businesses stamp "CONFIDENTIAL" on proposals and financials before distribution; agencies mark drafts with "DRAFT" so reviewers know nothing is final; photographers and designers add names or logos to preview files; lawyers label privileged documents. A well-placed watermark travels with the file wherever it is forwarded.
How to add a DRAFT watermark
A DRAFT watermark tells every reader that a document is not final — exactly what you want on review copies, proposals and anything still being edited. Set the watermark text to "DRAFT", use a transparency of around 30-50% so the underlying text stays readable, and enable Mosaic if you want the label repeated across the page. Because the watermark is applied to the PDF content itself, recipients cannot simply switch it off: the status travels with the file even after it is forwarded or printed.
Watermarking a document, not just a PDF
Most searches for "watermark a document" really mean watermarking a PDF, since that is the format most documents are shared in. If your source is a Word, Excel or PowerPoint file, convert it to PDF first with our Office to PDF tool, then run it through the watermark tool. You can also watermark images — photos, scans and screenshots — with the Image Watermark tool, which works the same way on JPG, PNG, GIF and WebP files.
What to know before you start
The watermark is baked into the PDF, so keep the original unmarked copy if you might need it later. You control text, position, font size, color, transparency, rotation, and mosaic repetition. The tool is free on first use with no account; files are encrypted in transit and deleted automatically after processing.
Frequently asked questions
Can I add a "DRAFT" watermark to my PDF?
Yes — set the watermark text to "DRAFT", "CONFIDENTIAL", "SAMPLE", or any text you want. Adjust opacity for the perfect effect.
Does the watermark cover every page?
Yes — the watermark is applied to every page. You can enable "Mosaic" mode to repeat the watermark across each page.
Can I rotate the watermark?
Yes — set any rotation angle (0-360 degrees). Diagonal watermarks at 45 degrees are a popular choice.
How do I add a DRAFT watermark to a PDF?
Set the watermark text to "DRAFT", choose a transparency around 30-50% so the content underneath stays readable, and optionally turn on Mosaic to repeat it across the page. The watermark is baked into the PDF, so it stays with the file.
Can I watermark a Word document?
Convert the Word, Excel or PowerPoint file to PDF first with the Office to PDF tool, then watermark the resulting PDF. You can also watermark images directly with the Image Watermark tool.
Is this tool free?
Yes, all Docu Stop web tools are completely free to use with no hidden charges or credit card required.
Are my files private and secure?
Absolutely. Files are processed over encrypted connections and automatically deleted from our servers after processing. We never access, store, or share your documents.
What is the file size limit?
Uploads are limited to approximately 4.5 MB per request due to server constraints. For larger files, download the Docu Stop mobile app which supports documents of any size.
