About Add Watermark to PDF
This tool adds a text watermark to every page (or specific pages) of a PDF document. Upload your file, customize the watermark appearance, and download the result. Common uses include marking documents as CONFIDENTIAL, DRAFT, or COPY.
Customization Options
Control every aspect of how the watermark looks. Adjust the font size from 12 to 120 points, set the opacity to make it subtle or prominent, choose a rotation angle for diagonal placement, and pick any color using the color picker.
Selective Page Application
Apply the watermark to all pages at once, or switch to specific pages mode and enter the exact page numbers. This is useful when only certain pages of a document need to be marked, such as the first page of each section.
Related Tools
Use the Merge PDF tool to combine watermarked and non-watermarked documents. The PDF Page Reorder tool lets you rearrange pages before or after adding watermarks.

Frequently Asked Questions
What watermark text can I use?
You can type any text you want, or use the quick presets like CONFIDENTIAL, DRAFT, COPY, SAMPLE, or DO NOT COPY. The text is rendered directly onto the PDF pages.
Can I control how the watermark looks?
Yes. You can adjust the font size, opacity (transparency), rotation angle, and color. Choose between diagonal placement or centered text. A live preview shows how the watermark will appear.
Can I watermark only certain pages?
Yes. Switch to "Specific pages" mode and enter the page numbers you want. Use commas and ranges, like 1,3,5-8.
Are my files uploaded anywhere?
No. All processing happens in your browser. The PDF is modified locally and never sent to any server.
Will the watermark affect text selection?
The watermark is drawn as an overlay on each page. Existing text in the PDF remains selectable. The watermark text itself is embedded as drawn text on the page.
