How to Use Watermark PDF: A Complete Guide
Stamping text like "CONFIDENTIAL" or a company name across every page, choosing opacity and angle that won't obscure content, and why it applies to the whole document.

Watermark PDF stamps text — "CONFIDENTIAL," "DRAFT," a company name — diagonally across the center of every page, drawn directly into the page content in your browser.
Step-by-step
- Upload your PDF.
- Enter the watermark text.
- Adjust font size, opacity, and rotation angle to taste.
- Download the watermarked file.
Choosing opacity and size
Low opacity keeps the underlying content fully readable while still marking the document — good for a "DRAFT" stamp on a document people still need to read closely. Higher opacity makes the watermark more prominent and harder to ignore, at the cost of making the page busier. A 45° rotation (the default) tends to read clearly across a page without lining up with normal horizontal text.
What to know before relying on it
The watermark applies to every page of the document — there's currently no option to watermark only specific pages. Only a text watermark is supported (no logo/image watermark yet), and the text color is fixed rather than customizable.
Troubleshooting
- "The watermark is too distracting." Lower the opacity — a subtle watermark still marks the document without competing with the content for attention.
- "I only want it on some pages." Not currently supported — the watermark applies uniformly to every page.
- "I need my logo, not text." Image watermarks aren't supported yet — use text for now.

Frequently Asked Questions
Can I watermark only some pages, not the whole document?
Not currently — the watermark is applied uniformly to every page.
Can I use a logo image instead of text?
Not currently — only a text watermark is supported.
Can I make the watermark subtle rather than bold?
Yes, the opacity slider lets you make it as faint or as prominent as you want.
Can the watermark be removed later?
The text is drawn directly into the page content, so it isn't removable through ordinary editing.
