How to Add a Watermark to a PDF

A text watermark is the fastest way to mark a document as a draft, sample, or confidential copy before you send it out — or to stamp your name across a file you're sharing publicly so it isn't reused without credit. MyPDFEasy lets you preview the exact placement before committing, and applies the watermark to every page automatically, all inside your browser.

Frequently Asked Questions

How do I add a watermark to a PDF for free?

Upload your PDF, type your watermark text, adjust the size, color, opacity, and angle, then click "Add Watermark & Download". It is completely free.

Will the watermark appear on every page?

Yes. The text watermark is stamped diagonally across the center of every page in the document.

Can I change the watermark color and transparency?

Yes. Pick from preset colors and use the opacity slider to make the watermark subtle or bold, and the angle slider to tilt it.

Does the watermark cover the text underneath?

A semi-transparent watermark sits over the content but keeps it readable. Lower the opacity if you want the underlying text to stay clear.

Is my PDF uploaded to a server?

No. MyPDFEasy adds the watermark directly in your browser using pdf-lib. Your file never leaves your device — guaranteed privacy.

Can I watermark a multi-page PDF?

Yes. The watermark is applied to all pages automatically, no matter how many pages the PDF has.
