Add Watermark to PDF

Puts semi-transparent text such as CONFIDENTIAL or DRAFT, or a logo image, on every page or on selected pages of a PDF and saves a new PDF. Use it to mark documents you send out or to show that a document is a draft.

How to use

1. Drop the PDF file onto the page or click to choose it.
2. Under "Watermark", choose "Text" or "Image or logo". For text, pick one of the "Common phrases" or type your own in "Text".
3. Set the "Opacity", "Angle" and size, and choose "Once per page" or "Repeat across the page" under "Layout".
4. Choose "Apply to" and "Layer", check the preview and press "Add watermark and save PDF".

How it works

• Text watermarks are drawn as a picture before they are added, so letters of many languages can be used, including Korean and Chinese.
• "Behind the content" keeps the text easier to read, but the watermark is hidden on pages with an opaque background, such as scanned pages.
• "Relative to each page" keeps the same proportion on pages of different sizes. The file is processed on this device only, and PDFs locked with a password or against changes cannot be opened.

Questions and answers

How do I add a CONFIDENTIAL watermark to a PDF?

Add the PDF and press CONFIDENTIAL under "Common phrases". The defaults are red, 25% opacity and a 45° angle, so you can press "Add watermark and save PDF" straight away.

Can I use my company logo as a watermark?

Yes. Choose "Image or logo" and add a PNG or JPG. A PNG with a transparent background looks best, and the image is kept in this browser for next time.

Can the watermark repeat across the whole page?

Yes. Choose "Repeat across the page" under "Layout" and adjust how close the copies are with "Space between repeats".

Can I leave the first page without a watermark?

Choose "Choose pages" under "Apply to" and type 2- in "Page range" to cover page 2 to the end. You can also choose only odd or only even pages.
