What is a PDF watermark used for?
A PDF watermark marks every page with text or a logo to show that a document is a draft, confidential or yours. Add the word DRAFT, a company name or a logo to every page, or only to odd, even or selected pages.
How do I add a watermark to a PDF?
To add a watermark to a PDF, type your text or choose an image, then set its position, opacity and rotation in the live preview. For text, choose the font, size, bold, italic, underline and colour. The default is 30 percent opacity at 45 degrees, which is readable without hiding the page. Place it in one of nine positions or tile it across the page, over the content or behind it so text stays crisp.
Can I watermark personalised copies at once?
Yes, enter one line of text per version, for example a recipient name on each line, and you get a ZIP with one PDF per line.
Can a watermark be removed?
A watermark deters casual copying, but someone determined can remove it, because it is part of the page content. For access control, add a password with Protect PDF. For running text such as a title or date, use Header & footer. Everything runs on your device.
Frequently asked questions
Can I add a watermark to a PDF for free?
Yes. Watermark runs in your browser, so your files are not uploaded and there is no daily limit. Free files can be up to 200 MB each, with up to 50 files per task; Premium raises the limits.
What is a watermark in a PDF?
A watermark is text or an image, such as CONFIDENTIAL or a logo, placed on the pages of a PDF, often faint and at an angle. It shows the status or owner of a document.
How do I add a logo watermark to a PDF?
Choose image, upload your logo as a PNG or JPG, then set its size, position and opacity in the live preview.
Can I put the watermark behind the text?
Yes. Choose behind content so the page stays easy to read.
Can you remove a watermark from a PDF?
Not with PDFDaily: there is no watermark remover. A watermark is added as page content, which someone with the right tools can edit out, so it deters copying but does not lock the file.
Can I make a different version for each line of text?
Yes. Enter one version per line and you get a ZIP with one watermarked PDF for each.
