How to Add a Watermark to a PDF Online for Free
Adding a watermark to a PDF helps protect your documents by marking them as confidential, draft, or proprietary. Watermarks are semi-transparent text or images overlaid on each page, discouraging unauthorised use while keeping the content readable. Our free online tool lets you add custom text watermarks with control over font size, colour, opacity, and rotation. Process your documents entirely in your browser for complete privacy and security.
Frequently Asked Questions
Can I customise the watermark text and appearance?
Yes. You can set custom text, adjust the font size, choose the colour and opacity, and control the rotation angle. This lets you create anything from subtle background marks to prominent overlay text.
Will the watermark cover the document content?
Watermarks are semi-transparent by design so the underlying text and images remain readable. You can adjust the opacity to find the right balance between visibility of the watermark and readability of the content.
Can I remove a watermark after adding it?
The watermark is permanently applied to the downloaded PDF. Keep your original un-watermarked file if you may need a clean version later. You can always re-process the original with different watermark settings.
