FAQ

How do I add a watermark to a PDF online?

Upload your PDF, choose a text watermark or image watermark, adjust opacity, angle, size, and layout, then export the new file directly in your browser.

Can I add a logo watermark to a PDF?

Yes. You can upload a JPG or PNG logo and place it on the PDF as an image watermark, which is useful for branded reports, proposals, and client documents.

Will a watermark cover the original PDF content?

Not if you tune it correctly. Lower opacity and flexible positioning make it easy to protect the file without making the document hard to read.

Is this useful for confidential or internal documents?

Absolutely. Many people add watermarks like Confidential, Draft, Internal Use Only, or company names to control sharing and discourage misuse.

Is it safe to watermark PDFs online?

Yes. The watermarking process runs locally in your browser, so your PDF does not need to be stored on a remote server.
