Watermark PDF FAQs

  • What can I use as a watermark?

    You can add any text to protect or brand your PDF. Labels like “Confidential,” “Draft,” your name, or your company name are popular. But the choice is up to you.

  • Can I add image watermarks?

    This tool supports text watermarks only. To add logos, graphics, or image watermarks, use our Edit PDF tool, which lets you insert images of any type onto your PDF pages.

  • Will the watermark appear on every page?

    Yes, the watermark applies to all pages in your PDF automatically. This ensures consistent protection or branding throughout your entire document.

  • Is my document secure during the watermarking process?

    Absolutely. We use TLS encryption for all file uploads and downloads. We also automatically delete all files from our servers after one hour of processing, unless you choose to create an account and save your files on our secure servers.
