A watermark can identify a working copy as DRAFT or REVIEW COPY. The aim is to make the label noticeable while keeping the document readable. A visible watermark is a label, not a way to encrypt a file or prevent copying.
Step-by-step instructions
- Choose a short label using English letters, numbers or punctuation.
- Select the source PDF in Watermark PDF.
- Enter the wording, staying within the 80-character limit.
- Prepare and download the marked copy.
- Check pages with photographs, dark backgrounds and dense text, where the same label can look different.
A practical example
Use REVIEW COPY for a document being checked before release. Keep the wording concise rather than adding a long sentence across every page. Save the download with a clear filename so a reviewer does not confuse it with the final version.
Common mistakes and limits
The current watermark has a fixed light appearance and diagonal angle. It is applied to every page. It does not support logo images, non-ASCII scripts, custom opacity or a selected page range. A watermark may be difficult to see over a busy photograph.
Frequently asked question
Can a watermark protect confidential details?
No. Underlying words and images remain in the PDF. Do not rely on a label to stop an authorised viewer from copying information. Remove sensitive information through an appropriate redaction process before distributing a document.
