Watermarks are used to mark documents with their status or confidentiality level. A CONFIDENTIAL watermark on a PDF immediately signals to the reader how the document should be handled. A DRAFT watermark prevents a document from being mistaken for a final version.

When to Use a PDF Watermark

Marking contracts and legal documents as CONFIDENTIAL before sending
Stamping reports or proposals as DRAFT during review cycles
Adding a DO NOT COPY or SAMPLE watermark to protect your work
Branding documents with your company name before sharing
Marking sensitive HR or financial documents before distribution

Is the Watermark Permanent?

Yes. The watermark is embedded into the PDF as a permanent visual element — it is not a metadata tag. It is visible on screen and in print, and cannot be removed without specialist PDF editing software. This makes watermarked PDFs appropriate for controlling distribution of sensitive documents.

Is It Safe to Upload My PDF?

All files uploaded to PDFMadeSimple are transferred over SSL encrypted connections. Your PDF is permanently deleted from our servers within 24 hours. We are fully GDPR compliant and never share your files.
