Marking a document as "DRAFT," "CONFIDENTIAL," or "SAMPLE" across every page is a quick way to signal its status before it's finalized or shared widely. This tool stamps your chosen text onto every page of an uploaded PDF in a light, unobtrusive gray, without altering the original page content underneath.

It works on any number of pages, applying the same watermark text consistently throughout the document.

How it works

Upload a PDF and enter the watermark text you want stamped onto every page — like "DRAFT" or "CONFIDENTIAL." The tool overlays that text in a light gray tone across the center of each page, preserving the original content underneath, and gives you a new PDF to download.

  1. Upload a PDF file.
  2. Enter the watermark text (e.g. DRAFT).
  3. Generate and download the watermarked PDF.

Examples

Marking a document as a draft

Uploading a 10-page proposal and entering "DRAFT" as the watermark text stamps that word onto all 10 pages, making it clear at a glance that the document isn't final.

Marking a document confidential

Entering "CONFIDENTIAL" before sharing an internal report externally marks every page clearly, reducing the chance it gets mistaken for a public document.

Who should use it

  • Marking a document as a draft before it's finalized.
  • Marking a document confidential before sharing it externally.
  • Labeling a sample or preview version of a document distinctly from the final version.

Industry applications

  • Legal and contract management
  • Publishing and reporting
  • Business and office administration

Advantages

  • Watermarks every page consistently in one step.
  • Preserves the original page content and layout underneath.
  • Works on any number of pages in a single upload.

Limitations

  • Fixed horizontal center placement, not fully configurable positioning.
  • Light gray tone only, not a fully customizable color or opacity.
  • Can't open password-protected or corrupted PDFs.

Common mistakes to avoid

  • Assuming a text watermark provides real security or prevents copying — it's a visual marker, not a protection mechanism.
  • Using very long watermark text that may not fit cleanly across narrower pages.
  • Trying to watermark a password-protected PDF without removing the password first.

Best practices

  • Keep watermark text short and clear — single words or short phrases like "DRAFT" work best.
  • Use a watermark to communicate document status (draft, confidential, sample), not as a security control.
  • Keep the original, unwatermarked file for your own records in case you need it later.

Tips

  • Use short, all-caps watermark text (like "DRAFT" or "SAMPLE") for the clearest, most conventional look.
  • Keep the original unwatermarked file on hand, since the watermark isn't reversible once applied to the downloaded copy.

Frequently asked questions

Yes, with no signup and no limit on how many files you watermark.
No — it's rendered in a light gray tone that sits visibly on the page without obscuring the text underneath.
Not yet — the watermark is placed horizontally across the center of each page, which suits most "DRAFT"/"CONFIDENTIAL"-style use cases.
Every page in the document gets the same watermark text applied.
The tool tells you directly that the file couldn't be read as a valid PDF, rather than producing a broken result.
It's used only to produce the watermarked PDF and isn't retained afterward — only the resulting output is kept, linked to your browser session so you can re-download it.
