Guide
Why watermark PDFs
Watermarking injects Form XObjects or artifact-marked content streams into the page paint order with explicit opacity — not a screenshot sticker.
DSNOOPDOC supports text and image watermarks with position, rotation, and transparency so DRAFT diagonals stay vector-crisp at any zoom.
Watermark before external distribution — not after recipients saved an unmarked copy.
Text and image stamps
CONFIDENTIAL typography or brand PNGs with alpha channels.
Opacity control
Balance underlying text legibility against stamp visibility.
Position and angle
Diagonal drafts or footer stamps on every sheet.
Not redaction
Hidden text layers may still exist — redact sensitive content before watermarking.

Security & privacy
What happens to your file
Your file is used once, then removed
Uploads are used to produce your watermarked download — they aren't kept afterward unless you save to a workspace.
No account required
Upload, configure your watermark, and download without creating an account.
Files aren't shared or indexed
What you upload stays private to your session — it isn't visible to other users or reused for anything else.
FAQ
Frequently asked questions
?Can recipients remove watermarks?
Casual viewers cannot easily remove embedded stamps; determined editors with PDF tools might. Watermarks deter misuse; they are not DRM.
?Image watermark formats?
PNG with transparency works best.
?Does watermarking increase size?
Modestly for text stamps; image stamps add the XObject bytes.
?Print visibility?
Opacity settings affect print the same as screen — test a proof page first.
?Watermark vs protect?
Watermarks are visual. Use protect-pdf to encrypt with a password.
?Flatten watermarks?
Export preserves interactive stamps until you flatten for archival.
Before you send it
Signed PDFs deserve accountability — track opens or publish as a completion form.
