Use cases

Confidential review packets

Add confidential watermark to PDF board materials — confidential watermark PDF visible on every page during circulation.

Draft document control

Apply draft watermark PDF to proposals so recipients know the version is not approved for execution.

Copyright protection

Add copyright notice to PDF ebooks and whitepapers — copyright watermark PDF deters casual redistribution.

Internal company branding

Stamp company name watermark PDF on internal memos — text overlay on PDF without desktop software.

Problems we solve

Cloud tools expose sensitive labels

Uploading a confidential draft to a remote server defeats the purpose. Local pdf text watermark keeps bytes on-device.

Inconsistent text placement

Manual Acrobat stamps vary page to page. Grid placement applies uniform text overlay on PDF across the full document.

Unreadable heavy overlays

Opaque stamps block content. Adjustable opacity keeps custom text watermark PDF readable underneath.

Trust & privacy

Preset and custom labels

Confidential watermark PDF, draft watermark PDF, copyright watermark PDF — or any custom string you type.

100% on-device

Add text watermark to PDF while bytes stay in your browser — zero server contact.

Free standard text stamps

Everyday company name watermark PDF jobs cost nothing. Premium handles batch and 100MB+ files.
