Stamp PDF (Free, Private, No Upload)
Stamping PDFs with official marks, approval indicators, or date/time stamps is essential for document workflow management, approval tracking, and creating audit trails in business processes. Legal departments marking documents as "APPROVED" or "CONFIDENTIAL," administrative staff time-stamping received documents, quality control teams indicating inspection status, or anyone managing document workflows needs reliable stamping. This tool adds customizable stamps directly in your browser—text stamps with custom messages, date stamps showing processing times, or status indicators like "DRAFT," "FINAL," or "VOID." Unlike watermarks which are typically subtle background text for ownership, stamps are prominent foreground marks indicating document status or approval. Perfect for marking contracts as executed, indicating review status on proposals, time-stamping incoming correspondence for records management, or adding official seals to certificates. Position stamps precisely where needed, choose from preset formats or create custom text, and apply to specific pages or entire documents. The browser-based processing keeps sensitive legal documents, financial records, or confidential business files completely private on your device without server uploads.

FAQ
How are stamps different from watermarks?
Stamps are prominent foreground marks indicating status (like "APPROVED" or dates), while watermarks are typically subtle background text for ownership or branding. Stamps are meant to be obvious and attention-grabbing; watermarks are more subtle.
Can I create custom stamp text?
Yes, enter any custom text for your stamp, from status indicators ("CONFIDENTIAL," "DRAFT") to approval marks ("Reviewed by [Name]") or dates. Customize font size, position, and opacity to match your document management needs.
Can stamps include dates and times?
Yes, add dynamic date and time stamps showing when the document was processed. This is crucial for audit trails, records management, and proving when documents were received, reviewed, or approved in business workflows.
Will stamps cover document content?
Stamps are placed on top of existing content. Choose positioning carefully to mark documents clearly without obscuring important text. Adjust opacity if you need stamps visible but not overwhelming, or use solid stamps for maximum visibility.
Are files uploaded?
No, all stamping happens in your browser using JavaScript. Your legal documents, financial records, or confidential business files never leave your device, maintaining complete privacy for sensitive materials requiring workflow tracking.
