All stamps
FOR REFERENCE ONLY stamp for PDF
Mark drawings and documents that must not be used for the real work.
Which stamp for which step
Most office documents move through the same steps. Each step has its own stamp, and the stamps are not interchangeable:
- Before the document is final: use DRAFT while a document is under review, and remove it from the final version.
- When a document arrives: use RECEIVED to record arrival. It does not mean that you agree with the content.
- When a person signs off: use APPROVED after the person with authority has checked the document.
- When money is cleared: use PAID for one payment, or PAID IN FULL when the last part payment clears the balance.
- When you share a duplicate: use COPY so the duplicate is not paid twice or treated as the original.
- When the reader must not rely on it: use FOR REFERENCE ONLY on superseded or uncontrolled versions.
- When the content is private: use CONFIDENTIAL to tell the reader not to pass it on.
How to use a stamp from the library
- Open the page for the stamp and download the PNG.
- Open the Stamp & Sign tool and choose your PDF.
- Select Use your own image on this device and pick the PNG. The red, blue, and black PAID stamps are built into the editor, so you can skip the download for those.
- Tap the page to place the stamp. Drag it, and resize it with the corner handle or the Stamp width slider.
- Choose Download stamped PDF.
One stamp or every page
A stamp marks one spot on one page. That is correct for an invoice total, a signature block, or a title block. For a mark across every page of a long document, such as DRAFT or CONFIDENTIAL, use the watermark tool. See How to stamp all pages of a PDF for the two methods.
What a stamp does not do
Each stamp is a visual label. It does not prove payment, identify the person who placed it, or protect the file. Keep the unstamped original, and keep your normal records for approvals and payments.
