Stamp a PDF: APPROVED, CONFIDENTIAL, DRAFT or custom text
1 min read·25 July 2026
Adding an official stamp to a PDF, "APPROVED", "DRAFT", "CONFIDENTIAL" or custom text, gives documents an instant status indicator. PDFrust does it free in your browser.
When to use a stamp?
Stamps are useful for: documents that have been approved and need marking, draft versions that must not be confused with the final version, confidential documents that need a visual warning, invoices that have been paid ("PAID"), or expired quotes.
Difference between stamp and watermark
A watermark covers the entire page as a diagonal overlay, visible but transparent. A stamp is a small, rectangular element at a specific location (typically corner or centre). Both are useful; the choice depends on the desired visual emphasis.

Pre-set stamps
PDFrust offers ready-made stamps: APPROVED (green), REJECTED (red), DRAFT (orange), CONFIDENTIAL (red), PAID (green). Choose colour, size and position.
Custom text as stamp
Type your own stamp text, company name, project code, date, or free text. Combine with a border for a more professional look.
Permanently embed the stamp
After adding a stamp, use the flatten tool to permanently embed it in the PDF: so it can no longer be removed as a separate layer.
