How to Stamp PDF Document
Stamping a PDF adds a visible overlay — like 'APPROVED,' 'CONFIDENTIAL,' 'DRAFT,' a date stamp, or a custom logo — across one or all pages of your document. Stamps communicate document status at a glance and are standard practice in legal, government, and corporate workflows. SublimePDF lets you apply text stamps, image stamps, and dynamic stamps (with auto-populated dates and usernames) to any PDF.

Upload your PDF
Open SublimePDF's stamping tool and upload the document you want to stamp. Multi-page documents are supported — you can stamp all pages or select specific ones.
Choose a stamp type
Select from preset text stamps (APPROVED, DRAFT, CONFIDENTIAL, COPY, VOID), custom text (type anything), or image stamps (upload your company seal, signature image, or custom graphic).
Configure stamp appearance
Set the stamp color, opacity (transparent stamps let content show through), rotation angle (diagonal stamps are standard for status markers), font size, and border style.
Position the stamp
Place the stamp by clicking on the page, or choose automatic positioning (center, top-right, bottom-left, etc.). Drag to adjust and resize as needed.
Apply to selected pages
Choose to stamp all pages, only the first page, only the last page, odd pages, even pages, or a custom page range. Status stamps like 'DRAFT' typically go on every page.
Save the stamped PDF
Download the document with the stamp permanently embedded. The stamp becomes part of the page content and cannot be removed by the recipient.
Pro Tips
- 💡 Use 30–50% opacity for diagonal text stamps (DRAFT, CONFIDENTIAL) so the underlying content remains readable while the status is clearly visible.
- 💡 For official stamps (APPROVED, CERTIFIED), position them in the upper-right corner of the first page at full opacity — this is the standard placement in most corporate and legal workflows.
- 💡 Include the date in status stamps (e.g., 'APPROVED — Feb 24, 2026') to create a clear record of when the status was applied.
- 💡 If you need to apply the same stamp to multiple documents, use SublimePDF's batch stamping feature to process them all at once.
