About this tool

Add Stamps places a classic double-bordered rubber stamp on your pages. Choose a preset — APPROVED, DRAFT, CONFIDENTIAL, FINAL, PAID, REJECTED, COPY, RECEIVED, the Thai “อนุมัติแล้ว” and “สำเนาถูกต้อง”, a date stamp — or type your own wording.

Add today's date under the main text, pick a position, angle, size and opacity, and stamp only the first page or any range. Each preset has a fitting colour, or choose your own.

Stamps are vector shapes and text, so they look crisp at any zoom and print cleanly. Processed privately in your browser.
