Method 1 — Text Stamp via Watermark Tool

Go to pdfeditor.onl/watermark-pdf. Upload your PDF. Type your stamp text (APPROVED, PAID, RECEIVED, etc.). Set rotation to 0° for a clean horizontal stamp. Set opacity to 60–80% for a clearly visible stamp. Choose red for urgency, green for approval, blue for information.

Tip: Set a border around the stamp text in the settings for a more official stamp appearance.
