Frequently Asked Questions
Everything you need to know about using our PDF stamp and signature tool.
How do I add a stamp to a PDF?
Upload your PDF, upload a stamp or signature image (preferably a transparent PNG), then click anywhere on the page to place it. Our AI-assisted PDF stamp tool converts your click into precise PDF coordinates so the stamp appears exactly where you expect.
Is my PDF secure?
Yes. All PDF files and stamp images are transferred over HTTPS and are automatically deleted shortly after processing. We never use your PDFs for training and we do not store your documents longer than necessary to generate the stamped PDF.
Can I use my own company stamp or seal?
Absolutely. You can upload any company stamp, seal, or logo as a PNG, JPG, or SVG file. For best results, we recommend a high‑resolution transparent PNG so your digital stamp blends cleanly with the PDF background.
Does your PDF stamp tool support multiple pages?
Yes. You can place stamps and signatures on any page of a multi‑page PDF. Use the page controls to jump between pages, click to place the stamp, and our tool will remember the exact position for each page you choose.
