Frequently asked questions
Is this legally binding everywhere?
Laws vary by country and document type. For critical contracts, use a compliant e-signature service.
Do you store my signature?
No. Signature data stays in the browser session for this tool.
Can I sign every page at once?
Yes. Choose “Same position on all pages”, place once, then sign. Or use “This page only” for a single page, or “Position each page” to place separately.
Does signing reduce PDF quality?
No. Pages are kept as original PDF content; only a signature image is added on top.
