- Adding a consistent signature image across a document you send often
- Approving a document quickly from a phone or tablet
Supported formats and limitations
Accepts PDF, up to one file at a time.
- This adds a visual signature image on top of the page — it is an electronic signature overlay, not a cryptographic digital certificate signature and not a qualified electronic signature under eIDAS or similar standards. It carries no built-in identity verification or tamper-evidence.
- One signature image can be placed on multiple pages, but each placement is added independently — there's no automatic "sign every page" batch action.
- One PDF at a time, up to 40 MB.
