Short answer: Open the document, place your signature where it's needed, and save or share the signed copy — all on your phone, with no printing or scanning. You can add a date, initials, a stamp or a watermark the same way before you send it back.
The print-sign-scan loop, gone
The old way to sign a PDF was absurd: print it, sign with a pen, scan it back, hope it's straight, then email it. An electronic signature replaces all of that with a few taps on the document you already have on your phone. For everyday business paperwork — approvals, agreements, acknowledgements — that's minutes saved on every document.
Step 1 — Open the document
Open the PDF or captured document you need to sign. If it's a paper original, photograph it first — clean edge detection gives you a tidy document to sign on. See capture.
Step 2 — Place your signature
Draw or apply your saved signature and drop it where it belongs. Add the date or your initials if the document needs them. Because your signature is saved, the next document takes seconds. More on e-signatures.
Step 3 — Add a stamp or watermark (optional)
Mark a document approved, paid or confidential with a saved stamp or watermark before it leaves your hands. It's a small touch that makes business documents look finished and clear about their status.
Step 4 — Save and share the signed copy
Save the signed document to your workspace and share it as a PDF or link over WhatsApp or email. The signed copy is filed alongside your other records, searchable and backed up, instead of living in your downloads folder. See sharing & export.
A note on what e-signatures are for
Electronic signatures are ideal for the high-volume, everyday paperwork that keeps a business moving — internal approvals, acknowledgements, routine agreements. For documents with specific legal formalities, check what your jurisdiction requires. Either way, the signed records stay encrypted and private to you; see security.
