Why sign electronically
Printing a document, signing it and scanning it back takes time and a printer, and the scan is often crooked, grey and large. Signing the PDF directly gives a clean page with a clear signature, ready to email or upload in a minute.
Steps
- Open Sign PDF and choose the document. It stays on your device; nothing is uploaded.
- Create your signature: draw it with a finger, mouse or stylus, type your name, or use a photo of your signature on white paper.
- Place it on the page and drag its corners to the right size. Turn on the date option if the form asks for the date next to the signature.
- Download the signed PDF and open it once to check every signature is where it should be.
Tips for a signature that looks right
- If you use a photo, sign with a dark pen on plain white paper and photograph it in daylight, without shadows.
- Drawing works best on a phone with a finger, or a laptop with a stylus; a mouse gives shaky lines.
- Keep the signature about as large as it would be on paper, so it fits the line or box on the form.
- Sign every page that needs it; many agreements ask for a signature or initials on each page.
Electronic signatures and the law
For everyday forms, applications, letters and many agreements, an image of your signature on the PDF is widely accepted. Some documents need a certified digital signature (in India, a DSC or Aadhaar eSign), for example certain government filings, tenders and company documents. If a form says it needs a digital signature certificate, an image of your signature isn't enough; check what the organisation asks for.
