How to sign PDF files online

You don’t need to have paper, pens, printers and scanners to sign a document. You can  easily use Lumin PDF to sign all the necessary documents quickly online. There are two ways to insert your signature on a  PDF: using an electronic signature or a digital signature. 

An electronic signature is a signature image that you create by yourself or use a scan from an existing document. An electronic signature is suitable for those types of documents for which you don’t need a high level of security:

  • Signing presentations, books, and copyright materials
  • Sign a non-disclosure agreement for employment
  • For printed materials — business cards, booklets, catalogs, etc.
  • Email signatures

Digital signatures are an advanced and secure form of verification from the sender. Before adding your digital signature, you will be prompted for a PIN to prove your identity. Document and signature are encrypted and bound with electronic proof seal. Digital signatures are commonly used for software distribution, financial transactions, contracts and other cases where it is important to detect forgery and tampering.

 You can create a signature by yourself. Adding a signature to a PDF document is almost like on paper. 

  1. Click the Signature icon on the Lumin toolbar
  2. Click Create Signature
  3. Draw paint the signature with a brush, as in any graphics editor
  4. Drag, resize and position the signature inside your PDF file
