How can I have someone sign on a PDF file?

When you need to get documents signed, send them to the recipient from airSlate SignNow. Upload a PDF/DOCX/image to the service, add fillable fields for text and signatures, and use the Invite to Sign function. Your recipient doesn't need to have an account. They will receive an email notification and get access to the file. When the signer finishes signing the PDFs, you both get signed copies of the document. If you want to raise the security level, on the step of indicating recipients, click Advanced options, add additional authentication: a password, phone call, or SMS. When you get the signed PDF, export the file with History.
