How to how to sign a pdf without printing

  1. 1. Ask which kind of signature the recipient accepts.
  2. 2. Use a certificate flow when they require validation.
  3. 3. Keep the unsigned original separate from the signed copy.

Printing, signing, and scanning produces a picture of ink. It is common, and some recipients accept it. It is not a cryptographic signature. A cryptographic signature uses a certificate, can be validated, and can show whether the bytes changed afterward. Typing your name in a form field is a third thing. Pasting a PNG of your handwriting is closer to the scan than to the certificate.

This version does not apply any of those, because doing it badly would look like a signature. If you need a certificate, use a tool that shows the certificate’s name. If a portal accepts a scanned ink page, scan it locally. Do not upload the unsigned contract to a site that offers “sign in one click” unless you have decided they may hold it. The work this guide points to stays in the browser. No upload is required to follow it.

How to sign a PDF without printing stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
