There are several ways to sign a PDF, including:
- Using Adobe Acrobat Pro: This is a paid program that allows you to add a digital signature to a PDF. You can also use Adobe Sign, a cloud-based service for creating, sending, and tracking signatures.
- Online PDF Signing services: There are several online services available, such as DocuSign, Adobe Sign, or HelloSign, which allow you to upload a PDF and add a digital signature.
- Using a mobile app: There are several mobile apps available for both iOS and Android devices that allow you to sign a PDF on the go.
- Using a scanner or printer: If you have a scanner or printer with built-in PDF scanning or printing capabilities, you can print the PDF and sign it manually, then scan it back and save it as a PDF.
- Using a Graphics software: You can open the PDF in a graphics software such as Adobe Photoshop or GIMP and add an image of your signature then save the PDF.
When you sign a PDF digitally, you can use a digital certificate to prove your identity and ensure that the document cannot be tampered with after it is signed.
