How to protect pdf files with password?

Protect sensitive information with simple-to-use security features. Use PDF passwords, digital signatures, and redaction to build electronic processes you can trust.

Easily add a variety of electronic signatures to your PDF files

As more workflows go digital, people are using digital signatures to save time and money. With Adobe® Acrobat® X Pro software, you can easily add electronic signatures to a PDF file, including simple signature scans and verifiable digital signatures. Anyone can view your signed PDF files using free Adobe Reader® software.

APPLY A BASIC INK SIGNATURE TO A PDF FILE

Many documents require just a digital image of your signature. Using Acrobat, you can quickly sign documents electronically by creating and using a stamp with a digital scan of your signature. If you use a drawing tablet with a digital pen, you can also add a simple handwritten signature anywhere in a PDF file using the Apply Ink Signature tool.

CREATE YOUR OWN DIGITAL ID TO SELF-SIGN DOCUMENTS

To send and receive documents with confidence among trusted colleagues or business partners, Acrobat X lets you digitally sign documents with a free digital ID you create. Recipients can then validate your signature and easily determine if the document has been altered in any way since you signed it.

APPLY DIGITAL SIGNATURES VERIFIED BY THIRD PARTIES

Many business transactions, including financial and legal transactions, require formal verification of a document’s integrity and the identity of all signers. Acrobat X enables such verification through powerful encryption and public key infrastructure (PKI) support. Using Acrobat, you can sign and certify PDF files using a higher assurance digital signature verified by a trusted third-party certificate authority through the purchase of a digital ID. Recipients can then use Acrobat or free Adobe Reader software to validate the authenticity of signed documents with certificate authorities.

LET ANYONE SIGN YOUR PDF FILES USING FREE ADOBE READER

Anyone can use free Adobe Reader software to view PDF files, validate digital signatures, and verify document certification. Acrobat X Pro also lets you enable Reader users to digitally sign PDF documents and forms.
