How do I put a password in a pdf file?

Hello Jorgefu,

You can limit access to a PDF by setting passwords and by restricting certain features, such as printing and editing. However, you cannot prevent saving copies of a PDF. The copies have the same restrictions as the original PDF.

You can password protect a PDF using Acrobat Pro DC, however, with freeware Adobe Reader, you cannot protect a PDF with password as Adobe Reader is used for viewing, printing, signing, and annotating PDFs.

To know more about securing a PDF with password, you can refer to Adobe article Securing PDFS with passwords, Adobe Acrobat

For plan and pricing of Adobe Acrobat, refer to Plans and pricing | Adobe Acrobat DC

To know more about Adobe Reader, refer to Answers to some of the most frequently asked questions about Adobe Acrobat Reader DC.

Feel free to update this discussion for any further assistance.

Thanks,

Anand Sri.
