PASSWORD PROTECT A PDF

Drag and drop a PDF, then add a password to protect your file.
Select a PDF file to add a password.
Select a PDF file to add a password.

Your file will be uploaded to Adobe cloud storage. By using this service, you
agree to the Adobe Terms of Use and Privacy Policy.




PASSWORD PROTECT PDF FILES

Add PDF password protection with the Adobe Acrobat online tool. It means a
password is always needed to view the contents of your PDF file. 




RESTRICT UNAUTHORIZED ACCESS

When you password protect a PDF, you control file access. We’ll let you know if
your password is weak, medium, or strong.




PDF PASSWORD SECURITY YOU CAN TRUST

As the inventor of the PDF file format, Adobe delivers trusted document
security. Password protect your PDF with confidence from any browser on Mac or
Windows.


HOW TO PASSWORD PROTECT A PDF


HOW TO PASSWORD PROTECT A PDF

Follow these easy steps to create a PDF password:

Click the Select a file button above or drag and drop a PDF into the drop zone.

Enter a password, then retype it to confirm the password.

Click Set password.

Download the password protected PDF document, or sign in to share it.


QUESTIONS? WE HAVE ANSWERS.


HOW DO I CHOOSE A STRONG PASSWORD?

To create a strong password, increase the length of the password and add a mix
of letters (both upper and lower case) and numbers. The addition of symbols can
also increase password strength. When you enter passwords, avoid using personal
information or common words found in a dictionary that can be guessed more
easily.


HOW DO I UNLOCK A PASSWORD-PROTECTED PDF?

When you open a PDF protected by a password, you’ll be prompted to enter the
password. Type it in and click OK. Then the file will open.


WHAT IS THE DIFFERENCE BETWEEN PASSWORD PROTECTION AND ENCRYPTION?

When you protect documents with a password, people who enter the correct
password can access the file or folder. A stronger security method is
encryption, with common types being 128-bit key or 256-bit AES encryption.
Encryption turns document content into unreadable cipher text. To decrypt the
document, authorized users need a key, which is typically a password or a
digital certificate.

 

When you use the Acrobat online tool to add password protection to a PDF file,
it encrypts the file for added security. If you need more advanced PDF security,
you can try Adobe Acrobat Pro for free for seven days to add encryption options,
encrypt with certificates, or manage security settings and permissions to
restrict editing, printing, or copying. Acrobat Pro also lets you edit PDFs,
organize PDF pages, and convert PDFs to and from Microsoft Office 365 files,
including Microsoft Word documents, PowerPoint presentations, and Excel
spreadsheets.

 * What are cookies and why does Adobe use them?
   
   Cookies are small text files stored by your web browser when you use
   websites. There are also other technologies that can be used for similar
   purposes like HTML5 Local Storage and local shared objects, web beacons, and
   embedded scripts. These technologies help us do things like remembering you

   technologies you want us to use on Adobe sites when you visit them from this
   browser. You can always change those choices later by clicking on the Cookie
   Preferences link at the bottom of the page.




IF ENABLED:

 * We can improve your experience by tailoring the site and the content to
   things we think might be of interest
 * We can better keep track of your preferences — like what language you prefer
   to use
 * We will better understand your likely interests so we can provide you more
   relevant Adobe ads and content on non-Adobe websites and in non-Adobe apps
 * It will help us improve the performance of our website and those of our
   partners who use the Adobe Experience Cloud


IF DISABLED:

 * We won’t be able to remember you from session to session so the experience
   may not be tailored to your interests
 * You’ll still have access to the content of the site but certain features that
   depend on cookies may not function
 * You’ll still see ads, they just may not be as relevant to you
