Allow or block links to the Internet in PDFs
Clicking any link to the Internet poses a potential security risk. Malicious websites can transfer harmful content or
silently gather data. If you are concerned about these risks, you can configure Acrobat and Reader to display a warning
when a PDF attempts to connect to an Internet site.
You can allow Acrobat and Reader to contact selected websites by adding their addresses (URLs) to your list of trusted
websites in the Trust Manager preferences. Alternatively, you can allow all URLs.
Note: If the options in the Manage Internet Access dialog box are disabled, select Custom Setting. If options are still
disabled, your product could be under an administrator’s control with those restrictions in place.
1 Choose Edit > Preferences (Windows) or Acrobat/Adobe Reader > Preferences (Mac OS).
2 From the Categories on the left, select Trust Manager.
3 Click Change Settings to specify the default behavior for accessing the Internet from PDFs.
