How to Whitelist Ports and URLs for Adobe PDF Export

Product: Adobe Export PDF
Device & OS: not provided
Scenario: Exporting PDFs in a managed corporate or restricted network environment.

Before you start

Solution 1Recommended

Configure Firewall and Proxy Settings for Adobe Document Cloud

Whitelist the necessary Adobe service URLs and ports to allow Adobe Export PDF to communicate through your network's firewall.

Adobe Export PDF relies on Adobe Document Cloud services, which require specific HTTPS traffic to pass through your network unhindered. Blocking these endpoints will cause export failures.

Identify required ports

Ensure that port 443 (HTTPS) and port 80 (HTTP) are open for outbound traffic, as Adobe services rely on these standard web ports.

Whitelist Adobe domains

Add Adobe's core service domains (such as *.adobe.com, *.acrobat.com, and *.adobelogin.com) to your firewall or proxy's allowed list.

Bypass SSL inspection

If your network uses strict SSL inspection, configure an exception for Adobe Document Cloud URLs to prevent connection drops.

Verify security software

Check local antivirus or endpoint security software to ensure it is not blocking Adobe Acrobat or Adobe Reader from accessing the internet.

Configure Firewall and Proxy Settings for Adobe Document Cloud

Consult Adobe Documentation: For the most up-to-date and exhaustive list of specific endpoints, refer to the official Adobe Document Cloud connectivity requirements guide.

Frequently Asked Questions

Why does Adobe Export PDF require internet access?

Adobe Export PDF is a cloud-based service that processes the file conversion on Adobe's servers. Therefore, it requires a stable internet connection and unrestricted access to Adobe Document Cloud endpoints.

Can I export PDFs offline using Adobe Acrobat?

While the free Adobe Reader relies on the cloud-based Export PDF service, the paid desktop version of Adobe Acrobat Pro can perform conversions locally without an internet connection.

How do I know if my firewall is blocking Adobe services?

If your firewall is blocking access, you will typically see a connection error, a timeout message, or a prompt stating that Adobe Export PDF cannot connect to the internet when you attempt to convert a file.

What are the exact URLs I need to whitelist for Adobe?

You generally need to whitelist domains like *.adobe.com, *.acrobat.com, and *.adobelogin.com. For a complete and updated list of specific URLs and IP addresses, consult the official Adobe Enterprise administration guide.
