- Product
- Third-party PDF applications or services
- Device & OS
- not provided
- Scenario
- Publishing or generating a PDF document using an external application or cloud service like PDFSF Cloud.
- Observed behavior
- The progress bar or publishing status freezes at 40 percent and fails to complete the document processing.
Determine exactly which application or cloud service is actively handling your PDF publishing process, as the fix largely depends on the specific software provider you are using.
Verify the Application and Contact the Manufacturer
Since this specific freezing issue typically occurs with third-party products rather than native Document Cloud tools, reaching out to the specific software's support team is essential.
Adobe Support generally cannot troubleshoot or control external services. If your publishing process hangs when integrated with third-party plugins or platforms, the issue usually lies within the external server or application code.
Check the title bar or the progress window of the stalled process to verify if you are using a third-party application like PDFSF Cloud.
Note down the version number and the exact name of the third-party PDF publishing service you are attempting to use.
Visit the official website of the third-party manufacturer and submit a support ticket detailing that the process halts at exactly 40 percent.

Restart the Service and Check Network Connection
If you are using a cloud-based PDF publisher, a temporary network glitch or cached data might cause the process to hang midway.

Frequently Asked Questions
Why does my PDF conversion stop at exactly 40 percent?
This is typically a specific stall point tied to third-party cloud services or plugins. It often indicates a server timeout, a failure to render a complex element in the document, or an issue communicating with external APIs.
Can standard support fix third-party PDF publishing issues?
No, primary platform providers like Adobe cannot troubleshoot or control external services. You must contact the manufacturer of the specific third-party application you are using.
How can I prevent my PDF publishing process from hanging in the future?
Ensure your original document does not contain unusually large images or corrupted fonts. If you are using an unstable cloud service, consider switching to a reliable offline desktop application like WPS Office to generate your PDFs natively.
