Solution 1Recommended

Upload the File Using a Different Web Browser

Switching to a different web browser helps bypass browser-specific caching issues or stuck background tasks that trigger the error.

Often, a stalled background process in your current browser will lock the cloud conversion tool. Accessing the service from a fresh environment clears this state.

1
Open an alternative browser

Launch a different web browser than the one you are currently using, such as Google Chrome, Mozilla Firefox, or Safari.

2
Log into Document Cloud

Navigate to the Adobe Document Cloud website (cloud.acrobat.com) and log in with your credentials.

3
Retry the upload

Select the Word document and attempt to upload and convert it to PDF again.

Frequently Asked Questions

Why does Document Cloud say another operation is in progress?

This error typically occurs if a previous file upload was interrupted, a background task got stuck, or browser cache data is conflicting with the current session.

How can I cancel a stuck upload in Document Cloud?

You can clear a stuck upload by refreshing the page, logging out and back into your account, clearing your browser cache, or simply switching to a different web browser.

Is there a way to convert Word to PDF without uploading it to a cloud service?

Yes. You can use desktop software like WPS Office or Adobe Acrobat to natively export and save your Word documents directly as PDF files on your computer's local drive without needing an internet connection.
