How to Replace a Shared PDF in Acrobat Without Losing Comments
Question details
The user needs to upload a revised version of a PDF document without generating a new link and losing existing reviewer comments.

- Product
- Adobe Acrobat Document Cloud
- Device & OS
- not provided
- Scenario
- Uploading a revised PDF file to Document Cloud to update a previously shared document.
- Observed behavior
- Uploading a file with the same filename creates a new shared link instead of prompting to replace the existing file and preserving its comments.
Ensure you are signed into the exact same Adobe account that was used to share the original PDF file, as using a different ID will prevent you from overwriting existing files.
Upload the Revised PDF via Document Cloud Web Interface
Manually uploading the updated file through the Adobe Document Cloud web interface often correctly triggers the file replacement prompt.
Uploading directly through the web portal bypasses potential desktop application syncing glitches and forces the system to recognize duplicate filenames.
Open your web browser and navigate to the Adobe Document Cloud website (documentcloud.adobe.com), then sign in with your Adobe ID.
Click the 'Upload' button and select the revised PDF file from your computer. Verify that the file has the exact same name as the originally shared PDF.
When the system prompts that a file with this name already exists, choose the option to 'Replace existing file'. The new file will overwrite the old one while preserving the existing shared link and comments.

Troubleshoot File-Specific Sync Issues
Test the replacement process with a fresh document to determine if the issue is isolated to a corrupted PDF or a broader account problem.
Collaborate on PDFs Seamlessly with WPS Office
Avoid complex syncing and replacement issues by using WPS Office for your PDF collaboration. WPS Office offers an integrated cloud workspace where you can easily share PDFs, collect feedback, and update document versions natively without losing reviewer comments.

- 2. Upload to WPS Cloud: Click on 'Share' or 'Save to Cloud' in the top right corner to upload the document to your secure WPS Cloud workspace.
- 3. Generate a collaborative link: Create a sharing link with the appropriate editing or commenting permissions and distribute it to your team.

Frequently Asked Questions
Why doesn't Acrobat prompt me to replace the existing shared file?
This typically happens if you are logged into a different Adobe account, the file name does not match the original exactly, or the original file's sharing permissions have expired or been revoked.
Can I recover comments if a new shared link was accidentally created?
If a new link was generated, the comments remain tied to the original file's link. You cannot automatically merge comments from the old link to the new link; you must successfully replace the original file using its exact name to keep the comments intact.
Does replacing a PDF in Document Cloud notify my reviewers?
Yes, reviewers who have been invited to the shared PDF will typically see the updated version automatically when they next open the link, and any preserved comments will remain visible on the new document version.
