Solution 1Recommended

Remove and Reinstall the Acrobat Chrome Extension

Uninstalling the current potentially corrupted or outdated extension and installing a fresh copy from the Chrome Web Store usually resolves performance lags caused by update mismatches.

Updating Google Chrome does not guarantee that all installed extensions are updated simultaneously. A mismatch between the browser version and the Acrobat extension can result in slow processing when executing complex tasks like appending emails.

1
Open Chrome Extensions

Launch Google Chrome, click the three-dot menu icon in the top right corner, hover over 'Extensions', and select 'Manage Extensions'.

2
Remove the Outdated Extension

Locate the Adobe Acrobat extension in the list and click the 'Remove' button. Confirm the action to completely uninstall it from your browser.

3
Reinstall from the Web Store

Visit the official Chrome Web Store, search for 'Adobe Acrobat', and click 'Add to Chrome' to install the latest version.

4
Enable and Restart

Once added, make sure the extension is toggled on. Restart your Google Chrome browser and try appending an email to a PDF to verify the speed has normalized.

Remove and Reinstall the Acrobat Chrome Extension
Clean Installation: A clean installation effectively clears old cached data from the extension, which is the most common culprit for slow PDF conversions in the browser.

Frequently Asked Questions

Why did the Acrobat extension suddenly become slow after working fine?

Browser extensions can suddenly slow down due to background updates. If Chrome updates its core engine but the Acrobat extension hasn't received a corresponding patch, the compatibility gap causes performance lag, especially during file conversions.

How do I force an update for my Chrome extensions without reinstalling?

Navigate to chrome://extensions/ in your browser, toggle on 'Developer mode' in the top right corner, and click the 'Update' button that appears. This forces Chrome to check for and install updates for all extensions immediately.

Is there a way to append emails to a PDF without using any browser extensions?

Yes. You can open the email, press Ctrl+P (or Cmd+P on Mac), and choose 'Save as PDF' as the destination. Once the email is saved as a PDF locally on your computer, you can use a desktop PDF editor like WPS PDF to merge it with your existing file.
