Fix Acrobat Omitting JPEG Attachments When Converting Outlook Emails to PDF
Question details
Users need to know how to resolve an issue where Adobe Acrobat XI drops image attachments with a .jpeg extension during email-to-PDF conversion.
- Product
- Adobe Acrobat XI
- Device & OS
- not provided
- Scenario
- Archiving or converting Microsoft Outlook emails to PDF format.
- Observed behavior
- Acrobat XI successfully includes attachments with the .jpg extension but completely omits image attachments that use the four-letter .jpeg extension.
Verify the exact file extensions of your email attachments in Outlook and ensure your Acrobat application is closed before attempting to install any updates.
Rename the .jpeg File Extensions to .jpg
Since Acrobat XI processes .jpg files correctly but struggles with the .jpeg extension, manually renaming the attachments is the most effective workaround.
The issue stems from how the Acrobat XI add-in parses file extensions during the conversion process. Changing the extension circumvents this bug without altering the image data.
Open the email in Microsoft Outlook, right-click the .jpeg image attachment, and select 'Save As' to download it to your computer.
Navigate to the saved file in File Explorer, right-click it, select 'Rename', and change the '.jpeg' suffix to '.jpg'. Press 'Enter' to confirm the change.
Forward the email to yourself with the newly renamed .jpg file attached, and use the Acrobat add-in to convert it to PDF. The image will now be included.

Use WPS Office for Flawless PDF Conversions

- 1. Open your document: Launch WPS Office and open the document or image file you wish to convert.
- 2. Access PDF export: Click on the 'Menu' button in the top left corner and select 'Export to PDF'.
- 3. Export the file: Configure your preferred export settings and click the 'Export' button to generate a complete PDF.
Frequently Asked Questions
Why does Acrobat XI omit .jpeg attachments but not .jpg?
This is a known bug in Acrobat XI's Outlook add-in. The software's parser fails to recognize the four-letter '.jpeg' extension as a valid, supported image attachment during the PDF archiving process, whereas the standard '.jpg' extension is coded correctly.
Will disabling external attachment blocking fix this issue?
No. Disabling external-attachment blocking in your security settings will not resolve this problem, as the omission is caused by an extension-reading glitch in the PDF converter, not a security block.
Is there a way to print the email to PDF directly without the Acrobat add-in?
Yes. You can bypass the Acrobat add-in by opening the email in Outlook, pressing 'Ctrl + P', and selecting 'Microsoft Print to PDF' as your printer. This will convert the email and any visible inline images into a PDF document.
