Fix Acrobat XI Crashing When Converting Multiple EPS Files to PDF
Question details
The user needs to resolve an issue where the application stops and displays an error when attempting to merge a large batch of EPS files into a single PDF document.

- Product
- Adobe Acrobat XI
- Device & OS
- macOS 10.14.5
- Scenario
- Converting and combining a large batch of approximately 120 EPS files into one PDF.
- Observed behavior
- The conversion process stops prematurely with an error after successfully processing only a fraction (about 30) of the files.
Ensure your Mac has sufficient available RAM and disk space for heavy batch processing, and verify that the remaining EPS files are not corrupted by opening them individually.
Upgrade to a Supported Version of Adobe Acrobat
Acrobat XI is obsolete and prone to compatibility issues on modern operating systems; upgrading resolves core instability.
Adobe ended support for Acrobat XI in 2017. Running obsolete software on newer macOS versions (like 10.14 Mojave) often causes unexpected memory allocation errors during intensive batch processes.
Open Acrobat XI, click on 'Acrobat' in the top menu bar, and select 'About Acrobat' to confirm your version details.
Visit the official Adobe website, log into your Creative Cloud account, and download the latest version of Acrobat Pro or Standard.
Use the Acrobat uninstaller tool in your Applications/Utilities folder to completely remove Acrobat XI before installing the new version.
Open the newly installed Acrobat, navigate to 'Tools' > 'Combine Files', add your 120 EPS files, and click 'Combine' to create the PDF.

Identify and Isolate Problematic EPS Files
A single corrupted or overly complex EPS file can interrupt the entire batch conversion process.
Effortlessly Combine PDFs with WPS Office
While specialized tools handle raw EPS conversions, WPS Office provides a lightweight and powerful solution for combining converted images or individual PDFs into a single, polished document without crashing.
- 1. Convert EPS to PDF First: Use your system's built-in tools (like macOS Preview) to quickly export your EPS files as individual PDFs or high-quality images.
- 2. Open PDF Merge Tool: Launch WPS Office, go to the 'Tools' tab, and click on 'Merge PDF' under the PDF editing section.
- 3. Add Your Files: Click 'Add Files' and select all your newly converted PDFs or images from your storage folder.
- 4. Combine and Save: Arrange the pages in your desired order and click 'Merge'. WPS Office will quickly compile them into a single PDF document.

Frequently Asked Questions
Why does Acrobat XI crash when processing large batches of EPS files?
Acrobat XI is an older, unsupported application that struggles with memory management on modern macOS versions. Large batches overwhelm its available memory limit, causing unexpected application closures.
Can I combine PDF files without upgrading to Acrobat DC?
Yes, once your files are individually converted to PDF, you can use built-in macOS tools like Preview, or lightweight alternatives like WPS Office, to easily merge multiple PDFs into one document.
How do I know if an EPS file is corrupted?
Try opening the EPS file in macOS Preview or Adobe Illustrator. If the file fails to open, displays formatting errors, or crashes the viewer, it is likely corrupted and needs to be re-exported from the source software.
Does macOS natively support EPS files?
Older macOS versions (like macOS Mojave) natively supported viewing and converting EPS files in the Preview app. However, Apple deprecated EPS support in newer operating systems such as macOS Sonoma.
