How to Compare PDF Files in Acrobat Pro for iOS
Question details
The user is looking for a way to compare two PDF files to find differences using the Adobe Acrobat Pro app on an iOS device.
- Product
- Adobe Acrobat Pro
- Device & OS
- iOS
- Scenario
- Attempting to track changes or identify differences between two versions of a PDF document while working from a mobile device like an iPhone or iPad.
- Observed behavior
- The file comparison tool is completely missing from the Tools menu in the iOS app, and purchasing the AI add-on does not unlock this functionality on mobile.
Since PDF comparison requires desktop-level capabilities in Adobe Acrobat, ensure you have access to a Windows or Mac computer to perform this task.
Use the Desktop Version of Adobe Acrobat Pro
Because the iOS mobile app does not support file comparison, you must transfer your documents to a computer and use the desktop version of Adobe Acrobat.
Currently, Acrobat Pro for iOS limits certain advanced features to maintain app performance on mobile devices. The file comparison utility is exclusively available in the desktop version. Furthermore, be aware that activating the AI add-on on your mobile app will not enable this missing feature.
Upload the two PDF files you wish to compare from your iOS device to a cloud service such as Adobe Document Cloud, iCloud Drive, or Google Drive so they are accessible on your computer.
Launch the Adobe Acrobat Pro application on your Windows or Mac computer.
Click on the 'Tools' tab located at the top left of the application window, scroll down, and select 'Compare Files'.
Click 'Select File' on the left to choose your older document, and click 'Select File' on the right for the newer document. Finally, click the blue 'Compare' button to generate a summary of all changes.
Manage and Edit PDFs Seamlessly Across Devices with WPS Office
If you are tired of feature limitations on mobile devices, try WPS Office. It provides a lightweight, highly compatible, and free alternative for managing all your document needs.

- 1. Download for iOS or PC: Search for WPS Office in the Apple App Store, or visit the official WPS website on your desktop.
- 2. Sign in to sync: Create or log into your WPS account to enable cloud syncing across your mobile and desktop devices.
- 3. Open and edit PDFs: Tap on your PDF file within the app to utilize the robust annotation, editing, and conversion tools.
Frequently Asked Questions
Can I use the AI assistant in Acrobat iOS to find differences in two PDFs?
No, the AI add-on in Acrobat Pro for iOS is designed for summarizing single documents and chatting with your PDF. It cannot cross-reference or compare two different PDF files.
How can I view two PDFs side-by-side on an iPad?
While automatic comparison isn't available, you can use iPadOS Split View. Open your PDF reader, tap the multitasking dots at the top of the screen, select Split View, and open another instance or a second PDF app to view both files side-by-side.
Will Adobe add the compare feature to the iOS app in the future?
Adobe has not released an official timeline for bringing the full file comparison tool to Acrobat Pro for iOS. For now, the desktop application remains the official method for this task.
