How to Open PDFs in Adobe Acrobat by Default on iPhone 15
Question details
The user wants to know how to open PDF files in Adobe Acrobat instead of Apple Books or Files on an iPhone 15, and needs help fixing the inability to copy text from PDFs.
- Product
- Adobe Acrobat for iOS
- Device & OS
- iPhone 15 Pro Max / iOS
- Scenario
- Opening downloaded or emailed PDF documents and attempting to select, highlight, or copy text on a new iPhone.
- Observed behavior
- PDFs default to opening in system apps like Books or Files. Even when opened, text copying is restricted if the PDF is scanned, image-based, or secured by the creator.
Ensure you have the latest version of Adobe Acrobat installed from the App Store and verify that the PDF document is not protected with a password that restricts editing and copying.
Open PDFs in Adobe Acrobat via the iOS Share Menu
Because iOS does not provide a system-wide setting to change default file associations globally, using the Share menu is the most reliable method to consistently open PDFs in Acrobat.
Apple's iOS prioritizes native apps like Files and Apple Books for viewing PDFs. To bypass this, you must route the document to your preferred third-party application manually.
Open the Apple Files app, Mail, or the web browser where your PDF is currently saved or displayed.
Tap on the PDF to preview it, then tap the 'Share' icon (a square with an upward-pointing arrow) typically located at the bottom or top of the screen.
Swipe horizontally through the app icons and tap 'Acrobat'. If it is not listed, scroll all the way to the right, tap 'More' (the three dots), and select Acrobat from the extended list.
Enable Text Copying for Scanned or Protected PDFs
If you successfully open the PDF but cannot select or copy the text, the document may be a flat image or have security restrictions applied.
Use WPS Office to View, Edit, and OCR PDFs on iPhone
WPS Office is a comprehensive mobile suite that handles PDFs flawlessly on iOS. You can easily open PDFs via the Share menu, annotate documents, and use built-in OCR tools to extract and copy text from scanned files—all in one lightweight app.
- 1. Install the App: Download WPS Office for free from the Apple App Store on your iPhone.
- 2. Open PDF with WPS: Navigate to your PDF in the Files app, tap the Share icon, and select WPS Office from the app list.
- 3. Read and Annotate: Use the intuitive WPS PDF viewer to read, highlight, add signatures, or make annotations on your document.
- 4. Extract Text Easily: For scanned PDFs, select the OCR feature in WPS Office to instantly recognize and extract selectable text to your clipboard.
Frequently Asked Questions
Can I set a default PDF app in iOS settings?
No, Apple's iOS currently does not allow users to set a system-wide default application for opening PDF files. They will usually default to Apple's native Files or Books app. Using the Share menu is the official workaround.
Why can't I copy text from my PDF on my new iPhone 15?
If you cannot copy text, the PDF might be a scanned image rather than a text-based document, or the document's creator may have applied security restrictions preventing text extraction. You can use an app with OCR capabilities to make scanned text selectable.
How do I add an app to the iPhone Share menu?
Open a file and tap the Share icon. Swipe left on the row of app icons until you see the 'More' button (three dots). Tap it, then tap 'Edit' in the top right corner. You can use the green plus icons to add apps to your favorites and rearrange them for quick access.
