Change Default PDF App to Adobe Acrobat on Android
Use your Android system settings to clear your current default PDF viewer and assign Adobe Acrobat as the new default app for opening WhatsApp files.
Go to your Android device Settings, tap on 'Apps' or 'App Management', find your current default PDF viewer, select 'Open by default', and tap 'Clear default preferences'.
Open a WhatsApp chat, locate a received PDF document, and tap the file to open it.
When the 'Open with' menu appears, tap 'Adobe Acrobat' from the application list and select 'Always' to save it as your default PDF reader.

Open WhatsApp PDFs in Adobe Acrobat on iPhone or iPad
Since iOS restricts setting third-party apps as universal defaults for document types, use the iOS Share menu within WhatsApp to route files to Adobe Acrobat.
Use WPS Office as Your Default Mobile PDF Reader
WPS Office offers a powerful, lightweight, and fast mobile PDF reader that flawlessly integrates with WhatsApp. You can effortlessly set it as your default app for opening, viewing, editing, and annotating PDFs on the go.
- 1. Install WPS Office: Download and install WPS Office from your device's native app store (Google Play or Apple App Store).
- 2. Clear current Android defaults: Navigate to your Android device Settings, locate your current PDF app under the 'Apps' section, and tap 'Clear defaults'.
- 3. Trigger the app prompt: Tap any PDF file in a WhatsApp conversation to trigger the 'Open with' selection menu.
- 4. Set WPS Office as default: Select 'WPS Office' from the list of available apps and tap 'Always' to ensure all future PDFs open quickly within WPS.

Frequently Asked Questions
Why doesn't the 'Open with' prompt appear when I tap a PDF in WhatsApp on Android?
This occurs when another application is already designated as the default PDF viewer on your system. You need to navigate to your device's Settings > Apps, locate that specific app (such as Google Drive PDF Viewer), and clear its default settings so the prompt can display again.
Can I make Adobe Acrobat the automatic default PDF viewer on iOS devices?
No, iOS does not currently support setting a third-party application like Adobe Acrobat as a system-wide default for opening PDF files. You are required to use the Share sheet each time you want to open a document in a non-Apple application.
What should I do if the PDF downloaded from WhatsApp is corrupted or won't open in my reader?
First, ask the sender to re-send the file as the download may have been interrupted. If the file still fails to open, ensure your PDF viewer is updated to the latest version, or attempt opening the file manually from your device's local storage directory (Internal Storage > Android > media > com.whatsapp > WhatsApp > Media > WhatsApp Documents).
