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).
