Fix Signed PDF Files Not Sending Through WhatsApp | WPS Support
Question details
Users are unable to send signed PDF documents directly through WhatsApp, as the app sends an installation link instead.
- Product
- Adobe Acrobat Reader Mobile
- Device & OS
- iOS
- Scenario
- Attempting to share a digitally signed PDF file with contacts using WhatsApp.
- Observed behavior
- The recipient receives an Adobe app installation link instead of the actual signed PDF document.
Ensure you have a stable internet connection and verify that your device has enough storage space to download application updates.
Update Acrobat Reader Mobile to the Latest Version
Updating to version 23.07.01 or newer resolves the known bug that causes the app to generate a link instead of attaching the file.
This sharing glitch is a recognized issue in older builds of Acrobat Reader Mobile. The development team has patched this bug starting from version 23.07.01.
Navigate to the App Store on your iOS device and tap your profile icon at the top right corner.
Scroll down to see pending updates and release notes. Look for Adobe Acrobat Reader in the list.
Tap the 'Update' button next to Acrobat Reader to install version 23.07.01 or later. If you only see 'Open', the app is already fully updated.
Launch the newly updated app, open your signed PDF, and share it via WhatsApp. The actual document will now be sent.
Save a Flattened Copy Before Sharing
If you cannot update the app immediately, flattening the PDF ensures the signature is baked in and bypasses the app's smart-link feature.
Easily Sign and Share PDFs with WPS Office
Avoid unwanted app-link sharing issues entirely. WPS Office allows you to securely sign PDF documents on your mobile device and instantly share the actual file directly to WhatsApp without complications.
- 1. Open your PDF in WPS Office: Launch the WPS Office app on your mobile device and open the PDF document you need to sign.
- 2. Add your Signature: Tap the 'Tools' menu, select the 'PDF Signature' feature under the Annotation tab, and draw or insert your signature.
- 3. Save the Document: Tap 'Done' to apply the signature and save the document locally to your device.
- 4. Share Directly to WhatsApp: Tap the 'Share' icon at the bottom, choose 'Share as File' (instead of a link), and select WhatsApp to send the actual signed document.
Frequently Asked Questions
Why does my PDF reader send a link instead of the file?
Many modern PDF reader apps default to cloud sharing to save mobile data and storage. They upload the file to their server and send a link. If the recipient doesn't have the app, it directs them to an installation page. Choosing 'Share a Copy' or 'Share as File' usually forces the app to send the actual document.
Is there a file size limit for sending PDFs on WhatsApp?
Yes, WhatsApp currently allows you to share documents, including PDF files, up to 2GB in size. If your signed PDF exceeds this limit, you will need to compress it before sending.
Can recipients view signed PDFs without a special app?
Yes, standard digitally signed PDFs can be opened by most built-in mobile document viewers, web browsers, or lightweight apps like WPS Office without needing specialized software.
Will my digital signature disappear if I share the file through WhatsApp?
No, a properly embedded digital signature becomes a permanent part of the PDF document. As long as the actual file is shared (and not just an un-synced cloud link), the signature will remain fully visible to the recipient.
