How to Fix Cannot View PDF Attachments in Email

Product: PDF Viewer
Device & OS: not provided
Scenario: Attempting to open or view a PDF document attached to an email message.
Observed behavior: The PDF attachment appears blank, fails to open, or is completely not visible within the email application interface.

Before you start

Ensure that your internet connection is stable so the email attachment can download completely, and check if the issue occurs with all PDFs or just one specific file.

Solution 1Recommended

Verify and Update Your PDF Reader App

Outdated apps or missing default PDF viewers can prevent email attachments from opening correctly on your device.

Email applications often rely on external PDF readers to render complex documents. If your PDF reader is missing or outdated, attachments may display as blank pages.

Check for installed PDF apps

Look through your device to ensure a dedicated PDF viewing application, such as WPS Office or Adobe Acrobat Reader, is installed.

Update the application

Open your device's app store (Google Play Store or Apple App Store), search for your installed PDF reader, and tap 'Update' if a newer version is available.

Save and open manually

Instead of tapping the attachment directly in the email, select 'Save to device' or 'Download'. Then, open your PDF app and locate the saved file from your local storage.

Tip: Saving the file locally bypasses limitations or bugs that might exist in the email client's built-in previewer.

Solution 2

Clear Email App Cache and Test Alternative Files

Corrupted temporary data in your email app or a broken specific file might be causing the blank display.

Fast and Reliable PDF Reader

Open and View Any PDF Attachment using WPS Office

WPS Office provides a highly compatible and fast PDF reader that seamlessly integrates with your email clients, ensuring you never see a blank screen when opening important documents.

1. Download WPS Office: Download and install WPS Office from the official website or your device's app store.
2. Locate the Email Attachment: Open your email app and navigate to the message containing the problematic PDF attachment.
3. Download the PDF: Tap or click on the attachment and select the option to 'Save to Device' or 'Download'.
4. Open in WPS Office: Launch WPS Office, navigate to the 'PDF' tab, and select your newly downloaded file to view it instantly without errors.

Frequently Asked Questions

Why does my PDF attachment open as a completely blank page?

This usually happens if the PDF file was corrupted during download, your email app's built-in previewer doesn't support the specific PDF formatting used, or your device lacks a dedicated, updated PDF reader app.

How do I change the default app for opening PDFs from emails?

On most mobile devices, you can change the default app by downloading the PDF file, locating it in your file manager, long-pressing the file, selecting 'Open with', choosing your preferred app (like WPS Office), and setting it to 'Always'.

Can I view PDF attachments without downloading them to my local storage?

Yes, many email clients have built-in document previewers. However, for complex or securely encrypted PDFs, downloading the file and opening it in a dedicated PDF reader is recommended to ensure proper rendering and avoid blank screens.
