Question details
Users want to know why PDF editing or viewing toolbars appear when they open an email attachment and how to hide them for a cleaner reading experience.

- Product
- PDF Viewer
- Device & OS
- not provided
- Scenario
- Opening and viewing a PDF attachment directly from an email client or web browser.
- Observed behavior
- When opening a PDF received via email, a toolbar or application interface is visible alongside the document, leading users to believe the tools are embedded within the file itself by the sender.
Understand that these toolbars are a feature of your local PDF viewer or web browser, not something embedded into the document by the sender. Identifying whether you are viewing the PDF in a browser or a desktop app will help you manage these settings.
Download the Attachment and Open with a Dedicated PDF Reader
Bypass the email client or browser's built-in preview by downloading the PDF and opening it in a standalone PDF application.
Most webmail services automatically open PDFs in a built-in browser viewer, which overlays its own unchangeable toolbars. Downloading the file gives you full control over how the document is displayed.
Click the download icon (usually an arrow pointing downward) on the email attachment instead of clicking the preview thumbnail.
Navigate to your computer's Downloads folder to find the saved PDF document.
Right-click the downloaded file, select 'Open with', and choose a dedicated PDF application to view it without browser-specific email overlays.

Hide the Application Toolbar in Your Browser or Viewer
Adjust the view settings of your current browser or PDF application to hide the distracting toolbars.

Frequently Asked Questions
Can the sender remove the PDF tools before emailing the file?
No, the sender cannot control which PDF tools appear on your end. The toolbars and menus are generated by your own device's PDF application or web browser, not the document itself.
Why do PDFs look different in my webmail compared to my desktop application?
Webmail services like Gmail or Outlook use built-in browser PDF previewers, which have their own unique toolbars and layouts. Desktop applications provide a different, customizable, and usually more comprehensive interface.
How do I stop PDFs from opening in my browser by default?
You can change your computer's default application settings. Right-click a PDF file on your computer, select 'Open with', choose 'Choose another app', select your preferred PDF reader, and check the box that says 'Always use this app to open .pdf files'.
