Question details
The user needs to know how to add and access Adobe Reader or the Fill and Sign options in the Safari share menu when attempting to open a PDF attachment from an email.

- Product
- Safari / Adobe Acrobat Reader
- Device & OS
- iPhone / iOS
- Scenario
- Opening a PDF attachment from a web-based email account accessed via the Safari browser on an iPhone.
- Observed behavior
- The Safari share button does not visibly display Adobe Reader or Fill and Sign as default options for handling the opened PDF document.
Ensure that the Adobe Acrobat Reader app is successfully installed on your iPhone and updated to the latest version via the App Store before attempting to share PDFs from Safari.
Use the 'Copy to Adobe Acrobat' Option in the Safari Share Menu
Access the extended share sheet options in iOS Safari to route your PDF document directly into the Adobe Reader application.
By default, Safari uses its built-in preview tool to display PDFs. To use third-party apps like Adobe Reader, you need to trigger the iOS share sheet and locate the specific copy command.
Navigate to your email inbox using the Safari browser and tap on the PDF attachment to open it in preview mode.
Tap anywhere on the open PDF document on your screen. This action will bring up a secondary top toolbar or the bottom navigation bar, depending on your iOS version.
Tap on the Share icon (a square with an upward arrow) or tap 'More' located at the top left of the window.
Look through the horizontal row of app icons for the red Acrobat icon and select 'Copy to Adobe Acrobat'. If you do not see it immediately, swipe left on the app row to scroll right and view more available options.

Open and Edit PDFs Easily with WPS Office for iOS
Skip the hassle of missing share menu options. WPS Office for iOS provides a seamless, all-in-one platform to open, read, annotate, and sign PDF files directly from your Safari browser, email, or local storage.
- 1. Install WPS Office: Download and install the free WPS Office app from the Apple App Store onto your iPhone.
- 2. Open the PDF in Safari: Tap the PDF link or email attachment in your Safari browser to preview the document.
- 3. Share to WPS Office: Tap the iOS Share icon, scroll through the app list, and select 'WPS Office' (or 'Copy to WPS Office') to immediately open and begin editing your PDF.

Frequently Asked Questions
Why isn't Adobe Reader showing up in my iPhone share menu?
If Adobe Reader is not visible in the share sheet, you may need to scroll to the far right of the app row, tap the 'More' button (three dots), and tap 'Edit' at the top right. From there, you can toggle the switch next to Adobe Acrobat to enable it in your share menu.
Can I make a third-party PDF reader the default viewer on my iPhone?
iOS does not currently allow you to change the system-wide default PDF viewer from the built-in Safari or Books preview. However, you can consistently choose the 'Copy to...' option from the share menu to route files to your preferred app.
How do I sign a PDF I received in Safari?
First, use the share menu to open the PDF in a dedicated PDF application like Adobe Reader or WPS Office. Once the document is open in the app, you can use the built-in 'Fill & Sign' or 'Annotation' tools to draw or insert your signature.
