Solution 1Recommended

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.

1
Open the PDF in Safari

Navigate to your email inbox using the Safari browser and tap on the PDF attachment to open it in preview mode.

2
Reveal the Secondary Toolbar

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.

3
Access the Share or More Options

Tap on the Share icon (a square with an upward arrow) or tap 'More' located at the top left of the window.

4
Select Adobe Acrobat

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.

App Visibility in the Share Sheet: If you still cannot see the Acrobat icon after scrolling, tap the 'More' icon (three dots) at the far right of the app list. This will let you edit your share sheet actions and toggle the switch to enable Adobe Acrobat.

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.
