Solution 1Recommended

Restart Device and Check the Expanded Share Menu

Sometimes iOS temporarily glitches and hides installed apps. Restarting your iPhone and checking the extended 'More' section of the Share menu often resolves this visibility issue.

The iOS Share sheet dynamically suggests apps based on your usage. If an app hasn't been used recently or the system cache encounters an error, the app might be hidden from the primary row.

1
Restart your iPhone

Restart your device to clear out any minor software glitches or stuck background processes affecting the Share sheet.

2
Trigger the Share menu

Open the app containing the PDF file (such as Mail, Safari, or Messages) and tap the 'Share' or 'Open In' icon.

3
Access more applications

Swipe left on the horizontal row of colored app icons until you reach the end, then tap the 'More' button (represented by three dots).

4
Add to favorites

Scroll down the list of suggestions to find your preferred PDF app. Tap 'Edit' in the top right corner, then tap the green '+' icon next to the app to add it to your favorites so it always appears.

Frequently Asked Questions

Why did my PDF reader suddenly disappear from my iPhone Share menu?

This typically happens after a major iOS update, if the app was automatically offloaded by iOS to save storage space, or due to a temporary glitch in the system's Share sheet cache. Checking the 'More' options or reinstalling the app usually restores visibility.

How do I make a specific app the default for opening PDFs on my iPhone?

Unlike Android or Windows, iOS does not allow you to set a system-wide default app for opening PDFs. However, by tapping 'Share', choosing 'More', and editing the app list to move your preferred PDF app to the top of your favorites, you can make it the most easily accessible option.

What should I do if the PDF app appears in the menu but the file still won't open?

If the application launches but fails to load the document, the PDF might be corrupted, extremely large, or password-protected. Try saving the file directly to your iPhone's 'Files' app first, then open your PDF reader and navigate to the saved file from within the application.
