Solution 1Recommended

Update Acrobat and Use the Native iOS Share Menu

Software bugs in older versions of the app can disrupt the sharing process. Updating the application and utilizing the system-level iOS share sheet often bypasses in-app sharing glitches.

Adobe frequently releases patches to fix compatibility issues with the latest iOS versions. If the in-app 'Send' button throws an error, the native iOS 'Share' interface is a highly reliable alternative.

1
Update the App

Open the App Store on your iPhone, tap your profile icon at the top right, scroll down to check for updates, and tap 'Update' next to Adobe Acrobat if available.

2
Open the Document

Launch the Adobe Acrobat app and open the specific PDF file you are trying to send.

3
Access More Options

Tap the three-dot menu icon located in the top right corner of the screen to reveal the document options.

4
Trigger the iOS Share Sheet

Select 'Send a Copy' from the list. This will bring up the native iOS Share menu (a square with an upward-pointing arrow).

5
Select the Destination

Choose your preferred sharing method from the iOS menu, such as AirDrop, Messages, or Mail, to successfully send the document.

Frequently Asked Questions

Why does Adobe Acrobat say 'error' when I try to send a PDF via email?

This often happens if the default Mail app on your iPhone is not set up with an active account, if the PDF file size exceeds the email provider's attachment limit, or if there is a temporary sync issue with Adobe Document Cloud.

How can I reduce the size of my PDF so it sends successfully on my iPhone?

Large files frequently fail to send over cellular networks. You can compress the PDF within Adobe Acrobat if you have a premium subscription, or use a free tool like WPS Office to compress the document before sharing it via email.

Where are downloaded PDFs saved on an iPhone by default?

By default, PDFs downloaded from Safari or received in messages are saved in the iOS 'Files' app under the 'Downloads' folder. You can open the Files app, locate the PDF, and use the iOS share button to send it directly without using a third-party app.
