Question details

The user wants to open and view multiple PDF files simultaneously without the first document closing automatically.

How to Open Multiple PDF Files at the Same Time
Product
Adobe Acrobat Mobile App
Device & OS
Mobile (iOS / Android)
Scenario
Attempting to open a second PDF document while another PDF is already open on a mobile device.
Observed behavior
The mobile app automatically closes the first PDF file when the second PDF is opened due to missing multi-tab support.
Before you start

Verify whether your current PDF reader application natively supports multi-tab browsing. If you are on a mobile device, ensure you have access to a desktop computer for alternative multi-file viewing.

Solution 1Recommended

Use a Desktop PDF Reader for Simultaneous Viewing

Since most mobile versions of Adobe Acrobat do not support opening multiple files at once, switching to the desktop version allows you to view multiple PDFs using a tabbed interface or separate windows.

The inability to open multiple PDFs simultaneously on mobile is an app limitation designed to optimize mobile memory and screen space, rather than an issue with the PDF files themselves.

1
Transfer the PDF files

Move the PDF documents from your mobile device to your desktop computer using cloud storage (like Google Drive or Dropbox), a USB cable, or email.

2
Open the first PDF on desktop

Launch your desktop PDF reader, such as Adobe Acrobat or Reader. Click on 'File' in the top menu, select 'Open', and choose your first PDF file.

3
Open additional PDFs

Repeat the 'File' > 'Open' process to select a second PDF. The desktop application will open the new document in an additional tab or a new application window, allowing simultaneous viewing.

Tabbed Browsing: Most modern desktop PDF readers default to a tabbed viewing interface, making it easy to switch between multiple open documents just like a web browser.

Frequently Asked Questions

Why does my mobile PDF reader close the first file when I open a second one?

Many mobile PDF readers restrict you to viewing one document at a time to optimize limited device memory and screen space. This is a built-in limitation of the mobile application itself and does not indicate any corruption or issue with your PDF files.

Is there a way to view two PDFs side-by-side on a mobile device?

Yes. While a single app might not open two PDFs at once, you can utilize your mobile device's split-screen multitasking feature. Open one PDF in your primary PDF app, split the screen, and open the second PDF in a different application, such as a web browser or a secondary document viewer.

Can I merge multiple PDFs together to read them as one file on mobile?

Yes. If you frequently need to reference multiple documents and your app only supports single-file viewing, you can use PDF utility apps or free online tools to merge several PDFs into a single continuous file.
