Question details
The user is confused why the Combine Files option displays an 'Add' icon in Adobe Reader, even though the combining feature is included with their active subscription plan.

- Product
- Adobe Reader
- Device & OS
- not provided
- Scenario
- Attempting to merge multiple PDF documents into a single file using the Adobe Reader desktop application.
- Observed behavior
- Instead of performing the action natively within the application, the Combine tool displays an 'Add' button that redirects the user to a web browser.
Ensure you have a stable internet connection and are actively signed into your Adobe account, as Adobe Reader relies on online web services to process and combine PDF files.
Access the Web-Based Combine Feature via the Add Icon
Clicking the 'Add' icon is the intended design for Adobe Reader, which automatically redirects you to Adobe's online PDF services to complete your task.
In Adobe Reader, advanced features like combining PDFs are not processed locally on your device's hardware. Instead, the application connects to the Adobe Document Cloud.
When you click the 'Add' button, the software intentionally opens your default web browser so you can upload and merge your files securely online using their web portal.
Open Adobe Reader, navigate to the Tools menu, locate the Combine Files option, and click the 'Add' icon.
Allow the application to launch your default web browser. You will be automatically redirected to your Adobe Document Cloud account.
Follow the on-screen instructions in the web interface to upload your PDF files, arrange them in the desired order, and click the option to combine them into a single document.

Merge PDF Files Directly within WPS Office
Unlike Adobe Reader, WPS Office allows you to combine multiple PDF documents natively on your desktop without redirecting you to a web browser. Enjoy seamless, offline PDF merging with a single click.
- 1. Open WPS Office: Launch the WPS Office desktop application and open your PDF document, or navigate directly to the PDF Tools tab from the home screen.
- 2. Select the Merge PDF Tool: Click on 'Merge PDF' from the top toolbar or the dedicated PDF tools menu to open the document merging dialogue box.
- 3. Add Your Files: Click 'Add Files' or simply drag and drop all the PDF documents you wish to combine into the designated staging area.
- 4. Adjust Order and Combine: Arrange the uploaded files or specific pages in your preferred sequence, then click the 'Merge' button to instantly create a single PDF file offline.

Frequently Asked Questions
Why does Adobe Reader open my web browser when I try to combine PDFs?
Adobe Reader is primarily a free viewing application. Premium features, such as combining PDFs, are hosted on Adobe's Document Cloud infrastructure. The application acts as a portal, redirecting you to your web browser to utilize these online services.
What should I do if the web page fails to load after clicking Add?
If the web service is temporarily unavailable or the page fails to load properly, sign out of your Adobe account within the Reader application, restart the software, sign back in, and click the Add button again.
Can I combine PDF files offline without using a web browser?
Adobe Reader requires an active internet connection and a web browser to combine files via its cloud service. To combine PDFs completely offline and natively on your device, you will need a dedicated desktop PDF editor like WPS Office or Adobe Acrobat Pro.
