  1. Open Adobe Acrobat DC if it is not already open.
  2. Select "File" and then "Create" > "Combine Multiple Files into a Single PDF" option. Alternatively, you may select the "Combine Files" option from the right-hand menu if you've already opened the file.
  3. Drag files into the "Add Files" box or use the "Add Files" buttons to do so.
  4. PDFs, images, PowerPoint presentations, emails, and other types of documents can all be selected at once.
  5. To merge multiple PDFs into one document, just select all of the files and then click "Combine".

Adobe Acrobat is no doubt a good PDF software. However, it is way too expensive and users can't afford it. Its features are too complicated for most users and some of the features are useless. That's why there are more and more PDF editors born in the market with better experience and lower prices. UPDF is the best Adobe Acrobat alternative. It is faster than Adobe Acrobat and it can open and edit very large PDF files easily. Below is a comparison chart between Adobe Acrobat and UPDF.

What are the Advantages of Merging PDFs

Transparency in Exchanging Data

It might be difficult to upload or attach many documents at once. There are a few email and social media sites that still limit attachments to one file, even though most of these platforms allow attachments of multiple files.

One of the simplest methods is to combine all of your files into a single PDF document. The documents may be merged into a single file and then uploaded to the appropriate platform without having to be sent one at a time.

Document Management Made Simple for Big Projects

Multiple teams and a plethora of documentation are frequently required for large-scale initiatives.

Routine reports on tasks, objectives, and statistics are frequently requested from individuals, groups, and departments.

Keeping track of all those documents without wasting time looking for them is a difficult task.

All of the reports should be combined into a single document and made available to each team in order to demonstrate the full scope of the study's findings and conclusions.

More Efficient and Smarter Printing

There are two circumstances in which a large number of papers must be printed:

  • You open your files one at a time by clicking "Open" on your computer's desktop.
  • It's easy to combine many files into a single document and print it out in a matter of minutes.

Aside from practicing patience, the only option one is worth pursuing. Don't waste any more time clicking away and losing sight of what you've already done, instead print once and spend your time on more essential matters instead.

Merging and Scanning

A single file is preferable for scanning a big amount of text, such as a 30-page contract or multiple pages from a book. However, the scanning process might be disrupted by faults or technological difficulties.

Scanning might be disrupted for any number of reasons. Keep scanning and saving the pages you've already scanned. The final step is to merge all of the files into a single PDF.
