How to Combine PDF Files Without Acrobat

Most users think that the only way to merge PDF files is to use Adobe Acrobat. However, you would need to pay for a subscription to use the feature.

It’s a good thing that you can now use third-party programs to combine PDF files. The best part? Some of these tools are free.

  1. Find an alternative PDF merger tool online that’s compatible with your device and operating system. Download the app or access it via the web, if applicable.
  2. Upload the PDF files that you want to merge.
  3. After uploading the files, rearrange them in the order that you want them to appear in the final document.
  4. Then, click the merge button. The tool should generate a new PDF file with the combined information.
  5. Download the merged file to your device.

It’s that easy. However, keep in mind that free tools often have limitations. For example, you might only be able to merge a certain number of pages or files. You may also have to deal with watermarks. Other apps may ask you to provide your email address before downloading the file.
