Or, you want to combine PDFs to create a product portfolio or cut down on file clutter. For whatever use, you can do the job in Adobe Acrobat.

Merging multiple PDFs into a single PDF shouldn't be stressful. Both the desktop Adobe Acrobat and Acrobat online tool can free you from the task.

How to Combine PDF Files in Adobe Acrobat

Adobe Acrobat is always considered the best PDF software to combine PDF files. The software from the creator of PDF enables you to combine entire PDFs into one and merge specific pages from each PDF. You can delete and reorder PDF pages before finalizing the Adobe PDF combining process. The software also lets you combine Word, Excel, PowerPoint, or image files into a PDF.

Tips: Before combining files, you can double-click a PDF to expand its pages, remove, and rearrange specific pages, then collapse the reorganized pages. This provides a way to merge only necessary pages in a PDF with another file.

Both Adobe Acrobat Standard and Pro DC (premium version of Adobe Reader) allow you to combine PDF files using the above method, and they are available for free download on Windows or Mac. To merge PDF files on a Mac device, you’ll need the Adobe Acrobat Pro DC software. The free Adobe Reader only supports reading, signing, and annotating PDFs, and doesn’t has a tool for PDF combination.
