How do I combine several files into one PDF using Adobe Acrobat?

Open Combine Files in Acrobat. Add your files (Word, Excel, images, PDFs). Drag files to arrange the order. Click Combine. Save your new PDF.

If my combined PDF only shows the first file, what should I do?

Re-save each file using 'Save As' before combining. Try adding files one by one instead of all at once. Use 'Help > Repair Installation' in Acrobat if the problem continues.

Why should I keep my original files after merging PDFs in Acrobat?

You may need to fix or redo the merge if there is a mistake. Original files help if you need to make changes later. Sometimes merging does not work right the first time.

How is combining files in Acrobat different from compressing a PDF?
