Combine PDF files with Adobe Acrobat

Combine with Adobe Acrobat Pro or Standard

1. Open Acrobat and select Tools → Combine Files.
2. Select Add Files and choose the documents you want to merge (PDFs, Word, Excel, images).
3. Drag the thumbnails to reorder pages as needed.
4. Select Combine — Acrobat creates a new merged PDF.
5. Save it with File → Save As and choose a destination.

Combine from File Explorer (right-click method)

1. Select multiple files in File Explorer while holding Ctrl.
2. Right-click → Combine files in Acrobat... (requires Acrobat to be installed).
3. Acrobat opens with those files pre-loaded — proceed from step 3 above.

Reduce file size after combining

Large merged PDFs can be compressed:

1. Open the combined file in Acrobat.
2. Select File → Reduce File Size (or Compress PDF in newer versions).
3. Choose the target quality and save.

If you do not have Acrobat

Use the PDF & Documents category in the Software Catalog to request an Acrobat licence, or ask the help desk about Nitro PDF as an alternative.
