Legal needs a secure, auditable bundle of signed vendor contracts and warranties by next Wednesday. I can collect PDFs…
Open Adobe Acrobat.
Go to File > Combine Files.
Click Add Files and select the PDF files you want to merge.
Arrange the files in your desired order by dragging and dropping them within the list.
Click Combine to merge the selected files into a single PDF document.
Save the new combined PDF to your preferred location.
You can preview and reorder files before combining to ensure the final PDF is in the correct sequence.
This runs in the Acrobat app - there is no separate API for this task.
This is a known issue with the Combine Files feature. It can happen if the source files have old or damaged internal structures. To fix it, try re-saving each of your original files using 'Save As' before combining them. This refreshes their structure and often solves the problem.
No, if your source documents already had page numbers, the combined PDF will likely show those original page numbers, meaning they will restart with each new document. To have continuous page numbers across the entire combined PDF, you will need to add new page numbers after the combining process is complete. Acrobat has a tool to add new, continuous page numbers to an existing PDF.
| Action | Goal |
|---|---|
| Merging (Combine Files) | To put many separate files into one single PDF document. |
| Compressing | To make a PDF file smaller in size, often by reducing image quality. |
It's a good idea to keep your original files for a few days. If you find a mistake in your combined PDF or need to make a small change, it's easier to re-combine the original files than to try and edit the large combined document. This saves you time and effort.
