I have to produce a single, paginated document for a submission in [hours=48] including the lab report, risk assessmen…
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 can happen if there's a problem with the original files or the Acrobat program. To fix this, try saving each original file again using 'Save As' before combining. If that doesn't work, add your files one by one. You can also try repairing your Acrobat installation from the Help menu.
No, combining files usually does not make the PDF smaller. The new file will be about the same size as all the original files put together. If you need a smaller file, you should compress the combined PDF after you create it.
| Feature | What it does | When to use it |
|---|---|---|
| Combine Files | Takes whole documents (like a Word file and a PDF) and puts them together into one new PDF. | When you have many different files and want to make one large document from them, keeping each as a separate section. |
| Merge Pages (Insert Pages) | Adds pages from one PDF into another existing PDF, usually in a specific spot. | When you already have a PDF and just want to add a few pages from another PDF into it, like adding an appendix. |
