Over the past year I've manually combined instructor evaluations eight times. Show me the recurring bottlenecks in how…
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.
Combining files rarely makes the PDF smaller because it just adds all the content together. It does not compress or optimize the files during the combine process. If your combined PDF is too large, you should compress it after you have finished combining all the files. This will reduce the file size without losing important content.
The 'Combine PDF' operation in the Adobe API lets computer programs combine up to 20 files into one PDF automatically. You can also choose specific page ranges from each file to include. This is useful for developers who want to build tools that combine documents without needing to open Acrobat.
No, if your source files already have page numbers, the combined PDF will likely have page numbers that restart with each new original document. Acrobat does not automatically make them continuous. After combining, you will need to add new, continuous page numbers to the entire PDF to have a single, flowing sequence.
