In the past year I assembled five client deliverables and each time clients asked for clarifications about provenance …
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 issue can happen if there's a problem with the structure of the original files. Acrobat might struggle to process them correctly. To fix it, try re-saving each source file using 'Save As' before combining. This often refreshes the file's internal structure and resolves the problem.
The 'Combine PDF' API is a tool for developers that lets computer programs combine PDF files automatically. Instead of manually clicking in Acrobat, you can write code to merge documents. This is useful for tasks that happen often or involve many files, like creating daily reports or processing large batches of documents without human input. It can combine up to 20 files.
No, if your original documents already had page numbers, the combined PDF will likely show those numbers restarting with each new document. For example, if you combine two documents, both starting at page 1, your combined PDF will have two sets of 'page 1'. You will need to add new, continuous page numbers to the combined PDF after merging.
Merging files rarely makes the final PDF smaller. Usually, the size stays about the same or even gets a little bigger. If you need a smaller file, you should compress the combined PDF after you have finished merging all your documents. This will help reduce the overall file size.
