Open Adobe Acrobat Pro.
Go to the File menu and select Create, then choose Combine Files into a Single PDF….
In the Combine Files window, click Add Files… and select all PDFs you want to merge, including those containing form fields.
Best practiceYou can select multiple files at once by holding Ctrl (Windows) or Command (Mac) while clicking.
Arrange the files in the desired order using the move up/down options.
If you want to preserve interactive form fields (so they remain fillable), click Options… and ensure the option to retain form fields is checked.
CautionIf multiple PDFs use the same form field names, data may be overwritten or fields may be merged across documents.
If you want to flatten all form fields (make them non-interactive), combine the files first, then open the merged PDF, go to File > Print, and select Adobe PDF as the printer. In the print dialog, check Document and Markups, then print to a new PDF.
RecommendationFlattening is recommended if you want to prevent any further editing of form data.
To avoid field name conflicts when preserving fields, use the Prepare Form tool on each original PDF to rename fields uniquely before combining.
Best practiceRenaming fields before merging prevents data from one form instance from overwriting another.
Click Combine to merge the files according to your chosen settings.
Save the resulting PDF.
If your merged PDF has duplicate form field names, editing one field may update all fields with that name—rename fields beforehand to keep data separate.
This runs in the Acrobat app - there is no separate API for this task.
When you combine files, make sure to keep 'Preserve Bookmarks' turned on. This feature creates a top-level bookmark for each original file, making your new PDF simple to navigate. You can click these bookmarks to jump directly to the start of each section.
This issue can happen if there are problems with the internal structure of your original files. Acrobat might struggle to process them correctly. To fix this, try re-saving each source file using 'Save As' to refresh its structure. You can also add the files one by one instead of all at once, or try repairing your Acrobat installation.
In Adobe Acrobat, 'merging' and 'combining' PDFs refer to the same process: taking multiple separate PDF documents and joining them into a single, unified PDF file. The terms are often used interchangeably to describe this action of bringing different documents together.
No, if your original files already had printed page numbers, the combined PDF will likely show those numbers restarting with each new original document. To get continuous page numbers across the entire combined PDF, you will need to add new page numbers after the combining process is complete, overriding the old ones.
Combining files rarely makes the PDF smaller. After you have combined your files, you should use Acrobat's 'Optimize PDF' or 'Compress PDF' feature to reduce the file size. This step helps to make the document easier to share and store without losing too much quality.
