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.
If your original files already have page numbers, combining them will likely result in restarted page numbering for each new section. For example, if you combine three files, each starting with page 1, your final PDF will have three sets of 'page 1'. To fix this, you should add continuous page numbers to the combined PDF after you merge the files, which will override the old numbering and create a single sequence.
Combining files rarely makes the PDF smaller because it mainly joins documents without changing their internal data much. It's like putting several books on one shelf; the total content doesn't shrink. If you need a smaller file size after combining, you should use Acrobat's 'Compress PDF' feature afterwards. This tool actively reduces file size by optimizing images and removing hidden data.
Yes, when you use Combine Files, Acrobat converts all the different file types you add (like Word, Excel, PowerPoint, images, and web pages) into a standard PDF format. This means they will all appear correctly within the single PDF document, maintaining their original look and layout as much as possible. You should always review the final PDF to ensure everything converted as expected.
