We keep losing images and footnotes when we circulate chapter drafts. I’ve got time to change the system and want an a…
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.
Keeping 'Preserve Bookmarks' on is important for easy navigation in your new PDF. If your original files had bookmarks, this setting makes sure they are carried over. This means each source file will become a top-level bookmark in the combined PDF. You can then quickly jump to different sections of your long document.
No, if your source files already have printed page numbers, these will restart for each new file you combine. For example, if File A ends on page 10 and File B starts with page 1, the combined PDF will show page 10 from File A, then page 1 from File B. To get continuous page numbers, you need to add new page numbers to the combined PDF after you merge it.
Combining files rarely makes the file size smaller because it's adding content, not removing it. Each file brings its own data, fonts, and images. The tool focuses on putting them together. If you want a smaller file, you should compress the PDF *after* you have combined all the files. This will reduce the overall size of the new document.
In Adobe Acrobat, 'combining files' and 'merging files' refer to the same action. Both terms mean taking multiple separate documents or files and putting them together into one single PDF document. There is no functional difference between these two words when using Acrobat.
