Open Adobe Acrobat.
Go to File > Combine Files.

This runs in the Acrobat app - there is no separate API for this task.
Keeping 'Preserve Bookmarks' on is important because it makes each original file a top-level bookmark in your new combined PDF. This means you can easily navigate through your large document by clicking on the file names in the bookmarks panel, making it much easier to find specific sections.
Merging files rarely makes the PDF smaller; it usually keeps the same size or gets larger. If your combined PDF is too big, you should compress it AFTER you have merged all the files. Acrobat has a 'Reduce File Size' option that can help make your document smaller for sharing or storage, without losing too much quality.
Yes, the Combine Files feature in Acrobat is designed to work with many different file types. You can add Word documents, Excel spreadsheets, PowerPoint presentations, image files, web pages, and existing PDFs. Acrobat will convert them all into pages within a single new PDF document.
If your original documents already had page numbers printed on them, combining them will often result in those numbers restarting with each new document. This is because the 'Combine Files' feature merges the pages as they are. To fix this, you will need to add continuous page numbers to the combined PDF after it's created, overriding the old ones.
