How do I make sure the files combine in the correct order?

When you are in the 'Combine Files' window, you will see small pictures of your files. Drag these small pictures (thumbnails) up or down to change their order. The first file at the top will be the first page in your new PDF, and so on.

What is the 'Preserve Bookmarks' option when combining PDFs?

The 'Preserve Bookmarks' option helps you navigate your new combined PDF. When it is on, each original file you added becomes a main bookmark in the final PDF. This means you can quickly jump to the start of each original document within the new single PDF, making it easy to find different sections.

If my combined PDF is very large, can I make the file size smaller?

Yes, combining files usually does not make the file size smaller. After you combine your files, you can use Acrobat's 'Optimize PDF' or 'Compress PDF' feature. This tool helps reduce the file size without losing too much quality. It is a good step to take if you need to email the PDF or upload it to a website with file size limits.

Why did my combined PDF only show the first file many times?

This is a known issue with the Combine Files feature. It can happen if the original files have internal problems or old structures. To fix this, try saving each source file again using 'Save As' before combining them. This refreshes their internal structure. Also, adding files one by one instead of all at once can help prevent this problem.

What is the difference between combining files and merging pages?

Feature What it does Best for. Combine Files Puts entire separate documents (like a Word file, an Excel file, and a PDF) into one new PDF. Creating a single packet from many different document types. Merge Pages (Insert Pages) Adds pages from one PDF into an existing PDF at a specific spot. Adding a few pages to an already existing PDF document.

FAQ

about this task

In Adobe Acrobat, you can use the 'Combine Files' tool to put several files together into one PDF. After combining, you can use the 'Bookmarks' panel to add a bookmark at the start of each original file so you can easily find them.

Adding bookmarks helps you quickly jump to the start of each original file inside the new, combined PDF. It makes it easier to find and read different sections.

Yes, Adobe Acrobat lets you mix different types of files, like Word documents, images, and PDFs, into one PDF. Each file will become a part of the new document, and you can add bookmarks for each.

Bookmarks are clickable links you see on the side of your PDF that let you jump to certain pages. A table of contents is a list inside the document, usually at the start, showing where each section begins.

Bookmarks save time because you can click and go straight to the part you need, instead of scrolling through many pages to find each section.
