2. Under Tools, click Combine files.
3. Select Add files and upload all the PDFs you want to merge. You can select up to 100 PDFs to combine this way and merge all PDFs at once.
4. Arrange as desired by dragging and dropping.
5. Click Combine files to complete.
6. Save your new PDF.

Once you've added the files you want to combine, simply select or drag and drop them into the order you need. The file that's at the top of your list will appear first in your merged PDF file.

With our Acrobat Merge PDFs tool, you can easily produce a combined, single PDF file of up to 1,500 pages. You can merge up to 100 PDFs, with each individual document limited to 500 pages.

You can then add, delete, move or rotate PDF pages in a flash. When your document is finished, share it with others so they can view and comment from different devices and browsers.
