Make your PDFs easier to share. Learn how to split and merge PDF documents quickly.

Do you have a PDF with a lot of pages, but not every page in it needs to be sent over, so you’d like to split the PDF? Or do you have multiple files that are similar and want to merge PDFs before sending them? PDFs make sharing documents fast — but there’s a way you could make the process even faster. A PDF merger and splitter lets you divide or combine PDFs to share them even more efficiently. Let’s look at how to split and merge PDFs with Adobe Acrobat.

Why would I need to split PDFs?

There are a variety of reasons why you may want to split a PDF. Perhaps you created an eBook for your company, and a co-worker only needs to read a particular section to gather information they need. You could split the eBook saved as a PDF to give them only the necessary chapter. Maybe your PDF is a larger file size with a lot of different sections. You could split up the PDF and send it in separate sections in order to share it more easily, as emails have a limited capacity for attachment sizes.

Why would I need to merge PDFs?

By merging multiple files into a single PDF, you can store and review them more easily. Keeping the content all in one place makes it less likely to get lost. Merging a PDF allows you to share files without worry and makes it easier for the viewer to find the information they need. By eliminating the need to organize multiple documents, merging your PDFs saves time that you could spend working on other projects. Combining files into PDFs leaves more space available on your device and in your email inbox and prevents the need to manage multiple files.

PDF too large now? Resources to compress files.

Compressing your files is a great way to save storage space on your computer and share files easily, as email inboxes typically have a size limit. Files can be shared quickly, and you can have more room on your device for all your other important files.

You can choose how much you would like to compress your file, with smaller sizes giving you the highest quality PDF and larger sizes giving you a standard quality PDF:
