How to Merge PDFs Online

As we built our online PDF merging tool, we learned a very interesting fact: There are more than a dozen ways to say "merge a PDF." Whether you are looking to consolidate PDF files, collate a PDF, combine 2 PDFs into 1, safely stitch multiple PDFs together or a safe PDF stitcher, put multiple PDFs together, bundle .pdf files, stack a bunch of PDFs, join PDF pages,add one PDF file to another, digitally bind a PDF, save multiple PDFs as one, or group or batch PDF files ( ... whew!...) PDF.Live has you covered.

We’ve made the PDF merging process very simple. Simply locate the PDF file you want to merge on your device and follow the prompts to upload and retrieve your merged PDF file. Remember, the larger your file is, the longer it will take to merge.

The process is the same no matter what device you use — a Windows 10 or 11 computer, Mac laptop, Linux workstation, or a mobile device.

FAQs about PDF.Live’s PDF Online Merge Tool

How can I attach multiple PDFs together?

With any file merging tool, you’ll only be able to merge like files. So, PDFs merge with PDFs. If you need to add a Word Doc or an Excel sheet to your merged file, you’ll need to convert those to a PDF. Head to the home page to convert those to PDFs.

Can you combine PDF files with other files?

Most Apple and Windows computers come with technology that zips files into a single format, called a ZIP file (.zip). You can read more about that in our resource article about how to zip files. Note, though, that zipping files smooshes them into a single folder; it does not combine them into a single file. So if you combine two PDFs, a .doc and a .xls spreadsheet into a zipped format, when you unzip them, they'll still be two PDFs, a DOC and an XLS file.
