How to merge documents into one

Quick answer

To merge documents into one, open them in the same editor and combine them in order: Word's Insert > Text from File for .docx files, copy and paste or tabs for a few Google Docs, or an add-on such as Merge Docs Pro when you need to combine dozens of files and export them as PDF, Word or EPUB.

These guides cover every way to combine files into a single document, from the built-in options in Microsoft Word and Google Docs to merging Markdown, PDF and other formats. Each guide explains when the built-in method is enough and when a dedicated tool saves time.
