Merge Word Documents — Free, Private, No Limits

Merge Word Documents combines two or more .docx files into a single Word document, in the order you choose. It's useful for assembling a final report from sections written by different people, or combining chapters into one manuscript file. Content is extracted and recombined locally in your browser, and the result downloads as a standard .docx file you can open in Word, Google Docs, or LibreOffice. There's no signup, no file size limit, and your documents are never uploaded to a server.
