How to use the Merge Word Documents
Add your Word files by dropping them on the box or clicking Choose Word files. Add more at any time.
Put them in order by dragging the cards or using the arrow buttons. The first file is the base: its page setup, headers and styles are used.
Choose what goes between documents: a page break, a section break (each file keeps its own layout) or nothing.
Press Merge documents, then Download merged .docx and open it in Word, Google Docs, LibreOffice or Pages.
How the documents are combined
A .docx file is a ZIP package of XML parts: the main text, styles, list definitions, pictures, headers, footers and notes. Merging is more than gluing text together. For every file after the first, this tool:
copies the body content (paragraphs and tables) to the end of the first document, in the order you set;
copies the pictures, charts, embedded objects, headers and footers it uses, renaming them so nothing collides, and rewrites the internal links (relationship IDs) to point at the copies;
renumbers list definitions, footnotes, endnotes, comments and bookmarks so that numbered lists restart correctly and every note stays with its own text;
adds any styles that the first document does not already define;
inserts the break you chose between files.

Tips for a clean merge
Pick the right first file. It sets the default font, heading look and page layout. Drag the file whose design you like best to position 1.
Add a table of contents afterwards. Tick "Add each file name as a heading", merge, then in Word use References > Table of Contents to list every part.
Page numbers continue through the whole document with a page break. With section breaks, Word may restart numbering in sections whose source file was set to start at 1; change it under Page Number > Format Page Numbers.
Fonts are not stored inside .docx files. If a file uses a font that is missing on the computer that opens the merged file, a similar font is substituted.
Frequently asked questions
How do I merge several Word documents into one?
Add the .docx files on this page, drag them into the order you want, pick a page break or section break between them and press Merge documents. The combined file downloads as a single .docx. In Word itself you can do the same with Insert > Object > Text from File, one file at a time.
Is formatting kept when I combine Word files?
Text formatting, pictures, tables, lists, hyperlinks, footnotes and endnotes are carried over. If two files use a style with the same name, for example Normal or Heading 1, the merged document uses the first file's version of that style, which is also what Word does when you insert one document into another. Styles that exist only in a later file are copied in unchanged.
What is the difference between a page break and a section break?
A page break simply starts the next file on a new page, and the whole result uses the first file's page size, margins, headers and footers. A section break makes every file its own section, so each one keeps its own paper size, orientation, margins, headers, footers and page numbering settings.
Are my documents uploaded to a server?
No. The files are read and combined by JavaScript in your browser, and the merged .docx is created on your device. Nothing is sent anywhere, so it is safe for private letters, contracts and school work.
Can I merge old .doc files or PDFs?
This tool works with .docx files, the format used by Word 2007 and later, Google Docs downloads and LibreOffice. Open an old .doc file in Word, Google Docs or LibreOffice and save it as .docx first. To combine PDFs, use a PDF merger instead.
Is there a limit on the number or size of files?
There is no fixed limit. Because everything happens in your browser, the practical limit is your device's memory; dozens of normal documents, or a few large ones full of photos, merge in a few seconds.
What happens to comments and tracked changes?
Comments are kept by default and stay attached to the same text; untick Keep comments to remove them. Tracked insertions and deletions are copied as they are, so you can still accept or reject them in Word after merging.
