DOCX Merge Tool
Combine Word documents into one file without copy and paste. Drop two or more .docx files, drag them into order, and the tool joins them at the level of the document structure: paragraphs and tables keep their formatting, numbered lists keep their own numbering, images, links and footnotes come along, and each document keeps its page size and margins in its own section. The result is a normal .docx file you can keep editing.
- Files stay on your device
- No sign-up
- Free to use
Drag the files into the order you want. The first document provides the headers, footers and the look of shared styles.

DOCX Merge Tool FAQ
Which document’s styles win?
The first document. When two documents define a style with the same name, such as Heading 1, the merged file uses the first document’s definition, as Word does with “Use destination styles”. Styles that exist only in later documents are added.
What happens to headers and footers?
The first document’s headers and footers are used throughout. Later documents keep their page size, orientation and margins in their own sections.
Are comments kept?
Comments of the first document are kept; comments of the later documents are not carried over. Their text stays.
Can I merge without page breaks?
Yes. Choose “Continue on the same page” and each document follows directly after the previous one.
Is there a limit?
Up to 30 documents of up to 50 MB each, depending on your device’s memory.
Are my files uploaded?
No. The merge happens in your browser.
How the merge works
Copying documents together in Word is easy for two short files and painful for ten long ones: list numbering continues where it should restart, styles change appearance, and page setups get mixed up. This tool merges documents the way Word’s own “Insert text from file” works internally, by combining the document packages.
A .docx file is a package of XML parts: the text, the styles, the list definitions, footnotes, images and relationships that tie them together. The merge takes the first document as the base and appends the body of each further document. Everything the appended text refers to is copied with new identifiers: images and charts become new parts, hyperlinks become new relationships, list definitions get new numbers so each list keeps its own numbering, footnotes are renumbered, and bookmarks and drawing ids are made unique.
Each appended document starts a new section that carries its own page size, orientation and margins, so a landscape appendix stays landscape. Headers and footers are inherited from the first document, which gives the combined file a consistent look.
After merging, the tool opens the result again to check that the package is complete and reports the number of words. Open the file in Word to update fields such as the table of contents, which Word recalculates on request.
To do the opposite, use the DOCX Split Tool; to combine PDFs, use Merge PDF.
