Merge Word Documents – Free Online Tool

Combine multiple Word documents into one .docx without losing formatting, styles, or images. The merger inserts a page break between sources by default, keeps each document's heading hierarchy, and produces a real Microsoft Word file you can keep editing afterwards.

• Open-and-go: bookmark the page once and never look for an alternative
• Instant results — no waiting on a server or upload progress bar
• Touch-friendly UI, fine on phones for on-the-go edits
• Built on SheetJS / pdf.js / OOXML — the same libraries used by serious desktop tools
• Auto-detects encoding (UTF-8, Shift_JIS, GBK, Vietnamese) for CSV imports

1. Upload multiple Word documents
2. Arrange files in order
3. Click "Merge Documents" button
4. Download the combined Word file

• Assembling book chapters into a manuscript
• Combining proposal/SOW sections written by different authors
• Consolidating weekly meeting notes into a quarter recap
• Merging legal contract clauses into a single agreement
• Assembling student assignments into one submission

Headings look inconsistent after merge

Each source defined Heading 1 differently. In the output, redefine Heading 1 once (Home → Styles) and Word will normalise all sources.

Images shifted or got cropped

Switch image anchoring from "in line with text" to "wrap text" in the source files before merging — floating images survive merges better.

Page breaks too aggressive

Toggle the page-break-between-sources option off and the merger will only insert a section break, which respects the next paragraph's before-break setting.
