Open .DOCX files online
A .docx file is a Microsoft Word document in the Office Open XML format — the default since Word 2007. Drop it on the page and ZipTool converts it to readable text right in your browser: headings, lists, and tables keep their structure, and the extracted plain text can be downloaded as .txt or found by content search. Nothing is uploaded and nothing is installed.
Under the hood a .docx is a ZIP container holding XML parts (word/document.xml carries the body text), which is exactly why a browser-based reader can parse it locally. The conversion here deliberately keeps text and structure and drops embedded images — an honest trade that keeps even large documents fast and private.
What is a `.docx` file?
Office Open XML (OOXML) stores a Word document as a ZIP of XML parts: the body text in word/document.xml, styles, headers and footers, and any embedded media as separate parts, tied together by relationships. The format became an ECMA/ISO standard (ECMA-376) and is what Word, Google Docs, LibreOffice, and Pages all write by default today.
MIME type: application/vnd.openxmlformats-officedocument.wordprocessingml.document. A .docx can be password-encrypted (those refuse honestly here), and the legacy binary .doc from Word 97–2003 is a different format entirely — re-save it as .docx to read it in a browser.

- Contracts and other shareable documents

Open `.docx` without uploading
Most "open docx online" sites work by uploading your file to a server and processing it there. ZipTool does the opposite: it loads its parser once, then reads your .docx locally in the browser tab. The contents stay on your device.
You can prove that in seconds. Open the page, press F12 for DevTools, switch to the Network tab, and open your file — no request carrying the file's contents is sent. You can also turn off Wi-Fi after the page loads and the file still opens. See security and privacy for the full picture.
Frequently asked questions
How do I open a .docx file online?
Drag the .docx onto the page (or click to browse, or paste a URL). The document converts to readable text in your browser — headings, lists, and tables keep their structure — and you can download the extracted text as .txt. The file is never uploaded.
Can I read a .docx without Word installed?
Yes. Word is not needed and neither is any other Office suite: the conversion runs entirely in your browser tab. If you also need to edit the document, open the downloaded .txt in any editor, or open the .docx itself in the free Office viewers or Google Docs.
Are embedded images shown?
No — this viewer keeps text and structure (headings, lists, tables) and drops embedded images. That keeps photo-heavy documents fast to open and completely private. The text itself, including captions and alt text where present, is preserved.
Can it open an old .doc file?
Not directly. The legacy binary .doc (Word 97–2003) is a different format with no open-source in-browser reader. Re-save it as .docx in Word, LibreOffice, or Google Docs, then drop it here — you will get an honest notice saying exactly that if you try.
Do you upload my .docx?
No. The document is converted entirely in your browser; its contents are never sent to a server, never stored, and never handed to a third party. Confirm it in DevTools — the Network tab shows no upload — and by disconnecting from the internet after the page loads: reading keeps working.
