How to use split word documents

  1. Choose your DOCX file. Drop the file onto the upload area or pick it from your device. The file is sent over HTTPS, processed, and deleted as soon as the result is written.
  2. Set the options. Adjust the settings shown for split word documents. The defaults suit most files, so you can usually leave them alone.
  3. Check and save the result. Run the tool and download the modified DOCX file. Compare it against your original before you rely on it — conversions do not always carry every detail across.

Privacy

When this tool ships it will process your file, return the result, and keep nothing.

Questions

What happens to my file?

This tool is not built yet, so it does nothing with your file at all. When it ships it will follow the same rule as the rest of the site: process the file, return the result, keep nothing.

When will Split Word Documents be available?

There is no date. This format needs processing that is not available here yet, and rather than quietly producing a poor result the tool is switched off until it can be done properly. The rest of the toolkit is working and listed on the home page.

Do I need Microsoft Word installed?

No. The document is read directly from its underlying XML, so nothing needs to be installed and no licence is required. The result opens in Word, LibreOffice, Google Docs or Pages like any other document.

Is there a file size limit?

Uploads are capped at 32 MB. If your file is larger, split it first, or use one of the browser-side tools, which are bounded only by your device memory.

Working with DOCX

About DOCX

Word's Office Open XML format: a ZIP archive containing XML documents that describe the text, its styles and the relationships between parts. Content is stored as a flowing stream rather than fixed pages.

Because the text reflows, page breaks are decided at render time by whichever program opens it. Two applications can paginate the same file differently, so page counts are not a fixed property of the document.

Troubleshooting

  • Nothing happens after choosing a file. Check the file really is DOCX — a renamed extension fails here the same way it fails in other readers.
  • The upload is refused. Files over 32 MB are rejected. Split the document first, or use one of the browser-side tools, which are limited only by your device memory.
  • The result looks different from the original. Some conversions cannot carry every feature across formats. The page says what was dropped when that happens.
