What DOCX Viewer does

Use DOCX Viewer when you need to open a DOCX or Word attachment online on a shared or lightweight device.

When to use it

  • Open a DOCX or Word attachment online on a shared or lightweight device.
  • Read document text before deciding whether to download or forward it.
  • Check headings, paragraphs, and basic structure in a DOCX file.

How to use it

  1. Choose the DOCX file.
  2. Wait for the browser preview to render.
  3. Search or scan the text and keep the original for final edits.

What to check

  • Complex Word layouts, comments, and tracked changes may require native Word.
  • Do not treat preview rendering as legal formatting proof.

Known limits

Troubleshooting
