About this tool
DOCX to HTML converts Word document structure into clean web HTML locally in the browser with Mammoth.js. The generated preview is sanitized before display.
Frequently asked questions
Is my Word document uploaded?
No. The DOCX file is read and converted locally in your browser.
Will the HTML look exactly like Microsoft Word?
No. This mode prioritizes clean semantic HTML. Headings, paragraphs, lists, links, tables, footnotes and many embedded images usually convert well, while advanced Word layout features can differ.
Why is the preview sanitized?
DOCX is an input format that can contain links and complex content. Toolardo sanitizes generated HTML before placing it in the preview to reduce script and markup injection risk.
