Convert Word to clean HTML without uploading your document
Wordâs own HTML export often contains nested spans, inline styles, and proprietary mso- attributes that are difficult to maintain. This page uses mammoth to produce semantic HTML from the documentâs styles. Headings, paragraphs, lists, emphasis, and links become the corresponding HTML elements instead of copies of Wordâs presentation markup. The result is suitable for a CMS or source repository, and the document never leaves your device.
How it works
- Drop your .docx files below.
- Document styles are mapped to semantic HTML tags.
- Download clean .html files. No Word cruft.
Frequently asked questions
How is this better than Wordâs own âSave as HTMLâ?
Wordâs HTML export contains many inline styles and proprietary attributes. mammoth instead maps semantic document styles to clean tags: headings to <h1> through <h6>, lists to <ul> or <ol>, and emphasis to <strong> or <em>.
Will it carry over every bit of formatting?
Deliberately not. It preserves structure and semantic emphasis, not exact fonts, colors, or spacing. That is what keeps the output clean. If your document relies on precise visual styling, you will add CSS afterwards; if it is well-structured prose, the HTML is ready to use.
Is my document uploaded to convert it?
No. mammoth runs in your browser and reads the .docx locally. Nothing is transmitted, and it works offline once loaded.
What happens to images?
Images are embedded inline in the HTML as data URIs, so the single .html file is self-contained. For a website you will often want to extract them into separate image files, but the conversion loses nothing.
