No. Everything runs in your browser - your file never leaves your device. How this is verifiable
Anyone wanting to publish or reuse the content of a Word document on the web otherwise fights the bloated HTML that Word itself exports: hundreds of inline styles, empty span elements, broken lists. This tool takes your .docx file and produces lean, semantic HTML - headings become h1 to h6, bold becomes strong, italics become em, bullet lists become ul and ol, tables become table. The result can go straight into a web page, a CMS or a Markdown workflow.
The conversion maps the structure, not the pixel-exact look: it translates the meaning of the Word styles (Heading 1, Quote, List Paragraph) into matching HTML elements. Embedded images are written directly into the HTML file as a data URI, so a single self-contained file results. The document gets a clean head with UTF-8 encoding and the file name as the title.
Everything runs entirely locally in the browser via the mammoth library - your document never leaves your device, which for contracts, applications or internal texts is the decisive point. Honestly framed: the structured running text including images and links is carried over. Complex Word layout quirks (text boxes, multi-column setting, headers and footers, exact fonts, spacing and colours) are deliberately not reproduced, because clean web HTML abstracts away from exactly those. So you get content instead of layout cruft.

Limitations: Converts .docx (Word) into a self-contained, semantic HTML file (headings, bold/italic, lists, tables, links; embedded images as data URI). Only .docx (not the old .doc). The structure is mapped via Word styles, not the pixel-exact layout (text boxes, columns, headers/footers, exact fonts/spacing are omitted). Invalid or corrupt files are rejected with a clear message.
No. The semantic structure (headings, lists, tables) is carried over, not the pixel-exact look with fonts, spacing and columns.
They are embedded directly into the HTML file as a data URI, so a single self-contained file results.
No, only the modern .docx format (Office Open XML). Open a .doc in Word first and save it as .docx.
Yes, it is lean semantic HTML without the flood of inline styles that Word itself exports.
No, the conversion happens entirely locally in the browser; the document never leaves your device.
