Word to HTML With Images and Formatting Preserved — Full Guide
- Headings, bold, italic, lists, tables, and links all preserved as semantic HTML
- Images convert as embedded base64 data — works in browsers, replaceable later
- No inline styles — clean output that inherits your site CSS
- Underlines, strikethrough, and basic text formatting also preserved
Table of Contents
A Word document converted to HTML should preserve all the meaningful formatting: chapter headings become proper h-tags, bold and italic carry through as semantic tags, tables stay as tables, and images embed in the output. Here is a complete breakdown of what our converter preserves, what it intentionally strips, and what to do about the exceptions.
What Gets Preserved in the HTML Output
The conversion handles the following formatting elements accurately:
| Word Element | HTML Output |
|---|---|
| Heading 1 style | <h1> |
| Heading 2 style | <h2> |
| Heading 3–6 styles | <h3> through <h6> |
| Bold text | <strong> |
| Italic text | <em> |
| Underline text | <u> |
| Bullet list | <ul><li> |
| Numbered list | <ol><li> |
| Hyperlink | <a href="..."> |
| Table | <table><tr><td> |
| Image | <img src="data:..."> (base64) |
| Paragraph | <p> |
This covers the vast majority of formatting in real-world Word documents. A document with headings, body text, images, bullet points, and the occasional table will convert with its entire meaningful structure preserved.
How Images Are Handled
Images in Word documents are stored as binary data inside the .docx file. When converted to HTML, they embed as base64 data URIs:
<img src="data:image/png;base64,iVBORw0KGgo..." alt="">
This means the image is literally encoded as text inside your HTML file. The good news: it works in any browser, and the HTML file is self-contained — no external dependencies. The tradeoff: the HTML file gets large (a 100KB image becomes about 133KB of base64 text) and base64 images cannot be cached by browsers separately from the HTML.
For most conversion use cases — pasting into a CMS, sharing a document as a web page, publishing to Kindle — base64 images work fine. For production web pages where performance matters, the better approach is to extract the images and host them separately:
- Rename your .docx file to .zip and unzip it
- Find the images in the word/media/ folder
- Upload those to your web server or CDN
- Replace the base64 src values in the HTML with the hosted image URLs
This is extra work but produces properly optimized HTML for high-traffic pages.

Not everything from your Word document makes it to the HTML output — some things are intentionally removed:
- Font definitions: Font-family, font-size, and specific typeface choices are stripped. The HTML output inherits fonts from your website's CSS.
- Colors: Text colors and background colors from Word are not included in the HTML output. Clean HTML inherits color from your CSS.
- Line spacing: Specific line-height values are not preserved. Default browser spacing applies.
- Page margins and size: These are document-level properties that do not translate to web HTML.
- Headers and footers: Running headers and footers in Word do not convert to HTML — they are document structure elements that do not exist in web HTML.
- Comments: Word comments and track changes are not included in the output.
- Word-specific markup: Any mso- prefixed attributes, font metadata, and document properties are stripped.
The stripping of colors and fonts is a feature, not a bug, for web use. Your website has a CSS design system — you want HTML that inherits it, not HTML with hardcoded colors that clash with your design.
Edge Cases and Known Limitations
A few formatting elements do not convert perfectly:
Merged table cells: Cells with rowspan or colspan in Word may not convert with the merge preserved. The cell content will be there but the merge attributes may be lost. Check complex tables after conversion and add colspan/rowspan attributes manually if needed.
Custom paragraph styles: If your document uses custom styles (not the built-in Heading 1-6, Normal, etc.), those styles are not recognized and the content is treated as normal paragraphs. The safest approach is to use built-in Word styles for anything you want to map to a specific HTML tag.
Footnotes and endnotes: These may appear inline in the text rather than as separate reference sections. The content is preserved but the footnote formatting is simplified.
Math equations: Word's built-in equation editor uses OpenMath XML. The converter does not produce LaTeX or MathML output — equations may appear as text or be dropped depending on the equation complexity.
For standard business documents, reports, articles, and manuscripts, none of these limitations typically apply. They are edge cases in specialized document types.
Previewing the Output Before Using It
The converter includes a built-in Preview tab that renders the HTML in a light-background pane. This gives you a quick visual check before copying or downloading.
The preview uses browser defaults — no custom CSS — so it shows you the structural rendering without any site-specific styling. Headings will be larger and bolder than body text, lists will have bullets, tables will have borders. This is useful for confirming the structure converted correctly.
Before deploying the HTML to your actual website, test it in context — paste it into your CMS or site builder and preview it with your actual site CSS applied. The final rendering will look different from the preview pane because your CSS will take over, which is the intended behavior.
To try the conversion: drop your .docx, switch between the HTML Code and Preview tabs, and confirm everything looks right before using the output.

Open Free Word to HTMLFrequently Asked Questions
Will my Word document images look the same in the HTML output?
Yes — images convert as embedded data and render identically to how they appear in the original Word document. The visual appearance does not change, though you may want to add width or max-width CSS to control sizing on different screen widths.
Do tracked changes and comments get included in the HTML?
No. Tracked changes and comments are stripped from the output. Only the final document content is included. Accept or reject changes in Word before converting if you want to control which version is in the HTML.
My Word document has a table of contents — does that convert?
The visual text of a Word TOC converts as paragraph content, but the internal Word TOC fields (PAGEREF, TOC codes) do not translate. For HTML, you would want to replace the Word TOC with anchor links to headings in the HTML document.
Does it preserve text in text boxes and shapes?
Text inside Word text boxes and shapes may not convert reliably. Text in the main body flow converts correctly. For important content in text boxes, move it to the main document flow before converting.
