MD to XHTML Converter
Processing entirely on your device — large files may take a moment.
Markdown Document and Extensible HTML exist for different jobs: Markdown is the lightweight markup language used by GitHub, Notion and countless blogs: a few symbols turn plain text into headings, lists, links and code blocks. Convert XHTML to PDF or Markdown the same way as HTML — the converter reads the tags, not the doctype.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the MD format
Markdown (John Gruber, 2004) is plain text that renders into rich documents: `#` headings, `*` emphasis, lists, links, code fences. You can write it in any editor, read it as-is, diff it in git, and twenty years later it still opens — which is why GitHub, Stack Overflow, Notion, Obsidian and every static-site generator settled on it for prose.
Its one honest weakness is dialect fragmentation: tables, footnotes and task lists all started as extensions (GFM, MultiMarkdown, Pandoc), so a sophisticated document can render differently across tools. Core Markdown — headings, lists, links, code — is bulletproof everywhere.
+ Strengths
- ✓Future-proof plain text, renders anywhere
- ✓Perfect for version control and documentation
- ✓Low-friction: readable even unrendered
! Limitations
- −Extension dialects fragment advanced features
- −Complex layout and precise design are out of scope
About the XHTML format
HTML is the markup language of the web itself. A document is plain text decorated with tags that describe structure — headings, paragraphs, lists, links, tables, images — and browsers turn that structure into a rendered, styled page. It is both a format and a program target: CSS styles it and JavaScript makes it interactive.
As a document format, HTML's strength is universality: any device with a browser displays it, text stays selectable and searchable, and links make it navigable. Its weakness is that rendering depends on the surrounding CSS and viewport, so it is a flowing document, not a fixed-layout one — printing or archiving an HTML page is inherently an approximation.
+ Strengths
- ✓Displays on every device with a browser
- ✓Semantic structure: headings, links, tables, media
- ✓Text remains selectable, searchable and accessible
! Limitations
- −Final look depends on CSS and viewport
- −Not a fixed-layout or print format
- −Untrusted HTML must be sanitized before display
Why convert MD to XHTML?
Converting makes sense where the strengths of XHTML meet what MD cannot give you. Displays on every device with a browser Meanwhile Extension dialects fragment advanced features One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MD to XHTML converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MD to XHTML?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are formulas, styles or multiple sheets converted?
No — this conversion extracts the data itself into XHTML. Formulas are exported as their current values, styling is not carried over, and multi-sheet workbooks convert sheet by sheet. For full fidelity between spreadsheet formats, exchange within the same tool family.
How large can my MD file be?
Since everything runs locally in your browser, the real limit is your device memory rather than an upload cap. Files up to a few hundred megabytes are usually fine on a modern computer; extremely large ones simply take longer.
