Markdown to HTML Converter
Convert a Markdown file to a standalone HTML file in your browser. Useful for publishing on the web, embedding in a CMS, sharing a styled preview, or just viewing your README in a browser without a markdown viewer installed. The HTML is self-contained — styles are inlined, double-click to view.
-
Sensitive documents stay private
Resumes, contracts, NDAs, notes you'd never paste into a chatbot — these are the documents most worth keeping off cloud converters. Everything here happens in your browser. The converted file goes straight to your downloads, then it's gone from memory.
-
MD → HTML done right
The output is a complete HTML5 document with embedded readable-article CSS (serif body, sans-serif headings, 720px reading column). Same look as our DOCX → HTML output for consistency. Strip the <style> block if you want fragment-only HTML for pasting into a CMS that applies its own styling.
-
No signup, no watermark, no email
You don't make an account, you don't enter an email, you don't see ads, and the output isn't watermarked. Free in the actual sense of the word — not "free for now, while we figure out a paywall."
Frequently asked questions
Does my file ever leave my device?
No. The conversion runs entirely in your browser. The file is read into memory, processed by a JavaScript library running in the same tab, and the result is delivered straight to your downloads. Open DevTools while you convert — you'll see zero network traffic carrying your file. This matters for anything sensitive: contracts, drafts, financial documents, personal notes.
Is there a file size limit?
No fixed limit. The real ceiling is your device's memory. Most text and PDF files are small enough that this is never a concern — multi-megabyte documents convert fine on phones. Very large files (hundreds of MB) may struggle on older or memory-constrained devices.
What about the original file?
Untouched. The converted file is a separate copy that lands in your downloads. Your original stays exactly where it was on disk.
Does this work on mobile?
Yes. Tap the drop zone to open your phone's file picker, choose a file from Files / Downloads / Drive / iCloud, hit Convert. The result downloads to your device's standard download location.
How is this different from online converter sites that ask for an email?
Those sites upload your file to their servers, run conversion server-side, and email you a download link. They get to read your document, log your IP, and store the file (for some period). This tool does none of that — everything runs in your browser tab. We don't even have an account system, so there's nothing to sign up for and nothing to log out of.
How can I use the HTML in WordPress / Substack / Ghost?
Most CMSs want just the body content, not a full HTML document. Open the downloaded .html in a text editor, copy everything between <body> and </body>, paste that into your CMS's HTML/code view. The inline CSS in the <head> only matters for standalone viewing — your CMS applies its own theme.
What's the styled output look like?
Clean readable defaults: Georgia at 18px with 1.7 line-height for body text, a system sans-serif for headings, monospace blocks for code with light gray backgrounds, blockquotes with left borders. The look is intentionally generic — easy to override with your own CSS if you're integrating into a site with established styling, or pleasant to read as-is if you just want a quick preview.
Which Markdown flavor does this support?
GitHub-Flavored Markdown (GFM) — covers CommonMark plus tables, task lists, strikethrough, autolinks, and fenced code blocks. If your markdown renders correctly on GitHub, it renders correctly here.
Are code blocks syntax-highlighted?
Not in v1. Code blocks render in monospace with preserved newlines and a light background, but no token highlighting. If you need syntax highlighting on the final page, add a library like Prism or highlight.js to your CSS / JS stack after the conversion.
What about images?
Image references in your markdown are preserved as <img> tags pointing to the URLs you wrote. If your markdown uses relative paths (./image.png), those paths will be relative to wherever you host the HTML. If you use absolute URLs, the images load from those URLs when someone opens the HTML.
Does the HTML pass accessibility checks?
It uses semantic HTML5 elements (h1-h6, ul/ol, blockquote, etc.), which is the foundation of accessibility. Tables generated from GFM markdown include proper <th> headers. There's no skip-link, ARIA landmarks, or alt-text inference for images (alt text is whatever you wrote in the  syntax). For full WCAG compliance, you'll want to add a few things by hand.
