Markdown to HTML

Markdown to HTML renders a Markdown (.md) source file into a standalone HTML document you can open in any browser, attach to documentation, or host on GitHub Pages or a static site.

Markdown is popular for README files, technical blogs, and note-taking apps. This tool gives you a quick preview or export without running a local build chain like Hugo or Jekyll. All parsing happens in your browser — your draft documentation never uploads to a server.

Input: .md or .markdown plain-text files using common Markdown syntax — headings (#), bold, italic, lists, links, images, fenced code blocks, and blockquotes.

Output: .html file with basic embedded CSS for readable typography (headings, code blocks, links). The HTML is a single self-contained file unless your Markdown references external image URLs.

Step 1: Write or export your Markdown file from your editor (VS Code, Typora, Obsidian export, etc.).

Step 2: Upload the .md file to this tool.

Step 3: Click Convert.

Step 4: Download the HTML and double-click to open in Chrome, Firefox, or Safari.

Step 5: If images are missing, ensure Markdown image syntax uses full https:// URLs — local paths are not bundled.

GitHub-Flavored Markdown extensions (tables, task lists, strikethrough, footnotes, math) may render partially or differently than on GitHub.com. Mermaid diagrams and raw HTML blocks inside Markdown may be stripped or escaped.

Very large Markdown files (novel-length) can be slow. The output CSS is generic — customize the HTML manually for brand styling.

Blog drafts: preview Markdown before pasting into WordPress or Ghost.

README files: render GitHub Markdown for stakeholder review.

Email newsletters: convert MD snippets to HTML fragments.

Document Converter never uploads your file for conversion. Processing uses JavaScript in your browser tab — the same security boundary as editing a document offline. Closing the tab clears the in-memory copy unless you saved the output.

We may load analytics or ads when you visit the site, but those requests do not include your document bytes. For HR records, medical forms, or unreleased designs, local conversion avoids the third-party upload step that cloud converters require.

Cloud tools like Smallpdf and iLovePDF receive your file via HTTP upload, process it on their servers, and return a download link. That model is convenient for public PDFs but adds privacy and compliance risk for sensitive content.

Document Converter runs pdf-lib, PDF.js, Mammoth, SheetJS, or Tesseract.js directly in your browser. Open DevTools → Network while converting: you should see no POST containing your file. You trade server-side CPU for device-side privacy — often the right choice for personal and workplace documents.
