How to convert MARKDOWN to HTML
Markdown is a lightweight markup language designed to be readable as plain text while also converting cleanly to HTML. It is the standard format for README files on GitHub, documentation in static site generators like Jekyll and Hugo, and content in tools like Notion and Obsidian. When you need to publish Markdown on a platform that requires HTML, or embed it in a web application, you need to convert it first.
BoltConverter converts Markdown to HTML on its servers, supporting standard CommonMark syntax plus GitHub Flavored Markdown extensions including tables, strikethrough, task lists, and fenced code blocks with syntax hints.

Frequently asked questions
Which Markdown flavors are supported?
The converter supports CommonMark as the base standard, plus GitHub Flavored Markdown (GFM) extensions: tables, strikethrough text, task list checkboxes, and fenced code blocks.
Does the output include a full HTML document or just the body?
The output is the HTML fragment for the body content, without a full document wrapper (no html, head, or body tags). This is suitable for embedding in an existing page. If you need a complete standalone document, wrap the output in your own HTML template.
Are code blocks syntax highlighted?
Code blocks are wrapped in pre and code tags with an appropriate language class (e.g., language-python). You can apply syntax highlighting in your browser by adding a library like Prism or highlight.js to your page.
What happens to inline HTML in the Markdown?
Inline HTML in the Markdown file is passed through as-is to the output. This is standard CommonMark behavior.
Is my content kept private?
Your Markdown is sent over HTTPS and deleted from the server after conversion. BoltConverter does not store your content.
