Frequently Asked Questions
What Markdown features are supported?
The tool supports headings (H1-H6), bold, italic, strikethrough, inline code, fenced code blocks, links, images, blockquotes, unordered lists, ordered lists, tables, and horizontal rules.
What is the difference between Markdown and HTML?
Markdown is a lightweight markup language designed for readability. HTML is a markup language for structuring web content. Markdown is easier to write, while HTML provides more control over formatting and layout.
Should I wrap the output in an HTML document?
If you need a complete standalone HTML file (for email, embedding, or direct viewing), enable 'Wrap in HTML document'. This adds DOCTYPE, head, body tags and basic CSS styling.
Does this tool support GitHub-Flavored Markdown?
Yes. The tool supports GFM features including fenced code blocks with language hints, tables, and strikethrough syntax.
Can I use this tool to convert README files?
Yes. Paste your README.md content or open the file, and the tool will generate HTML that you can embed in web pages or documentation systems.
Why does my converted HTML look different from GitHub's Markdown preview?
That is expected. This tool outputs bare HTML structure with no styling; GitHub renders Markdown with its own CSS theme, so colors, fonts, and spacing differ. The content is the same. If you want standalone styling, enable 'Wrap in HTML document', which adds DOCTYPE, head, and body tags with basic CSS. For a GitHub-like look, paste the wrapped output into your own styled page or use a theme that mimics GitHub's styles.
Can I convert Markdown to HTML with Python or JavaScript libraries?
Yes. This page uses the marked library under the hood: in your own JavaScript project install marked (or remark) from npm and call the same parser. In Python, the 'markdown' library (markdown.markdown(text)) does the equivalent, and pandoc handles batch or complex conversions. This page is fastest for one-off jobs; libraries fit scripts, build pipelines, and apps.
Can I convert HTML back to Markdown?
Yes. Use our HTML to Markdown converter tool for the reverse conversion. Both tools are designed to work together.
What is the difference between inline code and code blocks?
Inline code (backticks) renders code within a paragraph: use `code`. Code blocks (triple backticks) render as a separate preformatted block, optionally with syntax highlighting for a specific language.
Does this tool handle nested lists?
Currently, the tool handles single-level lists. Nested lists may not render correctly. For complex Markdown, consider using a dedicated Markdown editor.
How do I add syntax highlighting to code blocks?
Specify the language after the opening backticks: ```javascript. The HTML output will include a class attribute (class='language-javascript') that syntax highlighters can use.
Why doesn't my table render after conversion?
GitHub-Flavored Markdown tables need three parts: a header row, a separator row of dashes (| --- | --- |), and at least one data row. Common mistakes that break the whole table: a missing separator row, mismatched column counts (every row must have the same number of pipes), or a pipe character inside a cell without escaping (use \| for a literal pipe). Fix the Markdown source and the table will convert.
Why does my markdown to html converter online output look unstyled?
The converter outputs raw HTML with semantic tags (h1, p, ul, table) and no CSS, so browsers apply their default stylesheet, which looks plain. Wrap the output in your page's stylesheet or add minimal inline styles; the HTML structure itself is correct. A markdown to html converter online never knows your design system, so styling is always your job.
Why can't I convert markdown to html online when my images are local files?
Local images have no URL the resulting HTML can reference; an HTML file opened on another device cannot see C:\pics\logo.png. Upload the images to a host, or use relative paths that point to files in the same folder as the HTML file. This is a limitation of HTML itself, not of the converter.
