Convert Markdown text into clean HTML.
Was this tool useful?
Does this Markdown to HTML tool upload my content to any server?
No. All Markdown parsing, HTML generation, previewing, and file loading happen entirely inside your browser. Nothing is uploaded or stored externally.
Why am I seeing 'Please enter some Markdown to convert'?
This appears when the input is empty or contains only whitespace. Add valid Markdown before clicking Convert.
What formats can I load from file?
You can load .md, .markdown, .txt, or any text/markdown file. Unsupported file types are rejected to prevent decoding errors.
What does 'Enable GitHub-flavored Markdown' do?
It turns on GFM features such as tables, task lists, automatic links, and improved list handling, using Marked's GFM mode.
What does 'Treat line breaks as <br>' mean?
When enabled, single line breaks (Enter) in Markdown are converted into <br> tags in HTML. When disabled, line breaks follow standard Markdown behavior.
What is the 'Smart quotes' option?
Smart quotes automatically converts straight quotes into typographic quotes and applies smart punctuation rules for dashes and ellipses.
Why doesn’t the heading style option change the output?
Marked does not currently support converting ATX vs Setext heading styles differently. The option is included for consistency and may support custom preprocessing in future updates.
Is the HTML preview safe?
Yes. The preview runs inside a fully sandboxed iframe with no scripts or same-origin access. Only sanitized HTML is displayed.
Can I download the generated HTML?
Yes. Clicking Download .html saves a full HTML document (with <html> and <body> tags) containing your converted content.
