Markdown to HTML & HTML to Markdown Converter

Pure Markdown doesn't natively support video embeds, but you have two clean options. Easiest: paste a Markdown image link to the video thumbnail, wrapped in a regular link to the video — clicking takes the user to YouTube. Most parsers also accept raw HTML inside Markdown, so an <iframe src="https://www.youtube.com/embed/VIDEO_ID"> block works in tools like GitHub README files, MkDocs, and Hugo. Some static-site generators have shortcodes ({{< youtube VIDEO_ID >}} in Hugo) that compile to a clean responsive embed. Our converter passes through HTML, so iframes carry over to the HTML output untouched.

Markdown image syntax is . The square brackets contain alt text for accessibility, and the parentheses contain the path — relative, absolute, or full URL. For example,  converts to <img src="images/taj.jpg" alt="Taj Mahal">. Want to set a title (tooltip)? . For sizing, plain Markdown doesn't support width or height, so drop in raw HTML when you need it: <img src="..." alt="..." width="600">. Our converter preserves both styles. Always write meaningful alt text — it helps screen readers, SEO, and broken-image fallback.

Our Markdown converter has a split-pane live preview — type on the left, see HTML render on the right, instantly. No save button, no refresh required. For local editing, VS Code with the built-in Markdown preview (Ctrl+Shift+V) is excellent. Apps like Typora and Obsidian render WYSIWYG-style. If you need to publish, GitHub renders .md files in the browser with live preview during edits. For Indian devs writing technical docs in Devanagari or Tamil, all these tools handle Unicode perfectly — just make sure your file is saved as UTF-8 and not Windows-1252.

Use a backslash before the character you want to render literally. The list of escapable characters: backslash, backtick, asterisk, underscore, curly braces, square brackets, parentheses, hash, plus, minus, dot, exclamation mark, and pipe. So \*not italic\* shows as *not italic* instead of becoming italic. For code-heavy content, wrap the whole snippet in backticks — anything inside is treated as literal text. For HTML entities (like & becoming &amp;), Markdown leaves those alone, so write &amp; if you need a literal ampersand in your output. Our converter follows the CommonMark spec for predictable escaping.

Footnotes aren't in core Markdown but are supported by GitHub Flavored Markdown, MultiMarkdown, and most modern parsers. The syntax: Here's some text with a footnote.[^1] [^1]: This is the footnote content. The [^1] becomes a superscript link in the output, and the [^1]: definition can sit anywhere in the document — the parser auto-numbers them. You can use named labels too: [^note-india] is more readable than numeric IDs in long documents. Our converter supports footnotes by default, rendering them as a numbered list at the bottom with backlinks.

The task list syntax is - [ ] for unchecked and - [x] for checked. The output is a <ul> of <li> elements containing <input type="checkbox" disabled> — disabled because Markdown is a static format. GitHub renders these as interactive checkboxes only inside issues and PRs. To make them clickable in your own site, post-process the HTML to remove the disabled attribute and add a small JavaScript handler. Our converter outputs the standard GFM-compatible HTML so it works everywhere — GitHub, MkDocs, Docusaurus, Hugo, and most other static site generators. Great for project READMEs and todo notes.

Markdown is strict about line breaks. A single newline gets ignored — paragraphs require a blank line between them. To force a <br> within the same paragraph, end the line with two trailing spaces (often called the "two-space rule") or a backslash. So a line ending in two spaces followed by another line becomes First line<br>Second line. GitHub Flavored Markdown is more lenient and converts single newlines to <br> automatically, which is why behaviour seems to vary between parsers. Our converter has a "GFM line breaks" toggle so you can pick whichever style your destination expects.
