Completely FREE Markdown converter with a live preview. No upload, no signup, nothing stored. Type or paste Markdown and watch it become clean HTML as you type — or flip the direction and turn existing HTML back into tidy, editable Markdown.
The output is plain, semantic HTML with no wrapper divs, no classes, and no styling baggage, ready to paste into a CMS, an email template, or a codebase. Conversion happens on every keystroke, locally.

Markdown in one paragraph
Markdown is the plain-text shorthand that half the internet writes in without knowing its name: # for a heading, asterisks for bold and italics, hyphens for bullet lists, brackets-and-parentheses for links. GitHub readmes, Reddit posts, Discord messages, note apps like Obsidian and Bear, and most developer documentation all speak it. Its whole point is that the source stays readable — but browsers and websites want HTML, and that gap is exactly what this converter crosses.
Markdown to HTML, with your eyes on the result
Paste your Markdown in the input box and two things update live: the generated HTML source, and a rendered preview of how it actually looks. The preview is the part most converters skip, and it is where you catch the missed blank line that glued two paragraphs together, the list that did not nest the way you pictured, or the link whose closing parenthesis went missing. The preview renders in an isolated frame, so nothing in it can interfere with the page.
Supported syntax covers what real documents use: all six heading levels, bold, italics, strikethrough, inline code and fenced code blocks, links, images, ordered and unordered lists, blockquotes, and horizontal rules. Line breaks inside a paragraph are preserved as breaks, which matches how most modern Markdown environments behave.
HTML to Markdown — the cleanup direction
The reverse direction earns its keep when you are migrating content: a blog moving to a static-site generator, documentation coming out of a legacy CMS, or a web page you want in your notes as something editable rather than a tangle of markup. Paste the HTML and the converter walks its structure, translating headings, emphasis, links, images, lists, quotes, code, and even simple tables into pipe syntax — while discarding scripts, styles, and attribute clutter. What comes out is the readable skeleton of the content, which is usually exactly what a migration wants.
Clean output is the feature
HTML generated from word processors and site builders is notoriously bloated — nested spans, inline styles, empty paragraphs. Markdown-generated HTML is the opposite: a heading is <h2>, a list is <ul>, and there is nothing else to strip. That makes this a practical laundering step, too: HTML in, Markdown out, Markdown back in, minimal HTML out. Writers use the same trick to move drafts between tools without dragging formatting debris along.
Local, instant, disposable
There is no convert button because there is no round trip — the parser is a few kilobytes of code running in your tab, so conversion is instantaneous and your drafts never leave your machine. Unpublished writing stays unpublished. Close the tab and both boxes are gone.
Frequently asked questions
How do I convert Markdown to HTML without installing anything?
Paste it into the input box on this page; the HTML appears immediately in the output box with a rendered preview beneath. Copy the output or download it as an .html file.
Why do my two lines keep merging into one paragraph?
Markdown treats a single newline as a soft break within the same paragraph and requires a blank line to start a new one. This converter preserves single newlines as visible line breaks, but for a genuinely separate paragraph, leave an empty line between blocks.
Will WordPress or platform-specific shortcodes convert?
Shortcodes, embeds, and platform extensions pass through as literal text — they are not Markdown or HTML, so no converter can translate them meaningfully. Convert the surrounding content, then re-add platform features in the destination system.
Important
This converter supports the core Markdown constructs — headings, emphasis, links, images, lists, quotes, code, and tables (HTML to Markdown). Exotic extensions from specific platforms may not round-trip perfectly, so review the output before publishing.
