Markdown and HTML Tools

The formats text passes through on its way to a web page. Write and preview Markdown, turn an HTML page back into Markdown, wrap plain paragraphs in tags, make a clean URL slug from a title, and encode or decode the characters HTML reserves for itself.

Every Markdown & HTML tool

Markdown

The Markdown editor shows a live rendered preview beside what you type, following CommonMark with the GitHub extensions most people expect — tables, task lists, fenced code with language hints, strikethrough. The rendered HTML can be copied out, which makes it a quick way to produce a fragment for a CMS that does not speak Markdown itself. HTML to Markdown goes the other way: paste a page's source or a rich-text export and get clean Markdown back, with headings, lists, links, emphasis and tables preserved and presentational cruft dropped.

Plain text to HTML

Text to HTML takes prose with blank-line paragraph breaks and produces paragraph tags, converting single line breaks to <br> if you ask, linkifying URLs, and escaping anything that would otherwise be read as markup. It is the tool for turning a plain email or a document export into something that can be dropped into a page without hand-wrapping every paragraph.

Slugs

The slug generator turns a title into the lowercase, hyphenated, ASCII-only string used in URLs. It transliterates accented characters rather than deleting them, strips punctuation, collapses runs of separators and trims the result, with options for the separator and maximum length. The same rules apply consistently, which is what matters when slugs are generated in more than one place.

HTML entities

The entity encoder and decoder converts between characters and their HTML representations: &, <, ©, numeric references and the full named set. Encode when you need to show markup as text, or when a character will not survive a particular pipeline; decode when you have scraped or exported content full of ’ and want the real apostrophes back. The tool shows named and numeric forms side by side.

Where the processing happens

All of these run in your browser. Nothing you paste is uploaded, and there is no account or history; when you close the tab, it is gone.
