About the Markdown Previewer
Type Markdown on the left and watch it render to HTML live on the right. It supports the everyday building blocks: headings, bold and italic, inline code and fenced code blocks, unordered and ordered lists, blockquotes, horizontal rules, links and ordinary paragraphs. The preview refreshes as you type, so it doubles as a scratchpad for drafting a README, a comment or a forum post.
One behaviour is worth calling out because it is also a safety guarantee: the tool escapes all HTML before rendering, so any raw <script> or other HTML tags in your Markdown are shown as literal text rather than executed. Links are further restricted to http, https and mailto, so a javascript: link is stripped out entirely. The trade-off is that this is a previewer for common Markdown, not a full CommonMark or GitHub-Flavored-Markdown engine — there are no tables, footnotes or task-list checkboxes.
Because it runs entirely in your browser, your draft never leaves your device. To hand-escape a snippet for pasting into a page, see HTML encode, and to check the length of what you have written try the word counter.
Frequently asked questions
Can I mix raw HTML into my Markdown?
No — and that is deliberate. All HTML is escaped before rendering, so tags you type appear as plain text instead of taking effect. It keeps the preview safe, but it means HTML passthrough, which some Markdown flavours allow, will not work here.
Does it support tables, footnotes or task lists?
No. It renders a common subset of Markdown rather than the full CommonMark or GitHub-Flavored-Markdown specification, so tables, footnotes and task-list checkboxes are not converted. Everyday elements like headings, lists, code, quotes and links all work.
Is it safe to paste Markdown from an untrusted source?
Yes. Because every HTML tag is escaped and links are limited to http, https and mailto, embedded scripts and javascript links cannot run. A script tag in the input is shown as text, not executed.
Which Markdown features are supported?
Headings, bold, italic, inline code, fenced code blocks, unordered and ordered lists, blockquotes, horizontal rules, links and paragraphs. These cover the great majority of everyday Markdown writing.
Is my text uploaded anywhere?
No. The Markdown is converted to HTML entirely in your browser, so your draft is never sent to a server, logged or stored.
