Markdown Previewer
Type markdown on the left and watch it render on the right, instantly. Headings, lists, tables, code blocks, links, blockquotes — the whole everyday syntax — with a Copy HTML button when you need the generated markup. Everything renders locally, and raw HTML is escaped so pasted content can't inject scripts.

About Markdown Previewer
Why preview markdown before publishing
Markdown is designed to be readable as plain text, but the gap between what you write and what renders still bites: a missing blank line glues a list to a paragraph, an unclosed backtick swallows half a sentence into code formatting, and table pipes are notoriously easy to misalign. Previewing catches these instantly instead of after you've posted a README, GitHub comment, or documentation page. The split-pane layout means you never leave the editor — the preview updates live with each keystroke.
What syntax is supported
The renderer covers the markdown you actually use daily: all six heading levels, bold, italic, and strikethrough, inline code and fenced code blocks, links and images, ordered and unordered lists with nesting, blockquotes, horizontal rules, and GitHub-style pipe tables with header rows. Line breaks within a paragraph are preserved, matching how GitHub renders comments. It's intentionally a clean, predictable core rather than an exhaustive spec implementation — the syntax that covers READMEs, issues, wikis, and notes.
Safe rendering and clean HTML output
Any raw HTML in your input is escaped before markdown processing, so a pasted <script> tag renders as visible text instead of executing — you can safely preview markdown from untrusted sources without XSS risk. Links in your markdown are also sanitized against javascript: URLs. When you're happy with the preview, Copy HTML puts the generated markup on your clipboard, ready for an email template, CMS field, or static page. As with all FluidConvert developer tools, rendering is 100% client-side: your drafts never leave the browser.

Frequently Asked Questions
Why isn't my list or heading rendering?
The usual culprit is a missing space or blank line. Headings need a space after the # characters, and lists render most reliably with a blank line separating them from the paragraph above. For nested list items, indent with two or more spaces. The live preview makes this quick to debug — fix the character and watch the rendering snap into place.
Can I use raw HTML inside my markdown?
No — and that's deliberate. All raw HTML is escaped before rendering, so tags appear as literal text rather than becoming part of the page. This guarantees that previewing markdown from any source is safe from script injection. If you need custom HTML in your final document, add it after exporting via the Copy HTML button.
How do I make a table?
Use GitHub's pipe syntax: a header row of cells separated by | characters, then a separator row of dashes like | --- | --- |, then one row per line of data. Columns don't need to align visually in your source — the renderer handles that. The sample document loaded in the editor includes a working table you can copy and adapt.
What does Copy HTML give me?
The exact HTML generated from your markdown — headings as h1-h6 tags, lists as ul and ol, tables with thead and tbody, code blocks in pre and code tags. It's unstyled, semantic markup you can drop into an email template, CMS rich-text field, or static site and style with your own CSS.
Is my writing stored anywhere?
No. Rendering happens entirely in your browser with client-side JavaScript — your text is never uploaded, saved, or logged. That means drafts of anything private, from internal docs to unpublished posts, stay on your machine. It also means the previewer keeps working offline once the page has loaded. Copy your work out before closing the tab.
