Markdown Preview
Write Markdown and see the rendered HTML preview in real time with syntax highlighting.
Discord and Slack Markdown — what works where
Discord and Slack each support a subset of Markdown, with some differences. Quick reference:
| Syntax | Discord | Slack | GitHub/GFM |
|---|---|---|---|
**bold** | ✅ | ✅ | ✅ |
*italic* | ✅ (*italic* or _italic_) | ✅ (_italic_ only) | ✅ |
~~strike~~ | ✅ | ✅ (~strike~ — single tilde) | ✅ |
__underline__ | ✅ | ❌ | ❌ |
`code` | ✅ | ✅ | ✅ |
```code block``` | ✅ (with syntax highlighting) | ✅ | ✅ |
> quote | ✅ | ✅ | ✅ |
>>> multiline quote | ✅ (until message end) | ❌ | ❌ |
||spoiler|| | ✅ | ❌ | ❌ |
# heading | ✅ (since 2023) | ❌ | ✅ |
[text](url) | ❌ (raw URLs only) | ✅ (via <url|text>) | ✅ |
| Tables | ❌ | ❌ | ✅ |
Our preview uses GitHub Flavored Markdown — the most complete variant. Content that renders here will generally work on GitHub, GitLab, Bitbucket, Hugo, MkDocs, and static site generators. For Discord/Slack-specific formatting, test in the target app directly.
GitHub Flavored Markdown — what you can do
Our renderer implements GitHub Flavored Markdown (GFM), the dialect used by GitHub issues, pull requests, README files, and most modern static site generators (Hugo, Jekyll, Next.js MDX, Astro, VitePress).
| Syntax | Renders as |
|---|---|
# H1, ## H2, ..., ###### H6 | Headings |
**bold**, *italic*, ~~strike~~ | Emphasis |
`inline code` | Inline code span |
```language | Fenced code block with syntax highlighting |
- item / 1. item | Unordered / ordered list |
- [x] done / - [ ] todo | Task list |
[text](url),  | Link, image |
> quoted | Blockquote |
| a | b | | Table |
--- | Horizontal rule |
https://example.com | Auto-linked URL |
:smile: | Emoji shortcode → 😄 |
What GFM doesn't include: math ($\LaTeX$), mermaid diagrams, footnotes — those are platform-specific extensions.
Frequently Asked Questions
How do I preview Markdown online?
Paste any Markdown text into the left panel. The right panel renders the output in real time — headings, bold, italic, links, code blocks, lists, tables, task lists and images. Perfect for previewing README files, blog posts or GitHub issues.
Does this markdown renderer support GitHub Flavored Markdown (GFM)?
Yes. Full GFM support: fenced code blocks with syntax highlighting, tables, strikethrough, task lists (`- [x]`), auto-linking, footnotes, and emoji shortcodes (`:smile:` → 😄). Same renderer used by GitHub.
Can I export my Markdown preview to HTML or PDF?
Yes. Copy rendered HTML from the right panel with one click, or use browser Print → Save as PDF. Syntax highlighting and styling carry over. No server upload needed.
Is my Markdown content private?
Yes — entirely client-side. Your content never leaves the browser. Safe for drafting internal docs, RFCs, pull request descriptions or private notes.
How is this different from typing Markdown on GitHub or Notion?
This is a standalone preview — no auth, no workspace, no formatting surprises. Useful when you want to draft and preview Markdown before committing it to a README, wiki, or static site generator like Hugo, Jekyll or MkDocs.
