Preview Your Markdown Like a Pro
Writing Markdown is easy. Seeing how it actually looks before you ship it? That is where most tools fall short. Our Markdown Previewer is a free, browser-based editor that renders your content in real time as you type. Whether you are drafting a README, writing documentation or preparing a blog post, you get an instant, accurate preview without ever leaving the page.
Why You Need a Live Preview
Markdown is a plain-text formatting language designed to be readable and writable by humans. But there is always a gap between what you write and what the reader sees. A heading that looks right in your text editor might actually be broken because of a missing space. A list that seems fine could be rendering as a paragraph because of indentation issues.
A live preview eliminates guesswork. Every character you type is immediately rendered, so you catch formatting errors the moment they happen. No more committing a README and then realizing half your links are broken.
Full Markdown Support
We render all the standard Markdown elements you use every day:
| Element | Syntax | What You See |
|---|---|---|
| Headings | # to ###### | Six levels of visual hierarchy |
| Bold and Italic | bold and italic | Formatted emphasis |
| Links | text | Clickable links that open in a new tab |
| Code | Backticks and fenced blocks | Syntax-highlighted code |
| Blockquotes | > text | Styled callout blocks |
| Lists | - or 1. | Ordered and unordered, including nested |
| Tables | Pipe syntax | Clean, aligned tables |
| Task Lists | - [x] item | Visual checkboxes |
| Horizontal Rules | --- | Clean section dividers |
Everything is styled using our design system, so the preview looks like a polished, published document rather than generic browser output.
MDX Detection
MDX extends Markdown with JSX, allowing you to embed React components directly inside your content. Our tool automatically detects when your content contains MDX syntax like component tags or import statements and switches the file type badge accordingly.
Since executing arbitrary JSX in a browser preview would be impractical and unsafe, component tags are displayed as text. A subtle information banner lets you know this is happening so there are no surprises. The standard Markdown elements in your MDX file still render perfectly.
Built-In Writing Stats
The toolbar shows three live statistics that update on every keystroke:
Reading Time uses the standard rate of 200 words per minute to estimate how long your content will take to read. This is invaluable for bloggers and content creators who need to hit a target length.
Word Count tracks the total number of words in your document. Whether you are writing to a specific limit or just keeping an eye on length, this number is always visible.
Character Count shows the total characters including spaces. This is useful for platform limits like meta descriptions, social media posts or any context where character precision matters.
Import and Export
You can import any existing .md or .mdx file from your device with a single click. The file contents load directly into the editor and all stats update immediately. When you are done editing, the Export button downloads your work as a properly named file with the correct extension based on the detected content type.
Your Content Stays Private
Everything happens right in your browser. We never send your text to a server, we do not store it and there is no logging. Once you close the tab, your content is gone. This makes it completely safe for private documentation, internal notes and sensitive drafts.
