Frequently Asked Questions
What is Markdown?▼
Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write formatted text using plain text syntax that's easy to read and write. Markdown is widely used for documentation, README files, blog posts, comments, and more. It can be converted to HTML and other formats.
What Markdown features are supported?▼
This previewer supports all common Markdown syntax: headings (# to ######), bold (**), italic (*), strikethrough (~~), inline code (`), code blocks (```), links, images, unordered lists (-), ordered lists (1.), task lists ([ ] and [x]), blockquotes (>), horizontal rules (---), and tables using pipe syntax.
Can I use this for GitHub README files?▼
Yes! This previewer supports GitHub Flavored Markdown (GFM) features like tables, task lists, and fenced code blocks. However, some GitHub-specific features like @mentions, issue references (#123), and emoji shortcodes (:smile:) are not supported. For those, use GitHub's built-in preview.
Does this support syntax highlighting in code blocks?▼
Code blocks are displayed with monospace formatting and a distinct background, but full syntax highlighting (colored keywords, strings, etc.) is not included to keep the tool lightweight and fast. The language hint after ``` is preserved in the HTML output for use with external syntax highlighting libraries.
Is my content safe when using this tool?▼
Yes, completely safe. This Markdown previewer runs entirely in your browser using JavaScript. Your content is never sent to any server, stored, or logged. You can verify this by disconnecting from the internet—the tool will continue to work perfectly.
Can I embed the rendered HTML in my website?▼
Yes! Click "Copy HTML" to get the rendered HTML code. You can paste this into any HTML document. Note that you may need to add your own CSS styles to match your website's design, as the preview styles are specific to this tool.
