Frequently Asked Questions

Here are the answers to the most frequently asked questions. If your question isn't listed, or you need more info, or have feedback, please reach out to us.

What is Markdown?
Markdown is a lightweight markup language that makes it easier to write and format text for the web. It uses simple syntax like asterisks for bold text and hashes for headings, which gets converted to proper HTML. It was created to be easy to write and read in its raw form, while still being convertible to HTML.
Why would I need to convert Markdown to HTML?
Many content management systems, blogging platforms, and documentation sites accept HTML but not raw Markdown. By converting your Markdown to HTML, you can write content in the simpler Markdown format, then paste the resulting HTML where needed. It's also useful for email templates, static websites, or anywhere else HTML is required.
Does this tool support GitHub Flavored Markdown?
Yes, this converter supports GitHub Flavored Markdown (GFM), which includes features like tables, task lists, strikethrough text, and syntax highlighting for code blocks. These elements will be properly converted to their HTML equivalents.
What's the difference between Default and Sanitized HTML options?
The Default option converts your Markdown directly to HTML without modification. The Sanitized option removes potentially dangerous HTML (like scripts or event handlers) that might be included in your Markdown. Use Sanitized if you're concerned about security, especially if the content comes from an untrusted source.
Is my Markdown data sent to a server?
No, this tool processes everything locally in your browser. Your Markdown content is never sent to any server, making it safe for sensitive or private content. The conversion happens entirely using JavaScript running on your device.
Can I use this for blog posts or CMS content?
Absolutely. Many bloggers and content creators write in Markdown for its simplicity, then convert to HTML when posting to platforms like WordPress, Medium, or other CMS systems that don't natively support Markdown. Tool23 makes this workflow hopefully a bit easier.
