Common Questions
Q: Where is Markdown commonly used?
Markdown is the standard format on platforms like GitHub, GitLab, Notion, Slack, and Discord. It is widely adopted for README files, technical documentation, wikis, and blog content.
Q: Is my content sent to a server?
No. All Markdown conversion is performed entirely in your browser. Your text never leaves your device, so you can safely work with confidential or sensitive material.
Q: How do I export my work?
Click the "Download HTML" button to save a complete HTML file that includes styling. You can open it in any browser or upload it to a web server directly.
Q: Does the tool support tables?
Yes. GitHub Flavored Markdown table syntax is fully supported. Use pipes (|) and hyphens (-) to define columns and alignment, and the preview will render a properly formatted table.
Q: Can I include images in my Markdown?
Yes. Use the syntax  to embed images. The preview will display the image if the URL is publicly accessible. Local file paths will not work in the browser preview.
Q: What is GitHub Flavored Markdown (GFM)?
GFM is an extension of standard Markdown used by GitHub. It adds features like task lists (- [x]), tables, strikethrough (~~text~~), and fenced code blocks with syntax highlighting.
Q: Why does my line break not appear in the preview?
In Markdown, a single line break is treated as a space. To create a new paragraph, leave a blank line between blocks of text. For a forced line break within a paragraph, add two spaces at the end of the line.
Q: Can I use HTML inside Markdown?
Yes, most Markdown renderers allow inline HTML. You can use tags like <details>, <summary>, or <kbd> for advanced formatting not covered by standard Markdown syntax.
