Frequently asked questions
Is my content sent to a server?
No. Rendering happens entirely in your browser. Nothing you type is uploaded or processed remotely.
Does the renderer execute HTML in my input?
No. The renderer escapes all HTML in your source before processing, so pasting content with HTML tags will display them as literal text rather than executing them.
What Markdown features are supported?
Headings (h1–h6), bold, italic, strikethrough, inline code, fenced code blocks, blockquotes, ordered and unordered lists, links, images, and horizontal rules.
