No. All processing happens entirely in your browser using the marked.js library and DOMPurify for sanitization. Your content never leaves your device.
This editor supports standard Markdown including headings, bold, italic, links, images, code blocks (with language hints), blockquotes, ordered and unordered lists, horizontal rules, and tables.
Yes, inline HTML is supported within your Markdown content. However, all output is sanitized with DOMPurify to prevent XSS attacks, so script tags and event handlers will be stripped.
The HTML export wraps your rendered content in a complete HTML document with basic responsive styling (font, spacing, code block formatting) so it looks clean when opened in any browser.
There is no hard limit. Since everything runs client-side, very large documents may cause slight delays in the live preview on older devices. For most use cases, performance is instant.
