A deliberately safe Markdown subset
The renderer supports headings, paragraphs, unordered and ordered lists, blockquotes, fenced code blocks, bold text, emphasis, inline code, and links. Raw HTML is displayed as text rather than inserted into the page, which prevents pasted script or iframe markup from executing.
Live preview stays on your device
Input is processed in the current browser tab. Gypes does not intentionally transmit the Markdown to a server. The preview updates as you type and can be inspected alongside the source, making it useful for short notes, README sections, documentation drafts, and formatted messages.
Markdown has multiple dialects
CommonMark, GitHub Flavored Markdown, documentation systems, and publishing platforms differ in tables, task lists, footnotes, heading identifiers, automatic links, line breaks, and embedded HTML. This compact renderer does not claim full compatibility with any external dialect.
Check links and code before publishing
Only web and mail links are made clickable. A rendered preview cannot verify that a destination is safe, current, or correct. Code blocks are displayed as text and are never executed, but copied code should still be reviewed in its actual environment.
Use a source-to-destination check
Draft one small section containing a heading, a paragraph, a list, a link, inline code, and a fenced code block. Compare every part of the preview with the source, then paste the same Markdown into the intended publishing system. Check whether that system changes line breaks, heading levels, list numbering, link targets, or code indentation. This separates an error in the source from a difference between Markdown dialects.
Keep the plain-text Markdown as the editable original. Copying rendered text back from a browser can discard markers and structure. When content came from someone else, inspect the literal link destination before following it and review any code as untrusted text. A safe preview prevents raw HTML execution here, but it cannot establish that linked pages or pasted commands are safe.
This tool is intended for previewing a documented subset, not for exact round-trip conversion or security validation of Markdown from untrusted authors. Confirm output in the final publishing platform.
