Frequently asked questions
What markdown syntax is supported?
The set that covers real documents: # through ###### headings, **bold**, *italic*, `inline code`, ``` fenced code blocks, [links](url), - and 1. lists, > blockquotes, and --- rules. Tables and footnotes — the exotic extensions — aren't included; for GitHub-flavored edge cases, GitHub's own preview is the final authority anyway.
Where does my draft go if I close the tab?
It's autosaved to this browser's local storage half a second after you stop typing, so it survives closes and restarts on this device. It doesn't sync anywhere — download the .md for anything worth keeping permanently.
What's the Copy HTML button for?
It copies the rendered HTML — headings, lists, and code blocks as proper tags — for pasting into a CMS, email editor, or anywhere that accepts HTML but not markdown. The styling classes are simple and easy to restyle or strip.
Is it safe to paste markdown from unknown sources?
Yes — the renderer escapes all HTML in the source before applying markdown transformations, so embedded tags display as text rather than executing. Links are restricted to http(s) URLs and open with noopener.
About this tool
The markdown editor pairs a writing pane with a live rendered preview covering the everyday markdown set: headings, bold and italic, inline code and fenced code blocks, links, ordered and unordered lists, blockquotes, and horizontal rules. Drafts autosave to your browser as you type, and the toolbar exports both the raw markdown file and the rendered HTML for pasting into a CMS. Rendering is escape-first — source HTML is neutralized before any transformation — so pasting untrusted content can't execute anything. It's the fast place to draft a README, write a formatted post, or finally learn what all those asterisks do.
Like most tools on UtilityBase, the markdown editor runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more text tools here.
