FAQ

Frequently asked questions

Quick answers to common questions about the Markdown and HTML Converter.

What does the Markdown and HTML Converter do?

It renders Markdown as HTML with a live preview, or converts HTML markup back into Markdown.

Is the Markdown and HTML Converter free to use?

Yes. It's free, with no sign-up, no watermark and no limit on how many times you use it.

Is my input safe when I use this tool?

Yes. Your content is converted entirely on your own device. Small Markdown/HTML libraries load from this site the first time you use each direction, but your content itself is never uploaded.

Does it support GitHub-flavored Markdown features like tables?

It supports common Markdown syntax including headings, lists, links, code blocks and tables.

Will converting HTML to Markdown lose any formatting?

Markdown can't represent every possible HTML feature (like complex nested layouts or inline styles), so unusual HTML may simplify during conversion.

Can I see what the HTML will actually look like?

Yes. A live rendered preview appears below the result whenever you convert Markdown to HTML.

Can I use the Markdown and HTML Converter on my phone?

Yes. The page is fully responsive and works on mobile, tablet and desktop browsers alike.

Does the Markdown and HTML Converter have any limitations?

It's built for standard Markdown/HTML content; embedded scripts or highly custom HTML components aren't meaningfully convertible to Markdown.
