Questions

Does Markdown to HTML upload my Markdown?

No. Markdown is parsed and converted locally in your browser tab.

Does it allow unsafe HTML?

No. Raw HTML is escaped and the converter emits a safe HTML subset for common Markdown syntax.

Can I download the converted HTML?

Yes. The shared Markdown engine can copy an HTML fragment or download a standalone HTML file.

Does Utilumo upload my input?

No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.

Do I need an account?

No. Utilumo tools are built to work without accounts or sign-in.
