FAQ（6）
Is Markdown rendered on a server?
No. Conversion uses a self-hosted Markdown engine in your browser. LocalKit processes this in your browser on www.908885.com—input is not uploaded to our servers for computation.
Which Markdown features are supported?
Headings, lists, links, images, code blocks, bold/italic, blockquotes and hr—the common subset. Not every GitHub Flavored Markdown extension is guaranteed.
Can I convert HTML back to Markdown?
Yes. Choose HTML → MD when available. Complex layouts, tables, or inline styles may simplify during conversion.
Do templates leave my device?
No. Templates are static strings bundled with the page and processed locally like any other input. LocalKit processes this in your browser on www.908885.com—input is not uploaded to our servers for computation.
Will scripts in HTML run?
Conversion reads text via DOMParser-style paths; this tool is not an HTML sandbox for executing arbitrary pages. Treat untrusted HTML carefully.
