Local md->HTML

Material Loss Calculator

Q: "Does this match GitHub exactly?"

"Exact parity is difficult, so we clearly state the supported scope (partial GFM). GitHub-specific extensions and CSS differences can change the look."

Q: "Does it support math or Mermaid?"

"Not in the initial release. If demand is high, we can add it as an optional feature later."

Q: "Is my input saved?"

"No. Conversion happens locally in your browser and the content is never sent to a server."

Q: "Can I paste the HTML into my blog?"

"Usually yes, but some platforms restrict HTML. Please follow the rules of your target service."

Поширені запитання

Does this match GitHub exactly?

Exact parity is difficult, so we clearly state the supported scope (partial GFM). GitHub-specific extensions and CSS differences can change the look.

Does it support math or Mermaid?

Not in the initial release. If demand is high, we can add it as an optional feature later.

Is my input saved?

No. Conversion happens locally in your browser and the content is never sent to a server.

Can I paste the HTML into my blog?

Usually yes, but some platforms restrict HTML. Please follow the rules of your target service.
