Frequently asked questions
Will it preserve tables?+
Tables are kept since most modern CommonMark renderers support them.
What about emoji shortcodes?+
Shortcodes (`:smile:`) are GFM-specific. They're left as-is; remove with the Emoji Remover tool if needed.
Does it handle alerts (NOTE/TIP)?+
GitHub alerts use blockquote syntax with a leading marker. They convert to plain blockquotes in CommonMark.
