Client-side converter for a practical Markdown subset: ATX headings, lists, emphasis, links, inline code, and fenced code blocks. Output is meant for drafts; sanitize before rendering untrusted Markdown on a site.
Quick answer: Markdown to HTML (Core Syntax)
Markdown→HTML: convert a practical subset (headings, lists, emphasis, links, fenced code) to escaped HTML suitable for preview pipelines.
Example: A README with H1, bullet list, and ```js fence becomes semantic HTML with escaped code innards.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Authoring tools still need a sanitizer before rendering user Markdown on the public web - this page returns string output you can paste into CMS previews or tests.

Click a question to expand the answer.
No; tables, footnotes, and GitHub-only extensions may not render; use a full processor for those.
Run through your platform sanitizer; Markdown can include raw HTML in advanced cases.
Yes; triple backtick fences map to <pre><code> with basic escaping inside.
Use a dedicated round-trip tool; this page is Markdown → HTML only.
Very large documents may be slow in-browser; split chapters when possible.

GitHub tables and footnotes are intentionally out of scope for this lightweight build. Raw HTML inside Markdown is discouraged; treat unknown input as hostile until cleaned. Very large files may feel sluggish - split chapters for iterative editing.
