How this works in your browser
A lightweight parser running in your browser converts the common Markdown constructs into HTML: heading levels from leading hashes, emphasis from asterisks and underscores, list items from line-leading markers, links from the bracket and parenthesis pattern, and inline code from backticks. The scope is deliberately the widely-agreed core rather than any one platform's extended dialect, since Markdown has no single specification and every major site implements its own additions. That is also the honest reason tables and image embeds are absent: they belong to extensions rather than to the common syntax, and rendering them one way here would not guarantee the same result where you publish.

Frequently asked questions
What it can and cannot do, and what happens to your files.
What Markdown syntax is supported?
Headings, bold, italic, inline code, bullet lists, and links.
Is my Markdown uploaded anywhere?
No, rendering happens entirely in your browser using a lightweight built-in parser.
Does it support tables or images?
This version covers the most common Markdown elements; tables and image embeds are not rendered in this simplified previewer.
Why does my Markdown render differently on GitHub?
Because there is no single Markdown standard. GitHub, GitLab, Reddit and most static site generators each extend the original syntax differently, adding tables, task lists, footnotes and their own quirks. Anything beyond the common core is worth checking in the destination itself before publishing.
Why is my list not rendering?
Usually a missing blank line before it. Most parsers require an empty line between a paragraph and the list that follows, otherwise the list markers are read as part of the paragraph text. Inconsistent indentation on nested items is the other frequent cause.
Why use Markdown rather than a word processor?
Because it stays readable as plain text, works in version control where changes show line by line, and converts cleanly to HTML and other formats. The trade is limited formatting control, which is precisely why it suits documentation and writing rather than layout.
Is my Markdown uploaded anywhere?
No. Parsing and rendering both happen in your browser, so unpublished documentation stays on your device.
