Markdown to HTML Converter

WHAT IT DOES Markdown to HTML Converter transforms any Markdown text into clean, standards-compliant HTML instantly. The extension supports headings (H1-H6), bold and italic emphasis, links with titles, images with alt text, fenced and indented code blocks with syntax highlighting hints, nested blockquotes, unordered and ordered lists (including nested and task lists), horizontal rules, tables with alignment, strikethrough, and autolinks. A live side-by-side view shows the raw Markdown on the left and the rendered HTML on the right, updating with every keystroke. The "Copy HTML" button places the complete, formatted HTML output onto your clipboard in a single click. WHERE IT RUNS The extension executes entirely within your browser's local JavaScript environment. No Markdown content, HTML output, or any user data ever leaves your machine. There are no external API calls, no telemetry, no analytics, and no background servers. All parsing and rendering happens using a pure WebAssembly-compiled parser that runs with native speed inside the extension's isolated sandbox. The tool works in all Chromium-based browsers and integrates with the BotGentz extension framework. HOW TO USE Click the extension toolbar icon to open the converter panel. Type or paste Markdown into the left text editor area. Watch the right panel update with the rendered HTML in real time. Use the "Copy HTML" button to copy the output to your clipboard. The panel remembers your last Markdown input across browser sessions. Close the panel with the Escape key or by clicking the toolbar icon again. THE TOKEN-STREAM RENDERER — WHY IT WORKS Where most Markdown converters use fragile regular expressions that break on nested syntax or corner cases, this extension employs a two-phase streaming pipeline. Phase one lexes the input character-by-character into a token stream, identifying Markdown constructs using a finite-state machine with 47 distinct states that track context—whether inside a code block, a list, a blockquote, or an emphasis span. Phase two feeds this token stream through a stack-based renderer that maintains an explicit nesting context. Each token triggers specific stack operations: pushing new HTML tags, popping when contexts close, or emitting text with proper escaping. This design guarantees that every opening tag has a matching closing tag, that nesting order is preserved (e.g., bold inside italic produces `` not the reverse), and that user content is always HTML-escaped to prevent injection. The renderer also optimizes output by collapsing whitespace where semantically appropriate while preserving significant whitespace inside code blocks and preformatted text. THE PANEL The converter panel is fully draggable by its title bar and remembers its position per site and per browser window. It snaps to the edges of your screen for neat alignment when dragged near borders. Collapse the panel to a small icon strip using the minimize button, restoring it with a single click. Resize the panel by dragging any edge or corner; the Markdown and HTML views adjust proportionally. Press the Escape key to close the panel immediately. The panel maintains independent state for each browser tab, so you can convert different Markdown content in different tabs simultaneously. PLEASE NOTE This extension requires the free BotGentz extension framework to be installed and enabled for proper operation. Web platforms and Markdown specifications evolve over time; while the parser is thoroughly tested against the CommonMark 0.31.2 test suite, future syntax extensions may require updates. All user Markdown content and generated HTML are stored locally in your browser's storage and are never transmitted, logged, or shared. The extension requests no network permissions and functions entirely offline.
