The Todoal Markdown Previewer is a fast, interactive browser-based editor that renders GitHub Flavored Markdown (GFM) into clean, styled HTML in real time. Whether you are drafting open-source README.md files, technical documentation, blog posts, or project notes, this tool provides synchronized side-by-side editing and previewing with support for tables, task lists, code syntax blocks, blockquotes, and strikethrough text.
Full support for GFM extensions including formatted tables, task checkboxes (- [x]), autolinked URLs, and fenced code blocks.
Markdown parsing happens locally in your browser memory. Your drafts, private documentation, and technical notes are never sent to external servers or logged in databases.
Analyze your markdown copy by tracking word length with the Word Counter, checking character limits with the Character Counter, and estimating reading duration via the Reading Time Calculator.
For web previewing and markup tools, test HTML code with the HTML Previewer, format HTML with the HTML Formatter, inspect vector assets via the SVG Viewer, or manage your project tasks with the Checklist Maker. Access all utilities in the Developer Tools Suite.
