About Markdown Editor & Preview

Markdown Editor & Preview helps teams write clean Markdown with instant rendered preview, lightweight formatting controls, and export actions. It is ideal for README drafting, product documentation, knowledge-base articles, and internal notes. The editor supports GitHub-flavored Markdown basics and sanitizes preview output for safer rendering. Local autosave preserves your draft in browser storage, reducing accidental loss during long editing sessions. You can copy either source Markdown or rendered HTML, then export as .md or .html files for publishing workflows.

Key Features

  • Live Markdown Preview

    Rendered output updates instantly as you type, enabling fast iteration on formatting and structure.

  • Toolbar Insert Actions

    Quickly insert bold, italic, code, lists, and headings at the current cursor selection.

  • Autosave Recovery

    Draft content is stored locally and restored automatically after refresh when no shared payload is provided.

  • Fullscreen and Preview Modes

    Switch to focused writing via fullscreen or preview-only mode depending on task context.

  • Copy and Export Options

    Copy Markdown or HTML directly, and export to .md or .html files for external workflows.

  • Client-Side Sanitization

    Preview HTML is sanitized in browser to reduce unsafe markup rendering risk.
