Feature Overview

Full CommonMark Support

Write with confidence using the full CommonMark markdown specification, with extra features for alerts, syntax highlighting, and custom styling.

Live Preview Renderer

Built-in, resizable HTML preview powered by Bootstrap and Highlight.js, letting you see styled or unstyled output in real time.

Customizable & Export-Ready

Switch between light and dark mode, toggle word-wrap, and export your markdown to clean HTML or Bootstrap-styled documents.

Configure Settings

Tip: Open settings via the icon in the app toolbar.

Customize to your style

Formatting

Toggle Automatic Indentation - When enabled, MKEditor will automatically indent your text when you press Enter, following the indentation level of the previous line. This is especially useful for lists, code blocks, and nested content.
Toggle Word-Wrapping - Automatically wraps long lines of text so they fit within the visible editor window without requiring horizontal scrolling. Ideal for distraction-free writing and smaller screen sizes.

Editing

Render Whitespace - Visually display spaces, tabs, and other whitespace characters directly in the editor. Useful for aligning code, spotting formatting issues, or maintaining strict markdown layouts.

Miscellaneous

Display Minimap - Shows a miniature overview of your document along the side of the editor. Quickly navigate large files by clicking or dragging within the minimap view.
Use System Theme - Automatically adapts MKEditor’s appearance to match your operating system’s theme (light or dark), overriding the manual theme setting.

Export Documents

Tip: Configure exports via the icon in the app toolbar.

Export your work instantly

HTML Export

Clean HTML – Export your markdown into simple, unstyled HTML that’s ready for integration into any website or project.
Styled HTML – Export with Bootstrap, Highlight.js, and other provider styles embedded, ensuring your content looks exactly as previewed.

PDF Export

Print to PDF – Generate a polished PDF of your markdown directly from MKEditor, preserving fonts, colors, and spacing.
Custom Settings – Apply background color, font size, and line spacing preferences to tailor your exported PDF to your needs.

Editor Shortcuts

Tip: View shortcuts via the icon in the app toolbar.

Powered by Web

MKEditor is also available as a fully-featured web application, allowing you to write, preview, and export markdown directly in your browser without installing the desktop app. The web version offers the same CommonMark support, live preview renderer, and export options as the Electron-based application.

This makes it ideal for quick edits, collaborative sessions, or working on devices where installing software isn’t possible. Simply visit the MKEditor web page to start writing instantly - no downloads, no setup, just open and go.
