Documentation
MarkdownWizard is a Markdown editor and document converter that runs entirely in your browser. Write on the left, watch it render on the right, then download the result in the format the moment calls for. Nothing you type is ever uploaded.
Getting started
- Open the editor. It starts with a sample document so you can see what rendering looks like — select all and start typing to replace it.
- Type or paste Markdown into the left pane. The preview updates as you type.
- Give the document a name in the title box at the top. That name becomes the file name of anything you download.
- Choose Download and pick a format.
To work on a file you already have, use Open… and pick a .md,.markdown, .mdown, .txt, or .text file. It is read in your browser; it is not uploaded.
The editor
- Side-by-side panes. Markdown on the left, rendered preview on the right, with synchronized scrolling.
- Draggable divider. Drag it to resize the panes. It is also focusable — use the arrow keys to move it, and double-click to reset it to the middle.
- Formatting toolbar along the bottom: undo and redo; headings 1–3; bold, italic, strikethrough, and inline code; bulleted, numbered, and task lists; block quotes; links, images, tables, code blocks, and horizontal rules.
- Live counts of words and characters at the end of the toolbar.
- Light and dark themes — the ◐ button toggles, and your choice is remembered.
On a narrow screen the panes stack vertically instead of sitting side by side, and the toolbar scrolls horizontally.

Download formats
Every format is generated in your browser. Nothing is sent anywhere to be converted.
| Format | Best for |
|---|---|
PDF .pdf | Sharing or printing. A real vector PDF with selectable text, not an image. |
Word .docx | Word, Google Docs, and LibreOffice. Genuine OOXML, with images embedded. |
Word 97–2003 .doc | Older Word versions that will not open .docx. |
Word template .dot | Opening in Word as a document template. |
Rich Text .rtf | Nearly every word processor ever made. |
Plain text .txt | Formatting flattened to readable text. |
Web page .html | A self-contained styled page you can open in any browser. |
Markdown .md | The raw source, exactly as written. |
The same menu also offers Print…, which opens your system print dialog — choosing “Save as PDF” there renders through the browser's own engine, which is the best fidelity available if a generated PDF is not quite what you wanted. Copy rich textputs the formatted document on your clipboard for pasting straight into Gmail, Word, or Docs, andCopy HTML source copies the rendered markup.
Autosave
Your document autosaves to this browser as you type, so reloading the page does not lose your work. It is stored in the browser's local storage on your own device — never on a server — under keys beginning mdw:.
Two things to know. New empties the editor and the autosaved copy with it, which is why it asks first. And because the copy lives in one browser on one device, it does not follow you to another browser, another machine, or a private window — download anything you need to keep.
Working offline
The editor keeps working after the page has loaded, with no network connection. The one thing that needs a connection is a remote image referenced by your Markdown, which the preview fetches from wherever you pointed it.
Privacy
There is no server, no account, and no upload. What you type stays in the browser tab. ThePrivacy Policy sets out exactly what the hosted site does and does not see, including the single case in which using the editor causes a request to leave your device.
If something goes wrong
- An export does not look right. Fidelity varies by format and by the app you open it in. For a PDF that matches the preview most closely, use Download → Print… and choose "Save as PDF".
- Your document disappeared. Autosave is per-browser and per-device. Clearing site data, a private window, or a different browser all start empty.
- An image is missing from an export. Remote images must be reachable at export time in order to be embedded.
