Markdown Previewer
The Markdown Previewer renders Markdown side-by-side as you type. The left pane is an editable source textarea; the right pane shows the formatted HTML output updated instantly. Supports the most common Markdown constructs: ATX headings (#, ##, ###), bold (**), italic (*), strikethrough (~~), inline code, block code fences, links, images, unordered lists, blockquotes, and basic paragraph breaks. Pure client-side — no server roundtrip, no data leaves the browser — perfect for drafting documentation, blog posts, and README snippets quickly.
How to Use
To use the Markdown Previewer, simply open the tool page and interact with the controls in the panel above. The interactive panel handles input and produces instant results entirely in your browser — no signup, no upload. Use the Copy button when you want to transfer the output to your clipboard.

Frequently Asked Questions
Is full GFM supported?
This is a lightweight subset covering the most common syntax. Tables and strikethrough work; footnotes and task lists need a more heavyweight parser.
Can I export the HTML?
Yes. Use the browser source-view or copy the rendered output directly.
Can I save my Markdown?
Auto-save to localStorage is not yet built. You can copy the source from the editor textarea.
Does it support code highlighting?
Only basic block styling. Syntax highlighting would require an additional library.
Is my data uploaded?
No. All Markdown rendering happens locally in your browser.
