What is MD Diff?
A diff viewer for Markdown documents. Compare two versions and toggle between diffing the raw source and the rendered output.
How it works
Text is diffed with jsdiff and rendered inline; a toggle switches between raw Markdown and its rendered form.
- Enter your input. Type or paste your input into the field above — the tool responds instantly.
- Review the result. Output updates live as you type. Everything runs entirely in your browser.
- Copy or download. Use the Copy button to grab the result, or Download to save it as a file.
Examples
Reviewing doc changes
Paste two versions of a Markdown file and see additions, deletions, and changes highlighted side by side.
Common mistakes
Whitespace-only noise
Line-ending or trailing-space changes flood the diff — a whitespace-ignore toggle filters them out.
