FAQ
Can Markdown Diff compare README files?
Yes. Paste any Markdown content — README files, changelogs, documentation pages, or blog posts — and the diff will highlight every change.
Is my Markdown content sent to a server?
No. All comparison logic runs entirely in your browser. Your content never leaves your device.
Does Markdown Diff support GFM (GitHub Flavored Markdown)?
Yes. The tool compares Markdown as plain text, so it works with any Markdown variant including GFM tables, task lists, and code fences.
