Why use Parsy for Markdown preview?

GitHub renders Markdown beautifully — but your local .md files and drafts don't get that treatment until you commit them. Parsy acts as a local Markdown preview tool that renders .md content with GitHub-flavored styling directly in your browser tab.

Headings, lists, tables, and fenced code blocks render exactly as you'd expect, so you can proofread a README or a draft post without pushing it anywhere first.

Frequently asked questions

Does Parsy support GitHub-Flavored Markdown tables and code blocks?

Yes. Tables and fenced code blocks render with the same visual style you'd see on GitHub.

Can I preview a local .md file?

Yes. Open the Parsy web app or the extension's File Viewer and drag your .md file in, or use 'Browse Files' to select it.

Is my Markdown content uploaded anywhere?

No. Rendering happens 100% locally in your browser — nothing is sent to a server.

Does Parsy support Markdown checklists and strikethrough?

Parsy focuses on core GitHub-flavored Markdown: headings, lists, tables, links, and fenced code blocks. Some extended GFM syntax may render as plain text.

Can I copy the rendered content?

Yes. Click to copy sections of the rendered preview while you work.
