Frequently Asked Questions (FAQ)
Does this tool require internet to process conversions?
No. Once the web page has fully loaded, the conversion engine runs entirely on your device's browser using JavaScript. You can safely disconnect from the internet and continue converting your Markdown documents.
Can I use this for GitHub README.md files?
Absolutely. Our parser supports standard core Markdown features which are fully compatible with GitHub's markdown rendering protocols, making it perfect for previewing your repository documentation before committing.
Are my uploaded files stored anywhere?
Never. The 'Import' function uses the modern HTML5 FileReader API to read the text directly in your browser window. No data is ever sent to, or saved on, external servers.
How does the Live Preview tab work?
The Live Preview tab takes the raw HTML generated by the parser and injects it into a secure, styled container. This allows you to visually audit your links, lists, and images to ensure they display exactly as intended before pushing the code to production.
