Frequently Asked Questions
What file types are supported?
The tool supports HTML (.html, .htm), Markdown (.md, .markdown), and plain text (.txt) files.
Is my data secure?
Yes! All processing happens entirely in your browser. Your documents are never uploaded to any server.
Can I choose the page size?
Yes, you can select from A4, Letter, or Legal page sizes, and toggle between Portrait and Landscape orientations.
How does Markdown rendering work?
