High-Performance Client-Side WebAssembly Engine

BoxyKit Markdown Studio utilizes an optimized WebAssembly parser and CSS inlining engine. Your articles, confidential documentation, and drafts are processed entirely in browser memory. Nothing is ever uploaded to external servers, providing instantaneous rendering speed and ironclad privacy even in offline environments.

Frequently Asked Questions

Q: Does BoxyKit Markdown Studio upload my documents to any server?

No. All parsing, rendering, syntax highlighting, and file conversions occur entirely inside your browser's WebAssembly sandbox. Your text, drafts, and proprietary documentation never touch any external server.

Q: How does the WeChat Official Account and Zhihu one-click copy work?

Standard Markdown HTML loses styles when pasted into rich text editors like WeChat and Zhihu. BoxyKit uses a dedicated WASM engine to inline every CSS style directly onto each HTML tag, preserving colors, font sizes, borders, and code blocks flawlessly upon pasting.

Q: Can I convert between Markdown, HTML, and Word (DOCX)?

Yes. BoxyKit includes built-in two-way converters: HTML to clean Markdown, Markdown to Microsoft Word (.docx), and Markdown to standalone styled HTML or PDF. All conversions are executed locally on your device.

Q: What is Pangu spacing and how does it improve typography?

Pangu spacing automatically inserts standardized typographic half-width spaces between Chinese characters and English letters or numerals (e.g., 'BoxyKit 工具箱' instead of 'BoxyKit工具箱'). It automatically skips code blocks and URLs to ensure clean, professional formatting.

Q: Can I edit and align complex Markdown tables easily?

Yes. The built-in table tool allows you to paste raw CSV, TSV, or Excel spreadsheet data to immediately generate properly aligned, pretty-printed Markdown tables with customizable column alignments.

Q: Does BoxyKit Markdown Studio work offline?

Yes. Once the page is loaded, the WebAssembly binaries and assets run completely offline. You can draft, edit, and export documents even without an active internet connection.
