排版还原与公文字体小贴士
本工具已默认内置开源中文字体库（支持常见简体中文、繁体中文、日韩汉字）。如果您的文档包含特殊的企业/公文字体（如仿宋_GB2312、楷体、小标宋、方正字体）并希望 100% 像素级对齐，只需在 Word 中开启： 【文件】→【选项】→【保存】→ 勾选【将字体嵌入文件】。转换引擎将自动提取内嵌原字体进行高保真矢量渲染。

High-Performance Client-Side WebAssembly Engine

The parser unpacks XML structures, processes vector typography, and generates PDF streams entirely in your browser's private memory space.
