Convert Markdown or HTML into a paginated A4 PDF you can download — all rendering happens locally.
把 Markdown 或 HTML 转成分页 A4 PDF 并下载，渲染全过程都在本地完成。
A Markdown-to-PDF converter that produces a real paginated A4 document rather than a long screenshot. The page is laid out, captured at double scale for crisp output, and split across A4 pages with proper margins; tables and code blocks are preserved. Both Markdown and raw HTML inputs are accepted, so a styled HTML snippet converts just as well.
一个把 Markdown 转成真正分页 A4 文档、而不是一张超长截图的转换器。页面先排版，再以两倍分辨率捕获，最后按 A4 页高切分并保留页边距，表格与代码块都会保留。Markdown 与原始 HTML 都能输入，带样式的 HTML 片段同样适用。
The document is rendered into a canvas at double scale, so the PDF is a high-resolution image. That guarantees identical layout everywhere, at the cost of selectable text — for selectable output, print to PDF from your browser instead.
文档以两倍分辨率渲染到画布再嵌入 PDF，因此是高清图片。好处是任何设备上版式完全一致，代价是文字不可选中——若需要可选择的文本，请用浏览器自带的"打印为 PDF"。
The rendered height is divided by the A4 page height and the remainder is carried onto the next page, so long documents become multi-page PDFs instead of one squeezed image.
渲染高度除以 A4 页高，余量带到下一页，因此长文档会变成多页 PDF，而不是被压扁的一张图。
Yes. If the input starts with a tag it is treated as HTML and rendered as-is; otherwise it is parsed as Markdown first.
可以。输入以标签开头时按 HTML 原样渲染，否则先按 Markdown 解析。
No. Rendering and PDF assembly happen locally in the browser.
不会。渲染与 PDF 组装都在浏览器本地完成。
