使用说明与常见问题How-to & FAQ

「SVG 转 PDF（保留矢量）」是什么？What is the SVG to PDF Converter (Vector) tool?

把 SVG 矢量图（Logo、图标、图表、设计稿）转换为矢量 PDF：路径、渐变和文字保持矢量，可无限放大，文字仍可选中和搜索；按 SVG 声明的尺寸（px、mm、in 等）还原纸张大小，也可放到 A4/Letter 上，多个 SVG 合并为多页 PDF，本地完成不上传。Convert SVG graphics — logos, icons, charts and design files — into a vector PDF. Paths, gradients and text stay vector, so they scale without blur and the text can still be selected and searched. The page keeps the size the SVG declares (px, mm, in …) or fits A4/Letter, and several SVGs merge into a multi-page PDF. Local, nothing uploaded.

如何使用「SVG 转 PDF（保留矢量）」？How do I use the SVG to PDF Converter (Vector) tool?

在「SVG 转 PDF（保留矢量）」中，按需设置「页面大小」、「方向」、「页边距 (0–50 mm)」、「图片压缩」、「JPEG 质量 (30–100)」等选项，然后点击「生成 PDF」、「清空」按钮即可。支持拖放文件。In the SVG to PDF Converter (Vector): Set "Page size", "Orientation", "Margin (0–50 mm)", "Image compression", "JPEG quality (30–100)", then click "Create PDF", "Clear". Drag-and-drop files is supported.

PDF 里的 SVG 还是矢量的吗？Is the SVG still vector inside the PDF?

是。SVG 的路径、形状、渐变和文字会转换成 PDF 矢量内容（使用开源的 svg2pdf.js 和 jsPDF，MIT 许可，只在本工具里按需加载），放大不会模糊，文字可以选中和搜索。含中文、俄文等非西欧字符的文字会嵌入 Noto Sans SC 字体的子集。滤镜（模糊、阴影等）、遮罩和 foreignObject 在矢量 PDF 中可能缺失或被简化，遇到时结果下方会提示；SVG 里嵌入的位图（data: 图片）仍是位图。Yes. Paths, shapes, gradients and text are converted into PDF vector content (with the open-source svg2pdf.js and jsPDF, MIT-licensed, loaded only by this tool), so they stay sharp at any zoom and the text can be selected and searched. Text with Chinese, Cyrillic or other non-Western-European characters embeds a subset of Noto Sans SC. Filters (blur, shadows and so on), masks and foreignObject may be missing or simplified in the vector PDF, and a message under the result says so when they occur; bitmaps embedded in the SVG (data: images) stay bitmaps.

PDF 页面多大？What size is the PDF page?

选“按图片尺寸”时，页面等于 SVG 声明的物理尺寸：width/height 用 mm、cm、in、pt 时直接换算，用 px 或未写单位时按 96 px = 1 英寸；只有 viewBox 时用 viewBox 的宽高。选 A4、Letter 等纸张时图形居中放置：大于可用区域的会等比例缩小；“小图不放大”默认勾选，较小的图形保持原尺寸，取消勾选后会放大到填满页面。With Image size, the page matches the size the SVG declares: mm, cm, in and pt convert directly, and px or unitless values use 96 px = 1 inch; with only a viewBox, its width and height are used. With A4, Letter and so on, the graphic is centred: anything larger than the printable area is scaled down, and because "Don't enlarge small images" is ticked by default, smaller graphics keep their size — untick it to scale them up to fill the page.

为什么外部图片或字体没显示？Why are external images or fonts missing?

出于安全原因，工具不会加载 SVG 里链接到外部网址的图片、字体和样式表。请把图片嵌入为 data: URL；外部网页字体会换成 PDF 标准字体（西文）或 Noto Sans SC（中文等），需要精确字形时请先在设计软件里把文字转为路径。For security, images, fonts and stylesheets linked to outside addresses are not loaded. Embed images as data: URLs. External web fonts are replaced with the standard PDF fonts (Western text) or Noto Sans SC (Chinese and other scripts); if you need the exact letter shapes, convert text to paths in your design app first.

SVG 很大或页面尺寸很大会怎样？What about very large SVGs or page sizes?

矢量输出不受像素上限限制，2 米宽的海报也按原尺寸生成。单个文件最大 100 MB、最多 100 个文件；元素非常多（几十万个）的 SVG 转换会比较慢。Vector output has no pixel limit, so even a 2-metre poster is produced at full size. Each file can be up to 100 MB, up to 100 files at a time; SVGs with hundreds of thousands of elements take longer to convert.

图片会上传吗？Are my images uploaded?

不会。解码和生成 PDF 都在你的浏览器里完成（pdf-lib），图片不会离开你的设备。No. Decoding and PDF creation both happen in your browser (pdf-lib); your images never leave your device.
