如何使用「长图转 PDF（自动分页）」？How do I use the Long Image to PDF (Auto Page Split)?
选择一张或多张长图，选择页面大小（打印选 A4）和页边距，勾选“智能分页”。预览会显示每一页的分割位置，确认后点“生成 PDF”。Choose one or more long images, pick a page size (A4 for printing) and margins, and keep Smart page breaks on. The preview shows where each page breaks; then press Create PDF.
长图转 PDF 后打印会不会很小？Will the printout be tiny?
不会。工具按页面宽度缩放长图，再按页面高度分成多页，每页的字和普通文档差不多大，而不是把整张长图缩到一页里。No. The image is scaled to the page width and then broken into pages, so text prints at a normal size instead of squeezing everything onto one page.
能把多张长图合成一个 PDF 吗？Can several long images go into one PDF?
可以。一次选择多张图片，拖动排序，它们会按顺序依次分页合并到同一个 PDF 文件中。Yes. Select several images, drag to order, and they are paginated into one PDF in sequence.
生成的 PDF 文件太大怎么办？The PDF is too large — what now?
把“图片画质”调低一些（例如 75%），或者生成后再用“PDF 压缩”工具压缩。Lower the image quality (e.g. 75%), or compress the result with Compress PDF.
