如何使用「PDF 转 EPUB 电子书」？How do I use the PDF to EPUB Converter tool?

什么样的 PDF 适合转 EPUB？Which PDFs convert well to EPUB?
以连续文字为主的小说、文章、报告效果最好：段落会被合并成可重排的文本，在小屏幕上自动换行。图片、表格、公式和复杂排版不会保留，扫描件需要先 OCR。Text-heavy novels, articles and reports work best: paragraphs become reflowable text that wraps on small screens. Images, tables, formulas and complex layouts are not kept, and scans need OCR first.
章节是怎么划分的？How are chapters created?
“按标题分章”会把明显大于正文字号的文字识别为章节标题，在那里开始新章节；“按页数分章”则每 N 页一章。两种方式都会生成 EPUB 目录。By headings starts a new chapter at text noticeably larger than body text; By page count makes a chapter every N pages. Both generate an EPUB table of contents.
能在 Kindle 上阅读吗？Can I read it on a Kindle?
生成的是标准 EPUB 3（同时包含 EPUB 2 的 NCX 目录），Apple Books、多看、微信读书导入、Kobo 等可直接打开；Kindle 可通过“发送到 Kindle”上传 EPUB 自动转换。It's a standard EPUB 3 (with an EPUB 2 NCX table of contents for older readers), opening directly in Apple Books, Kobo and most reader apps; for Kindle, upload it via Send to Kindle, which converts EPUB automatically.
扫描件可以转换吗？Can scanned PDFs be converted?
本工具读取 PDF 自带的文字层，不做 OCR 文字识别。扫描件或纯图片 PDF 没有文字层，会提示“没有找到可提取的文字”；这种情况需要先用 OCR 软件识别。This tool reads the PDF's built-in text layer and does not perform OCR. Scans and image-only PDFs have no text layer, so you'll see "No extractable text found"; run them through OCR software first.
文件会上传到服务器吗？Are my files uploaded?
不会。PDF 在你的浏览器里用 pdf-lib / pdf.js 处理，文件不会离开你的设备，关闭页面后不留存任何数据。No. The PDF is processed in your browser with pdf-lib / pdf.js; files never leave your device and nothing is kept after you close the page.
