如何使用「PDF 提取页面」？How do I use the Extract PDF Pages tool?
在「PDF 提取页面」中，选择或拖入文件，按需设置「要提取的页」等选项，然后点击「提取为新 PDF」按钮即可。加密的 PDF 会提示输入密码（出现「打开密码」栏和「打开」按钮），输入密码并点「打开」后再继续。In the Extract PDF Pages: Choose or drop your files, set "Pages to extract", then click "Extract to new PDF". For an encrypted PDF, the page asks for its password (a Password field and an Open button appear) — enter it, click Open, then continue.
页码范围怎么写？How do I write page ranges?
用逗号分隔，例如 1-3,5,8- 表示第 1 到 3 页、第 5 页和第 8 页到最后一页；-3 表示前 3 页。也可以直接点击下方的页面缩略图来选择。Separate with commas: 1-3,5,8- means pages 1 to 3, page 5, and page 8 to the end; -3 means the first three pages. You can also click the page thumbnails below.
提取的页面顺序可以调整吗？Can I change the page order?
可以。页面会按你输入或点击缩略图的顺序排列，例如输入 5,2-3（或依次点击第 5、2、3 页）会得到第 5、2、3 页；重复的页码只保留一次。Yes. Pages appear in the order you type them or click the thumbnails — 5,2-3 (or clicking pages 5, 2, 3 in turn) gives pages 5, 2, 3. Duplicate page numbers are kept only once.
和“拆分 PDF”有什么区别？How is this different from Split PDF?
提取是把选中的页面放进同一个新 PDF；拆分是把文档切成多个独立文件。Extract puts the chosen pages into one new PDF; Split cuts the document into several separate files.
加密的 PDF 可以处理吗？Can it handle password-protected PDFs?
可以。如果 PDF 需要打开密码，会提示你输入；只有权限限制（无打开密码）的文件会自动打开。输出文件不再带密码，如需加密请使用“PDF 加密”工具。Yes. If the PDF needs an open password you'll be asked for it; files with only permission restrictions open automatically. The output is not password-protected — use the Protect PDF tool if needed.
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.
