工具介绍
PDF 页面提取在浏览器里完成:打开一个 PDF,输入要保留的页码,生成一份只含这些页的新 PDF。文件不上传,也没有网络请求。 Extraction happens in your browser: open a PDF, type the pages you want to keep, and get a new PDF containing only those pages. Nothing is uploaded and no request is made.
页码从 1 开始,支持 `1-3,5` 这样的区间与分段,也容忍中文逗号和顿号。可以只留一页、删掉不需要的页,或把长文档拆成几个部分分别导出。 Pages are 1-based and ranges like `1-3,5` are supported, including full-width commas. Keep a single page, drop unwanted pages, or split a long document into parts.

使用说明

- 在页码范围里填写要保留的页,例如 `1-3,5`;点“全部页”可恢复整份文档。Enter the pages to keep, e.g. `1-3,5`; press All pages to reset.
- 确认“选中页数”无误后点“提取页面”。Check the selected-page count, then press Extract pages.
- 点“下载新 PDF”保存结果,原文件不会被修改。Download the new PDF; the original file is untouched.
常见问题
提取会改变原文件吗?Does extraction change the original?
不会。原文件只被读取,新页面写入一份全新的 PDF,原文件保持不变。No. The original is only read; pages go into a brand-new PDF.
页码写错了会怎样?What if my range is wrong?
一旦超出总页数或格式不对,页面会提示无效并禁用提取按钮,不会生成半成品文件。If a number exceeds the total or the format is wrong, the page flags it and disables extraction — no partial file is produced.
能一次拆成多个文件吗?Can it split into several files at once?
当前一次生成一个 PDF。需要拆成多份时,按不同页码范围重复提取即可。One PDF per run. For several outputs, repeat with different ranges.
加密 PDF 能提取吗?Can encrypted PDFs be extracted?
不能。需要先解除密码;页面会提示读取失败或加密。No. Remove the password first; the page will report a read or encryption failure.
