一步一步来。One step at a time.
打开“提取几页”Choose Extract pages
打开合页 PDF，选择“提取几页”，然后添加文件。有多份文件时，先确认当前选中的是你要提取的那份。Open Heye PDF, choose Extract pages, and add your file. If you added several files, check that the correct one is selected.
按实际页面位置填写Use the physical page positions
输入单个页码或连续范围，用英文逗号分隔，例如 1,3-5。页码从 1 开始，不能大于文档总页数。封面也算一页；印在页面上的编号可能与实际位置不同。Enter single pages or ranges separated by commas, such as 1,3-5. Pages start at 1 and cannot exceed the document's page count. A cover counts as a page; printed page labels may differ from physical positions.
提取并下载Extract and download
点击“提取并下载”。所选页按照你写入的顺序放入新 PDF；重复页码只保留一次。原文件不会被这个操作覆盖。Click Extract & download. The new PDF follows the order you entered, with repeated page numbers included only once. This action does not overwrite the original file.
重新打开导出文件Open the exported PDF
在常用 PDF 阅读器中检查页数与顺序，也看看图表、文字和方向是否正确。确认无误后再交给接收方。Use your usual PDF reader to check the page count and order, along with text, graphics, and orientation. Check the result before sharing it.
可以照着核对的小例子A SMALL EXAMPLE TO CHECK
六页 PDF，保留四页Keep four pages from a six-page PDF
下面的范围会保留第 1、3、4、5 页，按这个顺序导出一份四页 PDF。This range keeps pages 1, 3, 4, and 5, producing a four-page PDF in that order.
输入或设置Input or settings
1,3-5结果核对Result check
1 → 3 → 4 → 5
共 4 页1 → 3 → 4 → 5
4 pages这些边界，也说清楚。Keep these limits in mind.
这是按页面提取，不会识别扫描件文字，也不会把 PDF 自动转成 Word。This extracts pages. It does not recognize scanned text or automatically convert a PDF to Word.
加密、损坏或非常大的文件可能无法处理。手机可先用较小文件；有读取错误时不要把空白或不完整输出当作成功。Encrypted, damaged, or very large files may fail. Start with smaller files on a phone, and do not treat a blank or incomplete output as a successful result.
文件处理在浏览器中进行。页面仍可能连接托管、广告，以及你允许的访问统计服务；“本地处理”不等于整个网页没有网络连接。File processing happens in your browser. The page may still connect to hosting, advertising, and analytics you allow; local processing does not mean the entire webpage has no network connections. 查看隐私说明Read the privacy notice ↗
