一年三百多的 PDF 软件，我只用拆页合并加水印，其余功能一次没点。 BentoPDF 开源 PDF 工具箱，合并/拆分/压缩/水印/转图/加密全有，全本地处理不上传。 alam00000/bentopdf
BentoPDF 拆分 PDF 时，一个容易选错的选项（附样例） 试了下 BentoPDF 的合并和拆分，功能不复杂，但拆分时有个选项容易弄错：填了 1-2, 3，默认还是只生成一份 PDF 。要分别保存，得把 Output 改成 One PDF per range。 顺便做了两份样例，一份两页、一份一页。合并后再拆回来，对照检查了文字和页面顺序，这组文件没有发现变化。输入文件和处理结果都放在下载包里，有需要可以拿去试。 工具：[BentoPDF]( bentopdf.com) · [源码]( alam00000/bentopdf) 样例：[Google Drive 下载，约 282 KB]( drive.google.com) 我不是这个项目的开发者，这里分享一下操作过程。 先合并 解压练习包，samples 里有两份文件： - 01_brief_A.pdf，两页。 - 02_appendix_B.pdf，一页。 打开 Merge PDF，把这两份文件加进去，A 放前面，B 放后面。顺序反了就拖动调整。 使用 File Mode，旁边的 Pages 留空，其他选项保持默认，点击 Merge PDFs 下载。 结果应该是三页。样例的每页底部都写了编号，翻一下就能确认顺序： LAB-A1 → LAB-A2 → LAB-B1 也可以打开包里的 expected/01_merged.pdf 对照。我检查了这组文件里的中文、金额和算式，都保留了下来。 再拆成两份 打开 Split PDF，选中刚合并的文件，按下面填写： Split Mode：Extract by Page Range Page Range：1-2, 3 Output：One PDF per range 点击 Split PDF，下载并解压后，会得到两份文件：前两页一份，第三页一份。 要留意的就是 Output。默认的 Single combined PDF 会把选中的页面放进同一份文件，所以即便填了两个范围，也不会自动拆成两份。如果下载后发现还是一个三页 PDF ，先看这里。 这次测试用的是 BentoPDF 2.8.10 ，本机运行的官方静态包。在线版界面可能有变化，包里也放了固定版本的复现说明。 样例都是合成资料，不含真实业务信息。这组普通 PDF 的合并、拆分结果正常；带密码、数字签名、可填写表单的文件，以及大文件，还没试过。 如果你遇到过拆分后文字丢失、页面尺寸变化之类的问题，可以说说文件类型和具体操作，私人文件就不用贴了。
