PDF 拆分的常见用法

从一份大文件里取几页。最常见的是:一本几十页的 PDF 里只需要其中两页材料、成绩单只要成绩那一页、招标文件只要资质页。用「按页码提取」填 1-3,5,8-10 这样的区间即可,输出是一份新 PDF,原始文件不受影响。

把长文件切成多份。投递平台常限制单个附件大小或页数;资料需要分给不同的人;讲义要按章节分发——用「每 N 页一份」,100 页的 PDF 设成每份 20 页,就会生成 5 个文件并自动打包成 zip 下载,省去逐个保存的麻烦。

关于页码范围写法。支持逗号分隔、区间混合,也支持中文逗号与顿号:1-3,5、1,3,5-7 都可以。页码从 1 开始。超出总页数的部分会被自动忽略,并在页面上提示,不会导致失败;重复的页码只保留一次,结果按页序排列。

Privacy note:拆分过程完全在你的浏览器内完成,PDF 不会被上传到任何服务器。合同、成绩单、银行流水这类敏感材料可以放心处理,可在浏览器开发者工具的 Network 面板核验没有文件上传请求。

FAQ

Will splitting modify my original file?

No. The original file is only read; the output is brand-new files. The page keeps no copies either - refreshing clears everything.

It says the PDF is encrypted - what now?

PDFs with an open password cannot be parsed in the browser. First open the file in a reader (Adobe Acrobat, the system preview, etc.), enter the password, save a copy without the password, then upload that copy for splitting.

Do the extracted pages get blurrier?

No. Extraction copies the page objects verbatim into the new document - no re-encoding, no recompression.

Can I split several PDFs at once?

This page processes one file at a time. Handle several files one after another, or merge them first with our PDF merge tool and split the result.
