拆分 PDF
将 PDF 拆分为独立页面，每一页均可单独下载。
使用方法
上传您的 PDF，即可立即按页拆分为多个文件，随时单独下载。
我可以一次性下载所有拆分后的页面吗？
可以——拆分完成后，使用“以 ZIP 格式下载全部”即可将所有文件打包下载，也可以逐个单独下载。
按文件大小拆分是如何工作的？
设置一个目标大小（例如 1MB），页面会被分成若干连续的分组，每组都控制在该限制以内——当上传平台是按文件而非按页限制大小时，这个方法非常实用。
拆分会改变页面内容或质量吗？
不会——每一页都保留原始内容、格式和分辨率。拆分只是把页面分开，不会重新渲染或重新压缩。
Can I extract a specific page range, like pages 3 to 8, as one file?
Yes — pick "Custom pages" and type the range (e.g. "3-8"). You can also list several groups at once, comma-separated (e.g. "1-3, 5, 8-10"), and each group downloads as its own file.
Is there a limit on how many pages I can split?
No — since it all runs in your browser, the only real limit is your device's available memory, not a cap we impose.
Is my PDF uploaded when I split it?
No — splitting happens entirely in your browser. Your file never leaves your device or touches a server. Most online splitters upload your PDF and promise to delete it after an hour or a day; here there's nothing to delete, because nothing was ever sent anywhere.

Can I split a PDF on my phone — iPhone or Android?
Yes. The same browser-based tool works on mobile Safari and Chrome — tap to upload from Files, iCloud Drive, or your device storage, pick a split mode, and download the result. No app to install.
Can I split a PDF by chapter, bookmark, or a text marker instead of page numbers?
