Use Split PDF when one page should become its own file
If you need page 4 from a report, one signed page from a contract packet, or a single scan from a bundle, 拆分 PDF is the right tool. Select just that page and export a new file.

How to extract one page from a PDF
Extracting one page is a narrower version of page extraction. The goal is not to trim the original document a little. The goal is to save one selected page as its own standalone PDF.
This is different from deleting pages
If you want to keep the original file but remove one page from it, that is a 删除 PDF 页面 workflow instead. Extraction creates a new file. Removal edits what remains.
Rotate first if the target page is sideways
If the page you want is sideways in the source file, fix orientation with 旋转 PDF before you export. That is especially useful for scans and mixed-orientation packets.
Check whether the page is worth cleaning first
If the page is surrounded by blank pages or duplicates, it can be simpler to clean the source document first, then export the one page you want.
Typical examples
Common cases include sending one appendix page, isolating one invoice sheet, extracting a signed approval page, or keeping one receipt from a larger scan.
