这款工具的作用
Extracting builds a new document from the pages you name, leaving the original alone. The pages are copied rather than re-rendered, so the result is identical in quality to the source.
Use it when only part of a document is relevant to someone: one signed page of a long contract, the two pages of a bank statement an application asks for, a single chapter of a manual, or the one certificate inside a bundle of scans.
工作原理
- Drop the PDF onto this page.
- Type the pages you want to keep. Ranges, individual pages, odd, even and last all work.
- Choose one document containing everything you selected, or one file per page.
- Press Extract pages.
- Download the result, or take all the files as a ZIP if you chose one per page.
The order you type is the order you get. Asking for 5, 1, 3 produces a document in that sequence, not sorted back into 1, 3, 5. This is deliberate: it makes the tool useful for rebuilding a document as well as for pulling pieces out of one, and it means you rarely need a separate reordering step afterwards.
Extracting differs from splitting in what it produces. Extract gives you one document from a selection that may be scattered across the original; split cuts the original into several documents at boundaries you set. If you want three separate files, use Split PDF.
Because the pages are copied rather than re-created, a page carrying a form field, a hyperlink or an annotation keeps them. Scanned pages keep their original image data at full resolution.
Nothing is uploaded. The extraction happens in a Web Worker in your browser, which is also why a slow connection costs you nothing once the page is open.
常见问题
- 页面框里可以输入什么?
- 单个页面、范围和关键词:4、2-8、10- 表示第 10 页起的所有页面、-3 表示前三页、odd、even、last,以及 last-2 表示倒数第二页。用逗号分隔多个。
- 页面会按我输入的顺序出来吗?
- 会。你输入的顺序就是输出中的顺序,所以 9, 2, 5 会按这个顺序生成这三页。如果你想按文档顺序排列,就照那样输入,或使用一个范围。
- 我能让每一页成为单独的文件吗?
- 可以,选择每页一个文件。每个输出以原文件名加上其页码命名,页码补零以便文件正确排序,并且全部可以一起打包为 ZIP 下载。
- 提取会降低质量吗?
- 不会。页面是在对象层面复制的,而不是重新渲染,因此文本仍是文本,图像保持原有的分辨率和编码,任何内容都不会被重新压缩。
