你在 PDF 中看到的顺序并非永久固定在一个长文档上。它的页面是按序列排列的独立对象，这意味着更改该序列无需将文档转换为图像并从头开始重建每一页。 这就是我的工作原理。将页面拖动到其他位置，它在序列中的位置就会随之改变。选择多个页面，它们可以在保持彼此相对顺序的同时一起移动。旋转属性属于页面，复制会创建另一个可操作的引用，而删除页面更改的是你正在准备的新文档，而非你最初打开的文件。 当你保存时，我会按照你创建的顺序生成一个新的 PDF。原文件保持不变。所有操作均在浏览器的本地设备上完成。Guides 中有关于重新排序、旋转、复制以及一次性组织多个页面的更详细说明。
The order you see in a PDF is not painted permanently onto one long document. Its pages are separate objects arranged in a sequence, which means changing that sequence does not require turning the document into images and rebuilding every page from scratch. That is what I work with. Drag a page somewhere else and its place in the sequence changes. Select several pages and they can move together while keeping their order relative to each other. Rotation belongs to the page, duplication creates another reference to work with, and removing a page changes the new document you are preparing rather than the file you originally opened. When you save, I write a new PDF in the order you created. The original stays where it was. Everything happens on your device in the browser. Guides has longer notes on reordering, rotating, duplicating, and organizing many pages at once.
