合并与重排页面
将多个文件中的单独页面拖动排列成任意顺序。
使用方法
上传多个 PDF，将页面缩略图拖动到您想要的顺序（移除不需要的页面），然后下载合并后的单个 PDF。
这与“合并 PDF”有什么区别？
“合并 PDF”按选定顺序合并整份文件。而此工具在页面级别操作——您可以从任意上传的文件中挑选单独的页面，拖动排列成您想要的确切顺序，跳过不需要的页面。
我可以重复使用同一页吗？
不能直接做到——每个页面缩略图对应一个文件中的一页。如果需要该页再出现一次，请重新上传该文件。
Can I remove pages I don't want in the final file?
Yes — any page thumbnail you don't drag into the final order is simply left out of the combined PDF.
How many files can I combine at once?
As many as you like — since everything runs in your browser, the only limit is your device's available memory.
Do pages keep their original quality when reordered?
Yes — pages are copied as-is; reordering doesn't re-render, recompress, or otherwise change their content.
Do my files get uploaded anywhere?
No — everything runs in your browser tab using WebAssembly. Nothing is sent to a server, so there's no upload to wait on and no copy of your file sitting on someone else's disk waiting to be deleted later, because it was never sent anywhere in the first place.
Does this work with scanned PDFs or pages that are just images?
Yes — each page is copied as a complete object, not re-read or re-rendered, so it works the same whether the page holds real text, a scanned image, or a mix of both.
