从 PDF 中删除重复页
自动查找重复的页面——删除前先查看并确认。
使用方法
1. 上传您的 PDF。2. 与之前某一页完全相同的页面会自动预选。3. 查看并调整所选内容，然后删除它们。
它是如何检测重复页的？
系统会将每一页的外观与之前的每一页进行比对——完全匹配的页面会被预先选中，保留首次出现的那一页并标记重复项。这对扫描页面和数字页面同样适用。
它能识别相似但不完全相同的页面吗？
不能——此功能只查找完全一致的重复项，而非近似匹配。哪怕只有细微差异的两个页面也不会被标记，因此不会误删任何内容。
Can it find duplicates across multiple PDF files?
No — it only compares pages within the one file you upload. If you need to dedupe across several PDFs, merge them into a single file first, then run this tool on the merged result.
Why does my PDF have duplicate pages in the first place?
Usually it's a scanning issue — a double-sided document scanned as single-sided runs through the scanner twice, or a feeder picks up the same sheet more than once. It also happens when files get merged more than once, or a print job duplicates a page. Either way, this tool finds the repeats so you don't have to scroll through hunting for them.
