这款工具的作用
This deletes the pages you name and rebuilds the document from the ones that remain. The surviving pages are copied without being re-encoded, so nothing about them changes except their numbering.
Reach for it when a document arrived with pages you do not want to pass on: a cover sheet from a fax, blank separators a scanner inserted, an internal appendix that should not go to a client, or duplicate pages a feeder pulled twice.
工作原理
- Drop the PDF onto this page and wait for the page count to appear.
- Type the pages to delete. Single numbers, ranges and the words odd, even and last all work, and they can be mixed.
- Check the count of pages that will be removed, shown before you commit.
- Press Remove pages.
- The download starts by itself.
The range you type describes what goes away, not what stays. That sounds obvious, but it is the opposite of Extract pages, and it is worth being deliberate about which of the two you actually want - the same input produces opposite results in each.
Removing every page is refused rather than performed. A PDF with no pages is a file no reader will open, so instead of writing something broken the tool explains what happened.
The file usually shrinks by less than you expect. Removing a page removes its content stream, but shared resources such as fonts and a repeated letterhead stay behind if any surviving page still references them. If size is the goal, follow up with Compress PDF.
Bookmarks pointing at deleted pages are dropped, and anything nested beneath them is promoted rather than deleted with them, so removing a chapter opener does not silently take its sections away too.
常见问题
- 怎样写出要删除的页面？
- 用逗号分隔的单个数字、范围或关键词：3 删除一页，4-9 删除一段，12- 删除第 12 页到末尾的所有页面，odd 删除所有奇数页，last 删除最后一页。它们可以组合使用，例如 1, 5-7, last。
- 之后还能把页面找回来吗？
- 从输出文件里找不回——那些页面确实没了。不过你的原件丝毫不变，因为这款工具从不修改你拖入的文件，而是写一个新文件。在你检查完结果之前，请保留原件。
- 它能帮我找出空白页吗？
- 暂时不能。一页可能看起来空白却带有不可见的内容，猜错会删掉你需要的东西。目前请打开文档，记下哪些页是空白的，然后把它们列出来。
- 为什么删掉一半页面后文件几乎没变小？
- 因为大部分体积通常在共享资源里——嵌入字体、每页都有的徽标、颜色配置——只要还有页面用到它们，它们就会留下。如果你想解决的是文件大小，之后运行压缩 PDF。
