Reverse PDF Pages
Reverse the page order of a PDF file
Reverse PDF Pages — what it does
Reverse the entire page order of a PDF, so the last page becomes the first. It sounds trivial and solves a very specific, very common problem: a document scanned from the back of the stack forward, which arrives complete but entirely inside out.
When this tool helps
- Correcting a scan produced by feeding a stack in the wrong direction.
- Preparing the reverse-side pages of a manual duplex print run, where the stack comes out inverted.
- Flipping a document assembled bottom-up back into reading order.
How to use it
- Choose the PDF file.
- Process the reversal.
- Download the reversed PDF.
- Check the first and last pages.
Accuracy, limits, and good practice
- Reversing is its own inverse — running it twice returns the original order, so a mistaken run costs nothing.
- For manual duplex printing, whether the even-page stack needs reversing depends on your printer's output stacking; test with four sheets first.
- Reversal moves whole pages, so any page numbers printed on the pages themselves will now run backwards.
- Check the page count before and after: reversal never changes it, so a different total means something else went wrong.
Frequently asked questions
Does it rotate the pages too?
No, only the order changes. Use the rotate tool if pages are also upside down.
Can I reverse only part of the document?
Not directly. Split out the section, reverse it, and merge it back into place.
Is any quality lost?
No, pages are copied intact; only their sequence in the file changes.
Can I reverse and rotate in one step?
No, run the tools in sequence. Reverse first, then rotate, and check the result after each step.

PDF 頁面反向排序能做什麼
把 PDF 的頁面順序整個反轉，讓最後一頁變成第一頁。聽起來微不足道，卻解決了一個非常具體又非常常見的問題：從整疊的背面往前掃描的文件，內容齊全但整份是反的。
什麼時候用得上
- 修正整疊送紙方向錯誤所產生的掃描檔。
- 為手動雙面列印準備背面頁，因為出紙常是倒過來堆疊的。
- 把由下往上組成的文件翻回閱讀順序。
使用步驟
- 選擇 PDF 檔案。
- 執行反轉。
- 下載反轉後的 PDF。
- 檢查第一頁與最後一頁。
精確度、限制與實務建議
- 反轉是自身的逆運算——執行兩次就回到原順序，所以做錯也不會有損失。
- 手動雙面列印時，偶數頁那疊要不要反轉，取決於印表機的出紙堆疊方式，建議先用四張紙測試。
- 反轉搬動的是整頁，因此印在頁面上的頁碼會變成倒著跑。
- 請比對處理前後的頁數：反轉不會改變頁數，總數不同就代表另有問題。
常見問題
會順便旋轉頁面嗎？
不會，只改順序。頁面若上下顛倒，請用旋轉工具處理。
可以只反轉部分頁面嗎？
無法直接處理。請先拆出該段落、反轉後再合併回原位。
會損失品質嗎？
不會，頁面完整複製，只有它們在檔案中的順序改變。
可以同時反轉又旋轉嗎？
不行，請依序使用兩個工具：先反轉再旋轉，每一步都確認結果。
