Rotate PDF
Rotate every page by 90, 180, or 270 degrees
Rotate PDF — what it does
Rotate every page of a PDF by 90, 180 or 270 degrees and download the corrected document. Scanned pages that come out sideways and landscape spreads that display upright are among the most common PDF annoyances, and this fixes both in a single pass.
When this tool helps
- Turning a document scanned in the wrong orientation into readable pages.
- Correcting landscape pages that display and print rotated.
- Fixing a batch of camera-photographed pages that all came out on their side.
How to use it
- Choose the PDF file.
- Select the rotation angle.
- Process the rotation.
- Download and verify the result.
Accuracy, limits, and good practice
- The rotation applies to every page, so a file mixing portrait and landscape orientations needs splitting and treating separately.
- Rotation is applied through the page's rotation property, so the content itself is untouched and no quality is lost.
- If pages still display oddly after rotating, try the reset rotation tool first and then rotate from a clean baseline.
- Rotate before adding page numbers or watermarks; text added first ends up sideways along with the page.
Frequently asked questions
Can I rotate just one page?
The rotation applies to the whole document. Split the page out, rotate it, and merge it back for a single page.
Does rotating reduce quality?
No, pages are rotated without re-rendering, so text stays selectable and images stay untouched.
Which direction is 90 degrees?
Clockwise. Use 270 for a counter-clockwise quarter turn, and 180 to turn a page upside down.
Does rotation change the page size?
A 90 or 270 degree turn swaps the effective width and height, which matters when the file goes to a printer expecting portrait pages.

旋轉 PDF能做什麼
把 PDF 每一頁旋轉 90、180 或 270 度，並下載修正後的文件。掃描出來橫躺的頁面、以及橫式跨頁卻直立顯示，是最常見的兩種 PDF 惱人問題，這裡一次解決。
什麼時候用得上
- 把方向掃錯的文件轉成可閱讀的頁面。
- 修正顯示與列印都是旋轉狀態的橫式頁面。
- 修正一整批全部橫躺的手機翻拍頁面。
使用步驟
- 選擇 PDF 檔案。
- 選擇旋轉角度。
- 執行旋轉。
- 下載並確認結果。
精確度、限制與實務建議
- 旋轉套用到每一頁，直式與橫式混排的檔案需要先拆分再分別處理。
- 旋轉透過頁面的旋轉屬性套用，內容本身不動，因此不會有畫質損失。
- 旋轉後仍顯示怪異時，可先用重設旋轉工具回到乾淨基準，再重新旋轉。
- 請在加頁碼或浮水印之前先旋轉；先加的文字會跟著頁面一起轉成橫的。
常見問題
可以只旋轉其中一頁嗎？
旋轉套用到整份文件。單頁需求請先拆出該頁、旋轉後再合併回去。
旋轉會降低品質嗎？
不會，頁面不需重新算繪即可旋轉，文字仍可選取、圖片也未被更動。
90 度是哪個方向？
順時針。逆時針四分之一圈請用 270 度，上下顛倒請用 180 度。
旋轉會改變頁面尺寸嗎？
轉 90 或 270 度會讓實際寬高對調，若印表機預期收到直式頁面，這一點就很重要。
