旋轉 PDF
幾秒鐘內修正橫向或顛倒的頁面。
運作方式
選擇 90°、180°、270° 或完整 360° 旋轉，預覽結果後下載——每一頁都會以相同方式旋轉，全程在您的瀏覽器中完成。
我可以只旋轉一頁，而不是整份 PDF 嗎？
目前「旋轉 PDF」會對檔案中的每一頁套用同一個旋轉角度。若文件的頁面方向不一致，請先使用「分割 PDF」，旋轉該頁所在的檔案，再用「合併 PDF」將它們合併回去。
旋轉會降低 PDF 的品質嗎？
不會——旋轉只是改變頁面方向，並不會重新產生內容，因此畫質與檔案大小都不會改變。
Does rotating change the page size?
For a 90° or 270° rotation, width and height swap (a portrait page becomes landscape). 180° keeps the same dimensions, just upside down.
Can I preview before downloading?
Yes — the preview updates live as you choose a rotation, so you can confirm it looks right before downloading.
Will this fix pages that were scanned at a slight angle, not just sideways?
No — this tool rotates in fixed 90° increments. A slightly skewed scan needs a de-skew tool, which isn't what Rotate PDF does.
Can I rotate different pages in different directions?
Yes — in "Rotate pages individually," each page rotates on its own. Turn page 2 one way and page 5 another, and every other page stays exactly as it was.
Will it still rotate correctly if my scanner already rotated some pages?
Yes — each rotation is added on top of whatever orientation the page already has, not reset to zero. So a page your scanner rotated 90° that you then rotate another 90° ends up at 180°, not stuck back at 0°.
What if only one page out of many needs fixing?
Use "Rotate pages individually" — click just that one page in the grid until it's upright, then download. Every other page keeps its original content and quality, untouched.
