旋转 PDF
几秒钟内修正横向或颠倒的页面。
使用方法
选择旋转 90°、180°、270° 或完整 360°，预览结果后下载——每一页都会以相同方式旋转，全程在您的浏览器中完成。
我可以只旋转一页，而不是整个 PDF 吗？
目前“旋转 PDF”会对文件中的每一页应用相同的旋转。如果文档中各页方向不一致，请先使用“拆分 PDF”，旋转需要调整的那一页，再用“合并 PDF”合并回去。
旋转会降低 PDF 画质吗？
不会——页面旋转是通过改变方向实现的，而非重新渲染内容，因此画质和文件大小保持不变。
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.
