翻转 PDF
将每一页水平或垂直镜像。
使用方法
上传您的 PDF，选择水平或垂直方向，然后下载结果——每一页都会沿该轴镜像。
什么情况下需要翻转页面？
扫描件出现镜像（例如某些双面扫描仪或平板扫描仪进纸方向颠倒造成的），或某种布局需要左右镜像的页面。
翻转也会旋转页面吗？
不会——翻转是沿某一轴镜像内容，而不是旋转。如果需要把横向或颠倒的页面转正，请使用“旋转 PDF”。
Can I flip only some pages, not the whole document?
No — the flip applies to every page in the file. For a mixed document, split out the pages that need flipping first, flip that file, then merge them back.
Does flipping mirror the text, making it unreadable?
Yes — flipping mirrors everything on the page, including text. It's meant for correcting mirrored scans, not for creating a mirrored effect on readable content.
What's the difference between flip and rotate?
Rotate turns the page around a point, like a clock hand; flip mirrors it across an axis, like a reflection. A rotated page still reads normally; a flipped one reads backwards.
What's the difference between horizontal and vertical flip?
Horizontal flips left to right, like a mirror facing the page — the left edge ends up on the right. Vertical flips top to bottom — the top edge ends up on the bottom. Either way the content itself is mirrored, so text reads backwards.
Can I use this for iron-on transfers?
Yes — that's one of the main reasons people use it. Flip horizontally before printing, and the mirrored image prints the right way round once it's pressed onto fabric.
