About Rotate & Flip Image / 关于本工具
Sometimes a photo comes out sideways or upside down — a phone held at an angle, a scan fed in the wrong way, an image whose orientation tag got lost. Rotating turns the picture in 90° steps until it's upright. Flipping mirrors it: a horizontal flip swaps left and right (handy for selfies where text reads backwards, or to face a subject the other way), while a vertical flip mirrors top and bottom. These are lossless operations — rotating or flipping by 90° just rearranges existing pixels, so quality is untouched.
有时照片是横的或倒的——手机倾斜着拍、扫描时方向放反、方向标签丢失的图片。旋转以 90° 为步长把画面转正。翻转则是镜像：水平翻转左右对调（适合文字反了的自拍，或让主体朝向另一边），垂直翻转上下镜像。这些都是无损操作——90° 旋转或翻转只是重新排列已有像素，画质丝毫不受影响。
Rotate vs flip / 旋转与翻转的区别
Rotating preserves the scene exactly, just turned. Flipping creates a mirror image, so anything with text or a recognizable layout will read reversed — great for artistic mirroring, but don't flip a document you need to stay legible. If your phone photos keep appearing rotated on other devices, it's usually the EXIF orientation tag; saving a rotated copy here bakes the correct orientation into the pixels so it looks right everywhere.
旋转完整保留场景，只是转了个方向。翻转生成镜像，因此带文字或有可辨识版式的内容会变成反的——做艺术镜像很好，但需要保持可读的文档别翻转。如果你的手机照片在别的设备上总是显示成转向的，通常是 EXIF 方向标签在作怪；在此保存一份旋转后的副本，会把正确方向写进像素，处处都显示正常。
