图片旋转
在浏览器内按-360°至360°任意角度旋转JPEG、PNG、WebP图片，提供90°/180°快捷旋转，扩展画布避免裁切并保持原格式下载。
使用步骤
如何使用
- Choose a JPEG, PNG, or WebP image up to 20 MB and 40 megapixels.
- Enter an angle from -360° to 360°, or use a 90° or 180° quick turn.
- Rotate the image, review the expanded result, and download it.
Rotate without clipping
The output canvas expands to the smallest whole-pixel rectangle that contains the rotated image. A quarter turn swaps width and height; diagonal angles usually create a larger outer rectangle.
Local processing and format limits
The image is decoded and rotated on your device. PNG and WebP can keep transparent corners, while JPEG corners use white because JPEG has no transparency. Canvas output does not retain source metadata.
常见问题
你可能还想知道
Which direction is a positive angle?
Positive angles rotate clockwise on this page; negative angles rotate counterclockwise.
Will the image corners be cut off?
No. The output canvas expands to contain the complete rotated image, subject to the 10,000-pixel and 40-megapixel output limits.
Does rotation upload my image?
No. Rotation runs locally in your browser.
