使い方
使い方
- 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.

Does rotation upload my image?
No. Rotation runs locally in your browser.
