常見問題

How do I fix a sideways photo?

Drop the photo and click "90° CW" (clockwise) or "90° CCW" (counter-clockwise). Most sideways phones photos need one 90° rotation to become upright.

Can I rotate by any angle?

Yes. The angle slider accepts any value from -180° to 180°. Use negative values for counter-clockwise rotation, positive for clockwise.

Will rotating affect image quality?

For 90° and 180° rotations, there is no quality loss if you use PNG output. For custom angles, a slight quality reduction occurs because pixel interpolation is needed. JPEG/WebP also introduces compression.

What happens to transparent corners after a custom angle rotation?

Non-90° rotations create triangular transparent corners. Use PNG output to preserve transparency. JPEG output fills corners with white.

Can I batch rotate multiple images?

Yes. Drop multiple files, set the angle, and click "Rotate all". All files are rotated by the same angle and available to download individually.

What image formats are supported?

JPEG, PNG, WebP, and AVIF as input. Output can be JPEG, PNG, or WebP.
