Why this tool?
Photo came out sideways?
Phones sometimes save EXIF rotation data that apps ignore. One click fixes it permanently — no more "why is it sideways everywhere?"
Expand vs Crop
Expand grows the canvas to fit the full rotated image — perfect for odd angles. Crop keeps the original dimensions and trims the corners.
Any angle, not just 90°
Drag the slider or type any value from −360° to +360°. Useful for straightening a slightly tilted scan or horizon.
