Quick 90°/180° rotation, free-angle slider, horizontal or vertical flip. Single image or batch — same transform applies to all.
Rotation runs on a hidden HTML5 canvas in your browser — your images never leave your device. Quick buttons apply 90°/180° or flips immediately. Free rotation rotates to any angle; the output canvas grows to fit the rotated image's bounding box (no cropping). When exporting to JPG, transparent areas around a non-90° rotation are filled with your chosen background colour.
