よくある質問

How do I rotate an image?

Upload your image, then use the Rotate Left and Rotate Right buttons for 90° steps, or drag the angle slider for a precise custom angle. Click Download to save.

Can I rotate by a custom angle, not just 90°?

Yes. The angle slider lets you rotate to any degree from −180° to 180°, which is ideal for straightening a slightly crooked horizon. The canvas expands so no corners are cut off.

Will rotating cut off the corners of my photo?

No. For custom angles the canvas is enlarged to fit the whole rotated image, with transparent (PNG) or white (JPG) padding in the corners — nothing is cropped.

Does rotating reduce quality?

90°, 180°, and 270° rotations are lossless. Custom angles are re-sampled once at full resolution, so quality stays high. PNG output is lossless.

Are my images uploaded anywhere?

No. Rotation happens entirely in your browser via the Canvas API — your images never leave your device.

What formats are supported?

Upload PNG, JPG, JPEG, WebP, or BMP. Export as PNG, JPG, or WebP at the original resolution.
