画像の回転

What this tool does

Rotate Image rotates a photo or graphic to any angle between -180° and 180°, with quick presets for 90° and 180° turns. Output renders instantly so you can preview, tweak, and export without waiting.

Choosing an angle

Use -90° / 90° / 180° quick buttons for common turns. Switch to Custom for any angle in between — drag the slider or type into the angle field for pixel-precise control.

Background and sizing

For non-90° rotations, the corners are empty. Pick a Transparent, White, or Custom Color fill. Use Keep original image size to preserve the canvas, or Auto crop to fit to remove empty corners by cropping the rotated content.

What does Rotate Image do?

It rotates a photo or graphic by 90°, 180°, -90°, or any angle from -180° to 180°. The original pixels are kept intact — only orientation changes — and the result renders instantly so you can compare and export without waiting.

Who needs an image rotator?

Photographers fixing portrait/landscape orientation, designers tilting layout assets, marketers prepping social posts, and anyone who shot a photo upside-down on their phone.

When should I use Auto crop to fit?

Pick Auto crop to fit when you want no transparent corners after rotation. It crops the largest rectangle of the original aspect ratio that fits inside the rotated image, so the output keeps the original look with no padding.

Where does the processing happen?

Entirely inside your browser via canvas. The image file never leaves your device, no upload, no server.

Why does the background option exist?

Rotating by anything other than 0° or 180° creates empty corners. Choose Transparent (PNG/WebP only), White, or a Custom Color to fill those corners.

How do I preserve the original canvas size?

Enable Keep original image size. The output canvas matches the input dimensions; the rotated content may extend past the edges and be cut, with empty corners filled by the chosen background.
