Image Rotator

Image rotation is a fundamental image manipulation technique used in photography, graphic design, and web development. Whether you need to correct an upside-down photo or create an artistic effect, rotating images is a common task.

How Canvas Rotation Works

This tool uses the HTML5 Canvas API to rotate images. The process involves translating the canvas origin to the center, applying a rotation transform with ctx.rotate(), and then drawing the image centered at that origin. When rotating by arbitrary angles, the canvas dimensions are automatically expanded to fit the rotated image without clipping.

Common Use Cases

• Correcting photos taken in the wrong orientation
• Creating diagonal compositions for social media
• Preparing images for print layouts
• Aligning scanned documents
• Generating thumbnails with creative angles

You can also flip images horizontally or vertically for mirror effects, or crop to remove unwanted rotated edges.
