Correct upside-down phone photos or create mirror-image graphic layouts with our free Image Flip & Rotate Tool. Rotate JPEG, PNG, or WebP files by 90° or 180° increments or specify custom arbitrary angles (-180° to 180°). Toggle horizontal or vertical mirror flips with live visual canvas rendering. The client-side transformation engine recalculates dynamic bounding boxes and exports transformed images in PNG, JPEG, or WebP format with zero server uploads.
Drag and drop your image file onto the upload area or click to browse files from your device.
Use the +90°/-90°/180° rotate buttons, horizontal/vertical flip toggles, or custom angle slider to adjust photo orientation.
Choose your target output format (PNG, JPEG, or WebP), click Apply Transforms, and download your modified photo.
Quickly fix sideways photos or create mirrored graphic reflections with one-click rotation and flip controls.
Adjust photo tilt using the -180° to 180° angle slider while automatically expanding canvas bounding dimensions to prevent clipping.
All affine matrix transformations execute inside your browser sandbox. Your images are never transmitted over a network or stored on servers.
Image orientation modifications use 2D affine transformation matrices in linear algebra. In an HTML5 Canvas 2D context, operations like rotation (ctx.rotate(rad)) and scaling (ctx.scale(sx, sy)) manipulate the underlying coordinate space matrix. Mirroring horizontally applies a scaling matrix of sx = -1, sy = 1 around the origin, while vertical flipping applies sx = 1, sy = -1.
When rotating an image by arbitrary angles (other than 0° or 180°), the rectangular dimensions of the output canvas must expand to accommodate the rotated corners without cropping. The bounding box dimensions are calculated using trigonometry: $W_{\text{new}} = W \cdot |\cos(\theta)| + H \cdot |\sin(\theta)|$ and $H_{\text{new}} = W \cdot |\sin(\theta)| + H \cdot |\cos(\theta)|$. The canvas context origin is translated to the center ($W_{\text{new}} / 2, H_{\text{new}} / 2$) before applying rotation matrices, ensuring perfect centering and zero clipping.
Executing transformations directly on client-side canvas contexts guarantees zero quality degradation during 90-degree steps and eliminates round-trip latency. Flipped and rotated files can be exported to uncompressed PNG or compressed JPEG and WebP formats, providing complete control over image formatting and local file privacy.
