Rotating and flipping images instantly
Upload an image, then rotate it 90° at a time in either direction, or flip it horizontally or vertically - each click updates the preview instantly. Combine rotations and flips as needed (rotate twice for 180°, or rotate and flip together for a mirrored diagonal result), then download the finished image. Everything happens locally in your browser using the HTML5 canvas; your image is never uploaded to any server.
Why 90-degree rotation and flips, specifically
The overwhelming majority of real-world "my image needs fixing" situations are a photo that's sideways or completely upside-down (needing a clean 90° or 180° rotation) or a mirror-image flip issue common with front-facing camera photos. Covering those cases with exact, lossless 90-degree increments handles nearly every practical need without the complexity of an arbitrary-angle rotation interface.
Why there's no quality loss
A 90-degree rotation or a flip simply repositions each existing pixel to a new location in the grid - it never has to calculate a new color by blending neighboring pixels together the way an arbitrary-angle rotation does. That resampling step is exactly where quality loss (blurring at edges) comes from in image editing, and this tool's operations never touch that step at all.
When you need more than this tool offers
For an arbitrary angle - straightening a photo that's tilted by, say, 7 degrees rather than a clean 90 - a full photo editor with fine-angle rotation and resampling controls is the right tool, since that kind of rotation inherently requires some quality trade-off that this tool's lossless approach doesn't attempt.
