How Image Rotator Works
Rotating and flipping are done by transforming the canvas before drawing the image onto it — the canvas is resized to fit the rotated result so nothing gets cut off. The 90°/180°/270° buttons and custom angle slider work together, and flips can be combined with any rotation.
How to Use This Tool
- Choose or drag in an image.
- Use the quick rotate buttons for 90°, 180° or 270° turns, or drag the slider for a custom angle.
- Select Flip Horizontal or Flip Vertical to mirror the image.
- Select Download to save the result.
Example
A photo taken sideways can be straightened with a single Rotate 90° click; a scanned document that's upside down needs Rotate 180°.
Helpful Tips
- Rotating by a custom angle (not a multiple of 90°) leaves diagonal edges — the canvas expands to fit the whole rotated image, with transparent corners for PNG output.
- Flip and rotate can be combined — for example, flip horizontally first, then rotate 90°, to mirror and reorient in one pass.
Frequently Asked Questions
Is my image uploaded anywhere?
No, rotation and flipping happen entirely in your browser using the Canvas API.
Will rotating a non-90° angle crop my image?
No — the canvas automatically resizes to fit the full rotated image, so no part of the picture is cut off.
What happens to the corners when I rotate by a custom angle?
For PNG downloads, the new corners are transparent. For JPEG, since JPEG doesn't support transparency, they'll appear white.
