Image Rotator
Fix a sideways or upside-down photo, or straighten a tilted horizon — rotate to any angle, or snap to 90° steps.
How to Rotate an Image
- Click the upload area or drag in a JPG, PNG, or WebP image.
- Drag the Angle slider to rotate to any degree from -180° to 180° — great for straightening a tilted horizon.
- Or use "Rotate Left 90°", "Rotate Right 90°", "Flip 180°" for quick corrections, and "Reset to 0°" to start over.
- Watch the live preview — the canvas automatically resizes to fit the full rotated image at any angle.
- Click "Download Rotated Image" to save the result in the same format as your original upload.
Frequently Asked Questions
Does rotating my image reduce its quality?
Rotating in exact 90 degree steps doesn't resample or blur any pixels, since the tool simply redraws the canvas at a new angle. Free-angle rotation (anything not a multiple of 90) does require the browser to interpolate pixels along the tilted edges, which introduces a small amount of softening - that's unavoidable with any rotator at an arbitrary angle. If you uploaded a JPG or WebP, the download is also re-encoded at 92% quality during export, which introduces the same small amount of compression any JPEG/WebP save does.
Why did the canvas size change after I rotated?
The tool automatically resizes the canvas to the bounding box of the rotated image so nothing gets cropped off - a 1200x800 photo becomes exactly 800x1200 after a 90 degree rotation, and at in-between angles like 15 or 40 degrees the canvas grows to fit the full tilted rectangle, with transparent (or white, for JPG) fill in the corners.
What file format is my downloaded image?
The output matches your upload: JPG stays JPG, WebP stays WebP, and everything else (including PNG) is saved as PNG. Transparent PNG or WebP backgrounds are preserved; JPG output gets a white background fill since JPEG can't hold transparency.
Can I rotate by a custom angle, like 15 degrees?
Yes - drag the Angle slider to any value from -180° to 180° for free rotation, in addition to the 90°, 180°, and 270° quick-rotate buttons for the common case of a sideways or upside-down photo. The canvas automatically resizes so the full rotated image always stays in frame.
Is my photo uploaded to a server to be rotated?
No. The rotation happens entirely in your browser using the Canvas API's rotate transform - the image file never leaves your device.
