Free Online Image Rotator
Photos taken on a phone held sideways, scanned documents that come out the wrong way, or graphics that just need flipping into the right orientation — LovePDFImg's Rotate Image tool fixes all of these in your browser with an instant preview. Click the rotate buttons as many times as needed until the image looks right, then download the result.
Rotation is handled with the Canvas API: the image is redrawn onto a canvas at the new orientation, swapping width and height for 90-degree turns. Because this is a simple repositioning of pixels rather than resampling, your image keeps its original sharpness. Nothing is uploaded — the entire process happens on your device.
