About Rotate Image
Rotate Image turns a picture by a quarter, a half or three-quarters of a turn. The three fixed angles cover the overwhelmingly common case, which is an image that was taken or scanned in the wrong orientation and simply needs to be stood the right way up.
The output canvas is sized to fit the rotated image, so a quarter turn produces a canvas with the width and height exchanged. Nothing is cut off at the corners and no empty space is introduced, which is the behaviour you want when correcting orientation — a rotation that clipped the edges would be worse than no rotation at all.
The angles are applied as clockwise turns, so the quarter turn rotates the image to the right and the three-quarter turn gives the equivalent quarter turn to the left. Only these three angles are available, which keeps the result pixel-exact: an arbitrary angle needs interpolation and gently softens the whole image, so it is offered separately rather than being the default here.
The set of angles is closed and there is nothing else on the page to configure. An arbitrary angle cannot be typed in, so straightening a photographed horizon is out of scope, and there is no way to combine a rotation with a simultaneous flip or transpose — the mirrored result that a scan sometimes needs has to be produced by a separate operation. Because the three available turns are all right angles, no resampling occurs at all, but that also means no interpolation option or output-quality setting is offered since neither would have any effect. The canvas is written out as a PNG with no choice of format or compression, and very large images are limited by what the browser can hold in memory rather than by anything the tool enforces.
How to use Rotate Image
- 1 Choose the image that needs rotating.
- 2 Select the angle: a quarter turn, a half turn, or three-quarters.
- 3 Download the result, whose canvas dimensions swap for the odd quarter turns.
Frequently asked questions
Which way does the quarter turn go?
Clockwise, which is to the right. The three-quarter option gives the same result as a quarter turn to the left, so either way of thinking about it reaches the same angle.
Will anything be cut off at the corners?
No. The output canvas is sized to the rotated image rather than to the original, so the whole picture survives the turn. For a quarter turn that means the width and height of the result are the swapped originals.
Can I rotate by an angle of my own?
Not here — this tool deliberately offers only the right-angle turns, which avoid the interpolation that softens the image. A separate arbitrary-angle rotation tool handles free angles when you need to straighten a horizon.
Does rotating change the file format?
The result is written as a PNG regardless of what you uploaded. Quality is preserved exactly because PNG is lossless, though the file may be larger than a compressed original.

How Rotate Image behaves in detail
These are the specifics of this implementation — the exact ranges, defaults and fixed settings you are working with.
| Parameter | Value |
|---|---|
| Angles offered | 3 fixed choices — 90, 180 and 270 degrees, with 90 as the default |
| Canvas handling | width and height are swapped for the 90 and 270 cases, so the turned image fits the new frame without being cropped |
| Direction | a positive rotation is applied to the canvas context, which turns the image clockwise on screen |
| Output format | PNG at the rotated dimensions |

What Rotate Image does not do
Knowing the edges of a tool saves more time than another list of its features. These are the cases where it will not do what you might expect.
- Only quarter turns exist. There is no arbitrary angle, no fine adjustment and no straightening guide, so a scan that is tilted by a couple of degrees cannot be corrected on this page at all.
- Nothing is padded and no background colour is added: the canvas is resized to fit the turned image exactly, so the original frame size cannot be kept and the new corners cannot be filled with a chosen colour.
- The rotation is baked into the pixels, so it cannot be undone later by reading the file back — and because the output is always PNG, the source compression is replaced in the same pass.
