How to rotate an image 90 degrees or flip it as a mirror image

Open Rotate image, choose the picture and tap Rotate right (90° clockwise), Rotate left (90° anticlockwise) or Turn 180°. To mirror it, tap Flip across; to turn it upside down as a reflection, tap Flip over. Then download.

Steps

1. Open Rotate image and choose an image. The turn and flip controls are ready under Turn and flip.
2. Tap the button you need. Taps add up: two taps on Rotate right make a half turn.
3. For a tilted photo, use the Angle slider under Any angle, or the presets -5°, -2°, 0°, +2° and +5°.
4. Pick a format under Save as: JPG, PNG or WebP.
5. Download. Undo steps back through each change before you save.

Which button does what

Turn 180° and Flip over look alike at first glance but are different: a turn keeps writing readable upside down, a flip makes it read backwards.

Rotate or flip a selfie

Front cameras often save a selfie the way others see you, while the camera screen showed you a mirror. If the photo looks "wrong" to you, that is why. Flip across gives you the mirrored version you saw while taking it. Be aware that any writing in the photo, such as a T-shirt slogan or a sign, will then read backwards.

Does rotating lose quality

Quarter turns, half turns and flips move pixels without blending them, so the picture itself is not softened. What can change quality is the save:

• JPG compresses again when you save. Choose a high quality under Save as if you will edit the file more.
• PNG saves without any loss, at a larger file size. A good choice for screenshots and graphics.
• WebP gives smaller files than JPG at similar quality, but some older programs cannot open it.

A fine angle, unlike a quarter turn, has to blend neighbouring pixels slightly. Every rotation tool does this.

Sizes, scale and social formats

The same panel has a Size group. Scale shrinks the saved picture by a percentage, and Fit a social size crops and sizes it to a platform format, such as an Instagram portrait post or a YouTube thumbnail. Pictures are never enlarged here.

Rotating many pictures

The page works on one picture at a time. For a PDF whose pages are sideways, use Rotate PDF instead, which turns pages without turning them into images.

Questions

How do I rotate a picture 90 degrees?

Tap Rotate right for clockwise or Rotate left for anticlockwise, then download.

How do I flip an image horizontally?

Tap Flip across. It swaps left and right, like a mirror.

Can I rotate by 30 degrees?

The Angle slider goes up to 45° either way in half-degree steps, so 30° is possible. The picture is zoomed in just enough to hide the corners, which trims more of the edges at larger angles.

Is my image uploaded?

No. The image is turned in your browser and stays on your device. Saving also leaves out most hidden metadata, such as the GPS position.
