Image Rotator — Free

Turn a photo 90°, straighten a crooked horizon by a tenth of a degree, or flip it — one image or a whole batch. In your browser, with nothing uploaded and no watermark.

Drop images here to rotate them

or choose them from your device. JPG, PNG and WebP — one or many at once.

Your images never leave this device. Rotation happens in your browser.

Most rotations are one of two things. Either the photo is simply the wrong way up — a scan that came out sideways, a picture taken with the phone turned — and the fix is one button. Or the photo is very nearly right, and a horizon sits a degree and a half off level, which is the sort of thing you cannot unsee once you have noticed it.

The first case is lossless: turning by 90° or 180° moves whole pixels to new positions without resampling anything, so the image content is untouched. The second needs interpolation, because rotating by 1.5° puts pixels between the ones that existed before — so it is done at high quality, and the alignment grid is there to make the right angle easy to find rather than guess at.

Rotating by a small angle also leaves empty triangles at the corners, and there is no universally right answer for what belongs there — so you choose: fill them, trim them away, or keep the original dimensions and let the overhang clip. Nothing is uploaded either way; the image is read and re-encoded entirely inside your browser.

How to rotate an image

  1. 1. Add your images

    Drag them onto the drop zone or choose from your device. Rotate one image or a whole batch at once — nothing is uploaded.

  2. 2. Turn or straighten

    Use the 90° and 180° buttons for an image that is simply the wrong way up. Use the Straighten slider for a crooked horizon, down to a tenth of a degree.

  3. 3. Decide what happens to the corners

    Rotating by anything other than a quarter turn exposes empty corners. Fill them with a colour, trim them away, or keep the original dimensions and clip.

  4. 4. Rotate and download

    Choose a format and quality, press Rotate, and download the result — individually or as a ZIP for a batch.

What to do with the corners

This choice only appears when you rotate by something other than a quarter turn, because that is the only time a rotated rectangle stops fitting its own box.

Frequently asked questions

How do I rotate an image for free? +

Drop the image above, press the 90° left or right button, and download the result. There is no account, no batch limit and no watermark — the image is never uploaded, and rotation happens entirely in your browser.

How do I straighten a crooked photo? +

Use the Straighten slider, which covers −45° to +45° in steps of a tenth of a degree, and turn on the alignment grid. Line the horizon or a vertical edge up against a grid line and the correction becomes obvious — most crooked photos need somewhere between half a degree and three degrees.

Does rotating an image reduce its quality? +

A quarter turn — 90°, 180° or 270° — moves pixels to new positions without resampling them, so the image content is unchanged. Rotating by any other angle does require resampling, since pixels no longer land on a whole-pixel grid; the tool uses high-quality interpolation to keep that as sharp as possible. Separately, re-encoding to JPG or WebP is lossy, so set Quality to Maximum, or choose PNG, if you want the result to be as close to the original as possible.

What happens to the corners when I rotate by a small angle? +

A rotated rectangle no longer fits its original box, so triangular gaps appear at the corners. You have three choices. Fill grows the canvas so nothing is clipped and paints the gaps in a colour you pick (or leaves them transparent for PNG). Trim crops back to the largest rectangle made entirely of real pixels — no gaps, slightly smaller image. Keep size holds the original dimensions and clips whatever falls outside them.

Can I rotate several images at once? +

Yes. Add as many as you like and they all receive the same rotation, straightening and flip. Download them individually or as a single ZIP. This is the quick way to fix a batch of photos that all came off a camera or scanner in the same wrong orientation.

What is the difference between rotating and flipping? +

Rotating turns the image around its centre — the content is the same, viewed from a different angle. Flipping mirrors it, which reverses left and right (or top and bottom). A flipped photo is not the same image turned around: any text in it reads backwards. Both are available here, and they can be combined.

Will this fix a photo that displays sideways on one device but not another? +

Yes. That happens when a photo carries an EXIF orientation flag that some apps honour and others ignore, so the pixels themselves are sideways. Rotating here writes the correct orientation into the actual pixel data, so the image looks right everywhere rather than depending on the viewer.

Are my images uploaded anywhere? +

No. Every image is read, rotated and re-encoded entirely inside your browser. Nothing is transmitted. That makes it safe for anything you would not upload to an unknown server — ID photos, document scans, private pictures. Once the page has loaded it works offline.

Is there a file size or batch limit? +

No fixed limit. Images are processed one at a time, so a large batch takes longer rather than failing. The practical ceiling is your device's memory on very large photos.

Will there be a watermark on the rotated images? +

No. The output is your image, turned, and nothing else added. There is no watermark, no badge, and no paid tier that removes one.
