Rotate Image

Turn photos by quarter turns or any exact angle. Several images can be rotated together and downloaded as a ZIP.

Quarter turns and custom angles

The quick buttons rotate by -90, +90 or 180 degrees, and you can press them repeatedly. For anything else, type an angle from 0 to 360 or drag the slider. Positive values turn the image clockwise.

The same angle is applied to every image in the list, which is handy when a whole set of phone photos came out sideways.

What happens to the corners at odd angles

A rectangle turned by, say, 10 degrees no longer fits in its original frame. Instead of cutting off the corners, the tool enlarges the canvas to the smallest rectangle that holds the whole rotated picture. The four triangles this creates are empty:

  • In PNG and WebP they are transparent.
  • In JPG, which is the default here and cannot store transparency, they come out black.

To straighten a slightly tilted horizon without visible corners, rotate, save as PNG, and then crop inwards with the Crop tool.

Quality of rotated images

Quarter turns move pixels without blending them. Any other angle has to resample, because pixels no longer line up with the grid, so a slight softening is normal. Rotating the same image many times by small angles adds up; it is better to rotate once from the original by the total angle you want.

Output is saved at quality 0.92 for JPG and WebP. PNG is lossless.

Sideways phone photos

Phones often save a photo sideways and add an EXIF orientation tag telling viewers to turn it. Browsers apply that tag when they display the image, and this tool works from what the browser displays, so a photo that looks upright in the preview will be saved upright. The saved copy has no EXIF data, so it will not be turned a second time by other apps.

Batch download

One processed image downloads directly with -rotated added to its name. Two or more are packed into rotated-images.zip in your browser.

Where the processing happens

Rotation runs on a canvas in your browser, image by image. Nothing is uploaded. HEIC appears in the file picker but can only be read in browsers that support HEIC, normally Safari.

Questions about this tool

Why are there black triangles in my rotated JPG?

The canvas was enlarged to fit the rotated image and JPG cannot store the empty corners as transparent. Save as PNG or WebP, or crop the corners away.

Does rotating by 90 degrees reduce quality?

The rotation itself does not, but saving as JPG or WebP re-encodes the image at quality 0.92. Choose PNG if you need the result to stay lossless.

My phone photos are sideways. How do I fix them all at once?

Add all of them, press the 90 degree button in the direction you need, and download. The same turn is applied to every photo, and two or more come as one ZIP file.

How do I straighten a slightly crooked horizon?

Type a small angle, such as 2 or 358, until the horizon looks level. Save as PNG so the new corners stay transparent, then crop them away with the Crop tool.

Which way does a positive angle turn the picture?

Clockwise. To turn it anticlockwise by a few degrees, use an angle just below 360, for example 355.

My photo looks upright here but sideways in another app. Will the download be right?

Yes. The tool saves the photo the way it looks in the preview, and removes the orientation tag, so other apps will not turn it again.
