Rotate images online — fix sideways photos, straighten horizons, and more
Phones save photos sideways more often than they should. You hold the phone in landscape mode, take a shot, open it on your computer — and it's rotated 90 degrees. Some apps handle the EXIF orientation data correctly and display it right; others ignore it entirely and show the raw file. The simplest fix is to rotate the image itself and save a corrected copy. That way it displays correctly everywhere, regardless of what the viewing software does with metadata.
This tool handles the job in your browser with no upload. Select your images, pick a rotation angle, click Rotate — done. It supports batch rotation, so if you have 30 photos from a shoot that all need a 90° clockwise fix, you can do them all at once and download a ZIP.
90° CW, 90° CCW, and 180° — which one do you need?
90° clockwise (CW) rotates the image to the right. If your photo looks like it was taken with the phone tilted to the left — the subject appears lying on their right side — 90° CW fixes it. 90° counter-clockwise (CCW) is the opposite: use it when the subject appears to be lying on their left side. 180° flips the image upside down, which is less common but useful for certain scanning workflows or fixing inverted images.
A quick trick: open the photo on your phone, hold the phone sideways in the orientation that makes the photo look correct — that tells you exactly which rotation you need. If you have to tilt your head right to read the photo, you need 90° CCW. If you tilt left, 90° CW.
Custom angle rotation — straightening crooked photos
The custom angle slider runs from -180° to +180°. For straightening a slightly tilted photo, you typically need small adjustments: -3° to correct a horizon that drifts up to the right, +2° for one that drifts up to the left. Drag the slider and watch the preview update to find the right amount.
For non-90° rotations, the canvas expands to fit the rotated image and the exposed corners fill with the background color you select (white by default). After a custom rotation, there will be white triangular corners. The next step is usually to crop those out — use a freehand crop and trim just inside the white edges. The result is a straight, clean photo with no artifacts.
Does rotating a JPG reduce quality?
For 90° and 180° rotations, the quality impact is minimal. The only loss comes from re-encoding as JPEG at the end — which is why the quality slider is there. At 90% quality (the default), the difference between the original and the rotated version is invisible in practice. Set it to 100% if you're working on something where every pixel matters.
PNG output is lossless regardless of quality setting — rotating a PNG and saving it back as PNG loses nothing. WebP follows the same rules as JPG for lossy output.
Custom angle rotations have one additional quality consideration: the rotation uses bilinear interpolation to calculate the color of pixels that fall between the original pixel grid. This can softly blur fine detail at very small scales. For photos it's imperceptible. For images with very sharp text or pixel-art, you'd notice it at 100% zoom — but for anything larger than a thumbnail at normal viewing distance, it won't be visible.
Batch rotation — rotating multiple images at once
Select multiple images in the file picker (or drag and drop several at once) and they'll all be added to the queue. Set your rotation once and click Rotate Images — all queued files are processed with the same settings. Download them individually or grab the ZIP. This is handy for bulk corrections after a photo session, or fixing a folder of scanned documents that all came out in the wrong orientation.
If you need to flip images as well as rotate them — mirror horizontally or vertically — the flip tool handles that as a separate step. You can also resize the rotated images afterward if you need them at a specific dimension. Each tool is fast enough that chaining them takes less time than finding a desktop application that does all of it. For adjusting brightness, contrast, or adding filters after rotation, the photo editor covers all of that without re-uploading your original. Rotation and flipping are often the first corrections you make to a photo before any other editing — getting orientation right first means every subsequent adjustment is working with the image the right way up.
