Image Rotator
Rotate images by 90, 180 or 270 degrees.
Lower quality gives a smaller file.

Thanks for the feedback!
The Image Rotator turns a picture 90 degrees clockwise and saves the result as a PNG, swapping its width and height. It fixes photos that were shot sideways, scans fed into the scanner the wrong way, and pictures that look upright on your phone but appear on their side after uploading to a website.
Getting 90, 180 or 270 degrees
Each click of Process image turns the image you loaded a quarter-turn clockwise. There are no angle options, and clicking again produces the same quarter-turn of the original, not an extra one. For bigger turns, download the result, load that file back in and rotate again:
| You want | Passes needed |
|---|---|
| 90° clockwise (a quarter-turn right) | 1 |
| 180° (upside down) | 2 |
| 90° anticlockwise (270° clockwise) | 3 |
Quarter-turns move pixels to new positions without recalculating them, and PNG is lossless, so rotating several times does not blur the picture.
What changes in the rotated file
- Dimensions swap. A 1920 × 1080 landscape image becomes 1080 × 1920 portrait. The Result label confirms the new size before you download.
- Format becomes PNG. Every rotation is saved as PNG, so a camera JPG will grow noticeably in size. Convert it back with PNG to JPG if you need a compact file. The Quality slider does not apply here.
- Transparency survives. Transparent areas of a PNG stay transparent.
- Metadata is not copied. Details such as the date taken and GPS location are left out of the new file.
Why photos turn sideways after uploading
Phone cameras often store the image data in the sensor's native landscape layout and add an "orientation" tag (part of the EXIF metadata) telling apps how to display it. Your gallery reads the tag and shows the photo upright, but some older software and upload systems ignore it and show the raw, sideways pixels.
Modern browsers apply that tag when they display and process an image, so the Original preview here shows the photo the way your phone does, and that is the orientation the tool rotates from. The saved PNG has the rotation built into its pixels and carries no orientation tag, so it looks the same in every app, however old.
Tips for common jobs
- Scanned documents: rotate before running text recognition; OCR engines read upright text far more reliably.
- Portrait photos for landscape slots: rotating changes which way the picture faces; to change the shape without turning it, crop instead.
- Mirror-image problems such as backwards text in a selfie are not fixed by rotation; that needs a flip.
- PDF pages should be rotated with the PDF rotator, which keeps them as PDF instead of converting them to pictures.
Everything happens inside your browser, and the image is never uploaded.
