Rotate or Flip Images Free

Phones rotate photos based on the orientation you took them. Mostly this works. Sometimes it doesn't, and you end up with a sideways photo on every device that didn't read the EXIF rotation flag.

This tool rewrites the actual pixels. Whatever device opens the file afterwards, it looks right. 90° clockwise, 90° counterclockwise, 180° flip, mirror — pick what you need. For non-90° angles, the canvas grows to fit the rotated image and the new corners get a transparent background (or white, if you're saving as JPG).

Batch rotate works on whole folders of photos. If they're all sideways the same way (common with one bad camera), one click fixes the lot.
