What Is Rotate & Flip?
Rotating turns an image around its center — the classic fix for a photo taken with the phone held sideways, or a scanned page that came out upside down. Flipping mirrors it left-right or top-bottom, useful for correcting a mirrored selfie or reversing a scanned image. Both are lossless: no pixel data is added or removed, just repositioned, so you can rotate and flip an image as many times as you need without any cumulative quality loss the way repeated JPEG re-saves would cause.
