Rotate or flip an image
Phone photos often arrive sideways because the rotation lives in EXIF metadata rather than the pixels, and not every theme respects it. Rotating here bakes the correct orientation into the image itself, so it looks right everywhere.
Common questions
Why does my photo look sideways in WordPress?
The camera stored the orientation as EXIF metadata instead of rotating the pixels. WordPress usually honours it, but some themes, email clients and social previews do not. Rotating the pixels removes the ambiguity.
Does rotating re-compress the image?
Yes — the image is decoded and re-encoded, so there is a small quality cost on JPEG. Keep the quality slider high if the file is going to be edited again later.
