Why a photo looks sideways in one app and not another
Cameras rarely rotate the pixels. They record the picture as the sensor saw it and add an EXIF orientation tag saying which way up it should be shown. Software that reads the tag shows it correctly; software that ignores it shows it on its side.
Rotating here moves the actual pixels and writes the result without the tag, so the image looks the same everywhere — including in the upload form that was showing it sideways.
Straightening a tilted horizon
A few degrees is usually all a wonky horizon needs. Turning by anything other than a multiple of 90° leaves triangular gaps at the corners, so the result is either padded or cropped in slightly — a small tilt costs a small crop.
Rotating by 90°, 180° or 270° costs nothing at all: the pixels are rearranged, not resampled.
Flipping is not rotating
A flip mirrors the image; a rotation turns it. They look similar on a symmetrical subject and completely different on anything with text in it — a mirrored sign is unreadable. Mirroring is what you want for a selfie that came out reversed, or to make a subject face into the page rather than off it.
Frequently asked questions
Why does my photo appear sideways only on some devices?
It carries an EXIF orientation tag rather than being rotated in the pixels. Apps that read the tag look right; apps that do not show the raw sensor orientation. Rotating here removes the ambiguity.
Does rotating lose quality?
Not at 90, 180 or 270 degrees — the pixels are simply moved. Any other angle has to resample them, which softens the image very slightly. Saving a JPG also re-encodes it once.
Can I rotate by a few degrees to straighten a horizon?
Yes. Expect a small crop or transparent corners, because a rotated rectangle does not fill the original frame.
Will it strip my location data?
Yes — the saved file is written fresh, so EXIF including GPS is not carried over. That is usually welcome; if you needed the metadata, keep the original.
