Rotation
Quarter turns swap width and height and make orientation explicit in the pixels
A 90-degree left or right rotation changes a landscape canvas into portrait dimensions, while 180 degrees keeps the same width and height. This can resolve files that rely on an EXIF orientation tag that another app ignores. Check the downloaded image in the destination because viewer behavior around orientation metadata can differ.
Flipping
A horizontal flip mirrors meaning as well as composition
Mirroring can improve visual direction or correct a reversed camera preview, but it also reverses text, logos, traffic signs, uniforms, and asymmetrical products. Vertical flipping is less common and turns the frame top-to-bottom. Use Reset All when experiments make the intended orientation uncertain.
Batch use
Apply shared corrections only to files with the same orientation problem
Scanned pages from one feeder or a camera sequence may share a wrong rotation and benefit from batch controls. Mixed phone photos may not. Review thumbnails, separate exceptions, and open several exports before downloading the ZIP. Preserve originals when orientation history or metadata matters.
