How rotating and resizing work
Lossless turns, resampling, empty cornersA photo is a grid of pixels lined up in rows and columns. Rotating turns that grid at an angle and copies it onto a new grid, while resizing changes the number of cells in the grid itself. That is why a turn in 90° steps only moves the cells and does not reduce quality on its own, whereas straightening by 0.1° has to calculate the values between cells.
Many phone photos are stood upright only by an orientation tag (EXIF) inside the file, so they can appear sideways or upside down on some devices. This tool reads the tag and rotates what you see, then turns the pixels themselves when saving, so the result looks the same on any device. Saving as JPG or WEBP compresses the file again, though, so the format can cause a small quality difference separate from the rotation.
