Types of rotation
Quarter turns swap the width and height, so a portrait shot displayed sideways is corrected without any loss of pixels. A 180-degree turn keeps dimensions the same and simply flips the image.
Free rotation covers small angles for straightening a tilted horizon. Because the edges no longer align to the pixel grid, the result is usually recomputed, which can soften it slightly.
Orientation stored as metadata
Phones often record an orientation flag instead of rewriting pixels, letting a viewer display the picture correctly while the stored grid stays as captured. Editors bake the rotation in when you save.
That distinction matters when sharing. Software that ignores the flag shows the picture sideways, which is why exports are sometimes flattened deliberately.
- Quarter turns preserve every pixel
- Free angles recompute edge pixels
- Orientation metadata can stand in for baked rotation
- Rotating and then cropping is a common sequence
Rotation and Filekind
Filekind does not offer an image rotation tool today. Its resize tool scales dimensions, and its PDF builder follows each image's shape with automatic page orientation, but neither turns an image.
Straighten or rotate the photo in an image editor first. The corrected file can then be converted or compressed in the browser, where nothing is uploaded. Quarter turns are the safest case to apply once, because they reuse the original pixels instead of recomputing the grid.
