What is the function of the Free Transform command in Photoshop?

The Free Transform command in Photoshop is a powerful tool that offers a range of functionalities essential for editing and manipulating images. It allows users to apply transformations such as rotating, scaling, and skewing selections or layers. This flexibility is crucial for achieving precise adjustments to graphics and layouts.

When using Free Transform, users can click and drag to resize an image or layer by grabbing the corner handles while holding down the Shift key to maintain the aspect ratio. Additionally, the rotation can be accomplished by moving the cursor just outside a corner handle, which allows the image to pivot around its center. The skewing effect can be achieved by dragging the side handles. This command is particularly useful in graphic design and photo manipulation, enabling fine-tuning of dimensions and perspectives of objects within a composition.

The other choices address different functions that do not pertain to the capabilities of the Free Transform command. Adding text, merging layers, and saving changes permanently represent separate actions within Photoshop's extensive toolset, but they do not encompass the specific transformative functions associated with Free Transform.
