What is true about saving transparency layers in a .jpg file?

Transparent layers cannot be saved in a .jpg file because the JPEG format does not support transparency. When an image is saved as a JPEG, all transparent areas are filled with a solid color, typically white or black, depending on the software settings. This limitation is inherent to the JPEG format, which is designed primarily for photographs where transparency is not typically required.

As a result, if an image containing transparency is saved as a JPEG, the transparent portions will be rendered fully opaque, resulting in a loss of the intended appearance. This makes JPEG unsuitable for graphics that utilize transparency, such as logos or images requiring a clear background to blend seamlessly into different contexts.

This foundational understanding of file formats is crucial for graphic designers, who must choose appropriate formats based on the needs of their projects. Knowing that JPEG does not accommodate transparency allows designers to select alternative formats like PNG or TIFF when transparency is necessary.
