A bitmap file is characterized by its direct storage of pixel information, meaning each pixel in the image is represented individually within the file. This method allows for a detailed representation of images, making bitmap formats ideal for rich photographic images. Each pixel has a defined color value, leading to higher fidelity in rendering images, which is a fundamental quality of bitmap files.

In contrast, while some bitmap formats can support transparency, it is not a defining characteristic of all. Bitmap files do not utilize lossy compression; rather, they often employ lossless compression or none at all, preserving the image quality. Lastly, bitmap files are not optimized for vector graphics, which are based on mathematical expressions to define shapes and lines, unlike bitmaps that rely solely on pixel representation. Thus, the statement about storing pixel information directly captures the essence of a bitmap file's unique features.
