What file type are bitmap images?

Bitmap images, also known as raster images, are made up of a grid of individual pixels, each of which has its own color and intensity. The correct file types associated with bitmap images include JPEG, GIF, PNG, and TIFF.

JPEG is commonly used for photographs and web images due to its efficient compression, which reduces file size while sacrificing some image quality. GIF is popular for simple animations and images with limited color palettes, while PNG supports transparency and is often used for images that require a transparent background. TIFF is a versatile format that can store images with high detail and color depth, making it ideal for professional printing and archiving.

The other choices consist of vector formats, which are not bitmap images. Vector graphics are composed of paths defined by mathematical equations rather than pixels, allowing them to scale without losing quality. EPS, AI, and PDF files often incorporate vector properties; RAW, BMP, and WEBP primarily serve specific uses but are not as widely utilized as the formats mentioned in the correct answer. Therefore, the rationale behind identifying JPEG, GIF, PNG, and TIFF as bitmap image formats lies in their pixel-based composition and common usage in digital imaging.
