Final answer:
The only image format that you can't compress is a Bitmap (BMP) format.
Step-by-step explanation:
The only image format that you can't compress is a Bitmap (BMP) format.
Compression is a process of reducing the file size of an image by removing unnecessary information. Most image formats, including JPEG, use compression to create smaller files. However, the Bitmap format is an uncompressed format where each pixel in the image is represented by a separate element in the file. This lack of compression results in larger file sizes compared to compressed formats like JPEG.
For example, if you have a photograph saved in BMP format, it will take up more space on your device compared to the same photograph saved in JPEG format.
