What happens when pixels are removed and bitmap graphic files are compressed?

When pixels are removed from a bitmap graphic file during the compression process, the file size decreases because fewer pixels mean less data to store. Bitmap graphics, which consist of a grid of individual pixels, rely heavily on the information contained within these pixels to convey visual detail. As pixels are removed or compressed, the image effectively loses some of its data and detail, leading to a reduction in quality.

This loss of image quality can manifest in various ways, such as blurriness, loss of detail, or pixelation. Compression algorithms may prioritize reducing file size over maintaining high fidelity, which means the resulting image may not accurately represent the original. This connection between file size, image quality, and pixel count is crucial for understanding how bitmap graphics behave during compression processes.
