What is BMP bad for?

Bitmap files, however, do have drawbacks: They can be very large, particularly if the image contains a large number of colors. Data compression can shrink the size of pixel data, but the data must be expanded before it can be used, and this can slow down the reading and rendering process considerably.

Can an IMG file contain a virus?

JPEG files can contain a virus. However, for the virus to be activated the JPEG file needs to be ‘executed’, or run. Because a JPEG file is an image file the virus won’t be ‘released’ until the image is processed.

Which is better JPEG or BMP?

Is BMP better than PNG?
