offers a JPEG (Joint Photographic Experts Group) file format (JPG) which provides
for a compressed file format. The JPG file compression is irreversible. The
compression ratio shall not exceed 10:1 and is identified in the lower left-hand
corner as “10:1 Q:12”.
BMP and TIFF images do not have the compression label applied when they are
created. If either one of these formats is later exported to JPG, the compression
label is applied to the new JPG file. If a JPG file is exported to BMP or TIFF
format, the BMP or TIFF will show the compression label because it was applied
to the JPG when it was created. Even though BMP and TIFF are not compressed,
the converted JPG still has loss and the label will identify this loss.
