Some languages are better suited for some tasks than for others.

imagedata = imread('YourImage.jpg');
imwrite(imagedata, 'YourNewImage.tif'); %can even change the image type

imwrite(uint8([156 176 187...]...)
If you used [156 176 187...] then the data class would be "double" (because that is the default for MATLAB), and that would be a problem, as MATLAB assumes that "double" values should have a range of 0 to 1 for images.
