N = imfinfo('cameraman.tif').FileSize;
[num2sip(N),'B'] % SI prefix
ans = '65.24 kB'
[num2bip(N),'B'] % binary prefix
ans = '63.711 KiB'

Hi Pradeep,

Yes, it is possible to display the size of an image in MB or KB in MATLAB. You can achieve this by calculating its size based on the number of bytes it occupies in memory.

The image size can be calculated using the “imfinfo” function. The “FileSize” output argument of the “imfinfo” function returns the size of the file in bytes. More information about extracting metrics about a graphics file using the “imfinfo” function can be found in this link - https://www.mathworks.com/help/matlab/ref/imfinfo.html#:~:text=character%20vector-,FileSize,-Size%20of%20the.

Here is some sample code to find the size of a graphics file in MATLAB –

imageFilePath = 'path_to_your_image.jpg'; % Replace with your image file path
% Get the size of the image in bytes
info = imfinfo(imageFilePath);
imageSizeInBytes = info.FileSize;
% Convert bytes to KB and MB
imageSizeInKB = imageSizeInBytes / 1024;
imageSizeInMB = imageSizeInKB / 1024;
