Hi, @saeed hassiny.

Use below code.

clc

clear all

%% Get the info

cd 'Images'

img_dir = dir('*.pgm');

cd ..

len_img = length(img_dir);

fileFmt = '.jpg'; % new file format

for i = 1 : len_img

% get the image one by one.

f = img_dir(i).name;

cd 'Images'

% read image

f1 = imread(f);

cd ..

% extracting file format

[pathstr, name, ext] = fileparts(f);

if strcmp(ext, '.pgm')

% Concatenate with new file format

imgCat = strcat(name, fileFmt);

cd 'NewImages'

% writing into new location

imwrite(f1,imgCat);

cd ..

end

end
