 225 <p>We list a few examples of the <kbd>mogrify</kbd> command here to illustrate its usefulness and ease of use.  To get started, lets reduce the size of our

 236   </a>
 237 </p>
 238
 239 <p>You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command:</p>
 240
 241 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -resize 256x256 *.jpg</span></p>
 242 <p>Finally, we convert all our PNG images to the JPEG format:</p>
 243
 244 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -format jpg *.png</span></p>
 245 <p>Here image files 1.png, 2.png, etc., are left untouched and files 1.jpg, 2.jpg, etc., are created.  They are copies of their respective PNG images except are stored  in the JPEG image format.</p>
