 195 </p>
 196
 197 <p>You can resize all your JPEG images in a folder to a maximum dimension of 256x256 with this command:</p>
 198
 199 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -resize 256x256 *.jpg</span></p>
 200 <p>Finally, we convert all our PNG images to the JPEG format:</p>
 201
 202 <p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>mogrify -format jpg *.png</span></p>
 203 <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>
