jpgs in this folder and every sub folder contained within it (recursively) вЂ“ FIRST DO A TEST RUN! вЂ“ the following command will NOT change files, it will just output to console the commands that it would be performing: find. I used 2000000 which made all of my 4:3 photographs 1632Г—1224 and the panoramas similarly sized вЂ“ not totaly precise but at least now all the pictures taken by different cameras at different resolutions are all roughly the same size! Since many of my photos were different aspect ratios, different sizes and different orientations, some even panoramas, I settled for the above option. This will scale the images so that they contain X number of pixels. Whether it be 800Г—600 or 600Г—800 or even 1200Г—400 pixels in size the image contains a total of 480000 pixels.

To resize them to a specific pixel content (effectively scaling small images up and large images down to a uniform size while maintaining aspect ratio) of their original size do: mogrify -resize 480000 *. To resize them to 50% of their original size do: mogrify -resize 50 % *. To resize them to a specific size (distorting their aspect ratio if necessary) do: mogrify -resize 800 x 600! *. For instance once with *.jpg, then *.JPG, then *.jpeg then *.JPEG It is likely that you will have to run any of these commands for all file extention variations in your collection. jpgs in this folder to 800px wide do: mogrify -resize 800 *. Now for example, if you only need to resize the.

For example: cd /home/username/Pictures/toShrink Then you can cd (change directory) to the folder containing the pictures that are to be resized.

So today I needed to resize a photo archive of 3000 images spread out in sub-folders for every year and monthвЂ¦ Fortunately, in linux with a bit of research I got it!ДЇirst off, you must download ImageMagick вЂ“ if you are running Ubuntu, LinuxMint or a similar distro with APT you can simply do: sudo apt-get install imagemagick
