Ubuntu/Nautilus Bulk Image Resize

On lots of occasions I find my self doing bulk image resizing normally because I like to take phones with high resolution for my image collection but if I want to use them on the web I need to reduce their size. Introducing the Nautilus Image Converter I will be explaining how to install and use this extension in Ubuntu.

What is Nautilus Image Converter?
It’s an extension to mass re-size or rotate images relying on ImageMagick’s convert tool.

In Ubuntu open up the software center and type nautilus-image-converter into the search window and you should see the package we want listed in the window. [See figure below]

Figure 1

Click install enter your password if prompted and let Ubuntu weave its magic. Now to use this fabulous extension you will have to restart Nautilus and to do this with out having to log out open up your terminal and type

nautilus -q


killall nautilus

If Nautilus doesn't automatically reopen try this from the Unity menu (press the Super key) or using the run command (Alt+F2) Type in "gksudo nautilus" and click on Run to execute the command.

Ok so now we should have the Nautilus Image Converter installed and ready to use so navigate to the directory containing the images you wish to re-size. Next select all the images you want to re-size and right click you should now see two new entries in the option list Re-size Images and Rotate Images. [See Figure Below]

Scroll down and select Re-size Images you will be confronted with a re-size image options window. [See Figure below]

Figure 3

You have two main option the first is Image Size here you can choose the following methods of resizing.

  • Select a size from the predefined option list I normally use this.
  • Scale the images by percentage the default value is by 50%.
  • Select a custom size (Make sure you scale proportionally).

The next section is related to the file name given to the re-sized images if you want to keep the originals select some text to be appended to the end of each image but if don't need the originals select Re-size in place. When you are happy with your settings hit Re-size and wait to be amazed.

You should now have a bunch of re-sized images ready to be used in what ever project you are working on. If you need to do a bulk re-name of images or files check out my guide in the doc's section.
