This brief tutorial will guide you in using The Gimp to resize pictures/images. It’s also a part of the Linux for Parents - A Beginners Guide to Ubuntu series. Though the Gimp is not a Linux specific program, it is included as the default image editing software in Ubuntu.

  1. Start by locating the image you want to resize. Right-click it and select Open With -> Open with “GIMP Image Editor”.
  2. resize images with gimp

  3. In the main Gimp window (the one with your picture displayed) select Image from the top menu, and then Scale Image… from the drop-down list.

  9. Now use the up or down arrow(s) in the Width: box to increase or decrease the size of your picture. In the example below, I’ve decreased the size of the picture by 50%. Click the Scale button when you’re ready.

  11. The picture will now shrink (assuming you opted to decrease its size).

  17. You’ll be asked what Quality you want the picture to be. The higher the quality, the larger the resulting file. I usually opt for somewhere around 85. Click OK when you’re done.
