The pre-requisities

This is a BEGINNER workflow explainer, so you just need to install and open the software. We’ll take it from there.

If you’re new to IT / computing, you may need help downloading and installing the software. Start with a search for ‘how do i install gimp’ or speak with someone who’s familiar with downloading and installing.

Why would I do this?

Being able to resize images is an essential part of many image-editing workflows. In this explainer we open a large logo image and make it smaller, ready to use it on the web or upload to social media. Resizing is equally applicable to reducing file sizes or even to enlarge images to print or display at scale.

Let’s do it!

Good to know

The logo we’ve opened is in PNG format (often refered to as ‘ping’). This format is popular for logos as it supports transparency. Photos are commonly stored in .jpg (jpeg) format, which does not support transparency, or a ‘raw’ format which applies zero or little compression. Different camera manufacturers use their own versions of ‘raw’, and most non-photographic software (E.g. Microsoft Office) does NOT directly support it.

Where to next?

In the explainer we successfully resized the logo to make it smaller, but what if you need to make an image LARGER? Have a look at the additional options available on GIMP’s ‘Scale Image’ dialog:

Generally speaking, if you want to UPSCALE an image it’s best to use the CUBIC ‘quality’ option, and for downscaling it’s best to use the LINEAR quality option. Some software, including the latest versions of PaintShop Pro and Photoshop also offer AI (artificial intelligence) upscaling which can offer impressive results for images with ‘common’ content (E.g. Faces / buildings / landscapes). This feature is not currently available in GIMP.
