GIMP is a free and open-source raster graphics editor used for image retouching and editing, free-form drawing, converting between different image formats and more specialized tasks. GIMP stands for GNU Image Manipulation Program.
GIMP is often considered as the biggest rival to Adobe Photoshop and is the most popular image editing application for Linux. In terms of functionality, it is very similar to Adobe Photoshop but has a different user interface. It is available for Linux, macOS, and Microsoft Windows.
It is primarily developed by volunteers as a free software project associated with both the GNU and GNOME Projects. Though it is very useful, it feels very barebones without GIMP plugins.
One can utilize it to its extreme limit without installing plugins for GIMP. Saying so, huge numbers of plugins for GIMP are available on the web which makes it very difficult and confusing to decide which one to download and which one to avoid.
