PixiEditor is a 2D graphics editor for pixel art, painting, vector work and animation. It offers a dedicated pixel-art toolset with advanced palette management and a pixel-perfect pen mode, and supports frame-by-frame animation. It is aimed at game developers, illustrators and hobbyists who create sprites, icons or logos. According to the project's website it is a desktop application that works offline; it can be downloaded directly and is also available through the Microsoft Store, Steam and Flathub.
PixiEditor is developed by Pixi Labs Sp. z o.o., a Polish company in Międzyświeć. The source code is published on GitHub under the LGPL-3.0 licence, so you can inspect and build the software yourself. Because it runs locally on your own computer, your files stay there as well; the project's website describes no mandatory cloud service or account. The website does offer a newsletter sign-up that asks for an email address. For European organisations it is an open-source alternative to commercial pixel-art editors from outside Europe.
