- Native format of the Krita painting program, developed by the Krita Foundation.
- Description
- The UPI file format is associated with Ulead PhotoImpact, an image editing software developed by Ulead Systems. It serves as a project file that contains various elements of a photo editing project, including images, text, and effects. This file format allows users to save their work in progress and return to it later, maintaining the ability to edit individual elements without starting from scratch. UPI files are proprietary to the PhotoImpact software, which was widely used for digital photo editing, graphic design, and web page creation before being acquired by Corel.
- Image file saved by the Krita painting program. A Krita file is a zip archive holding the full layer stack: each layer's pixel data as compressed tiles, its name, position, opacity, blending mode and visibility, plus a merged preview of the whole image.
