A CR3 file is an image created by select Canon digital cameras, such as the EOS M50 and EOS R. It may store uncompressed RAW image data exactly how it was captured by the CCD or compressed RAW (C-RAW) image data depending on the camera setting selected. CR3 files were introduced in 2018 with the release of the Canon EOS M50, replacing .CR2 files.
Adobe Encapsulated PostScript Interchange Format (EPI) is a vector image file format used to store and interchange vector graphics and text. It is an extension of the popular Encapsulated PostScript (EPS) format and is used as a container for bitmap images and other data. EPIs are used for high-resolution printing and digital publishing.
