CR2 is a raw image file format developed by Canon for its digital cameras. It contains unprocessed image data from the camera's sensor, allowing for the highest quality and flexibility during post-processing. CR2 files are typically large but retain every detail of the original shot.
PNG is a lossless image format that supports transparency, making it ideal for logos, icons, and web graphics. Unlike JPEG, PNG doesn’t lose any image data during compression. It retains high-quality detail, especially in images with sharp edges, and is commonly used for design work where transparent backgrounds are required.
