CRW to PNG
File Converter

CRW was one of the early raw image file formats used by Canon digital cameras. It captures all the data from the camera’s sensor without any compression or processing, preserving the maximum amount of image information for post-processing. However, this format has largely been superseded by the newer CR2 and CR3 formats, which provide more advanced features and better compression. CRW files require specialized software for viewing and editing, and they are generally larger in size compared to standard compressed image formats.

PNG stands for Portable Network Graphics, and it is a popular raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF, and is the most used lossless image compression format on the Internet. It supports a range of colors, including full-color and grayscale images, and also supports transparency, making it suitable for graphics, logos, and detailed artwork.
