CRW to PNG Converter

Canon Raw CIFF Image (CRW) file is a RAW file type that is proprietary to older-model Canon digital cameras. (Newer Canon digital cameras use the CR2 format.) In terms of structure, CRW is similar to the TIFF file format. The benefit of a CRW is that it is an unprocessed image that contains all of the file’s information, as captured by the camera. To learn more about the technical details of CRW, the Massachusetts Institute of Technology (MIT) offers a thorough explanation.

How to open a CRW file?

Since CRW is a proprietary file format for Canon, the best program to use to work with a CRW file is Canon’s Digital Photo Professional. Other great programs to consider are Adobe Lightroom and Adobe Photoshop. If you want to try a Microsoft product, such as Microsoft Windows Live Photo Gallery, then be sure to install the Microsoft Raw Image Extension. 

As a RAW file format, CRW can convert to many different types of image files. You can use our free CRW to JPG or Image Converter tools to convert your CRW files. In addition, you can use Adobe DNG to convert CRW to DNG.

Alternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page. One interesting feature of PNG files is the ability to create transparency in the image, particularly a transparent background.
