Part 2: What are CR2, CRW, and HEIF Files?

1. Canon RAW CR2/CRW

CR2 and CRW are the RAW formats for Canon digital images. It is TIFF-based and able to preserve more details from your camera’s sensor than JPG. The CR2/CRW files record the original white balance, exposure, and detail among other photo components.

Since Canon’s RAW files contain so much unprocessed data, they are pretty large. On the other hand, it means that RAW files offer much higher quality than compressed images.


The biggest benefit of the Canon RAW file is the excellent quality. It makes sense that it contains all of the image information from the sensor. That leaves more space to create the end photographic result that you desire. It allows you to adjust your image color and appearance easily.


The downside of CR2/CRW files is the file size. Thus, your photos take up a great deal of space. Plus, you have the Canon RAW viewer to view and browse both CR2 and CRW files on your computer with ease.


2. Canon RAW HEIF

Why does Canon use the new HEIF format? It is first introduced with the EOS-1D X Mark III in 2020 and also is available in the EOS R5 and EOS R6. It is not only a successor of photos but also contains data for several different types of media.

How about the quality of Canon’s new RAW file format? Compared to the 8-bit JPEG, HEIC contains 4 times more color and tonal information. Besides, the HEIC/HEIF files provide more post-processing and editing flexibility. But HEIF compression is 50% more effective than JPEG, which means you can get better quality with a smaller size.


Provide better compression algorithms with better quality and small size.

Less JPEG artifacts, image noise and color banding, and related problems.

Contain more information, which is better than Canon CR2/CRW/JPEG.


The new Canon RAW HEIF is not compatible with most photo editors.

Difficult to distinguish the quality and others for beginners or amateurs.
