Description
The CRW file format is a type of raw image file created by Canon digital cameras. It stands for Canon Raw CIFF (Camera Image File Format), which is a proprietary file format developed by Canon for capturing all the image data recorded by the camera's sensor when a photo is taken. Unlike JPEG or other compressed image formats, CRW files contain uncompressed and unprocessed data, offering photographers a higher degree of control over image adjustments such as exposure, white balance, and color corrections during the post-processing.
Based on HEVC (High-Efficiency Video Coding), the HEIF format is an image file container with one or multiple images and is the default image format for Apple Live Photos. It replaced the JPEG format as it's smaller in size and has lossless compression ensuring high-quality photos.
