PEF to CR2
File Converter

PEF stands for Pentax Electronic File, and it is a raw image file format used by Pentax digital cameras. This format stores unprocessed image data directly from the camera's sensor, allowing photographers to maintain a high level of control over image adjustments such as exposure, color balance, and sharpness during post-processing. PEF files provide the potential for higher image quality, as they preserve more information than standard compressed image formats.

CR2 is a raw image file format used by Canon digital cameras, capturing all the data from the camera’s sensor without compression or processing. This format offers photographers the ability to make extensive post-processing adjustments, providing greater control over image quality, exposure, and color balance. However, CR2 files are larger in size compared to compressed image formats and require specialized software to view and edit.
