About PEF files

PEF (Pentax Electronic File) is a proprietary RAW image format developed by Pentax for its digital cameras. This format is based on the TIFF/EP standard and is designed to store uncompressed, unprocessed data from the camera's image sensor. PEF files are typically larger than other RAW formats, such as CR2, NEF, and DNG, and offer more flexibility in post-processing. They can be opened and edited with a variety of image editing programs, such as Adobe Photoshop, Lightroom, and GIMP.

Converting PEF files to other formats can be challenging due to the proprietary nature of the format. It is important to consider the quality of the converted file, as well as the compatibility of the output format with the desired software. Additionally, some programs may not support the conversion of PEF files, making it difficult to use them in other applications. Software such as IrfanView, GIMP, and Adobe Photoshop can be used to convert PEF files to more widely supported formats such as JPEG, TIFF, and PNG. However, these programs may not be the most user-friendly or efficient for this task. For those who need a more reliable and efficient way to convert PEF files, the Convert.Guru is a great option.

PEF files have some drawbacks, such as their large file size, which can make them difficult to share and store. Additionally, since the format is proprietary, it is not widely supported by other applications and programs. For these reasons, it is often best to convert PEF files to more widely used formats such as JPEG, TIFF, or PNG. Using the free and easy online website Convert.Guru is a great way to do this quickly and easily.

The PEF Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PEF converter.
