3FR to JXL
File Converter

3FR is a raw image file format used by Hasselblad digital cameras, capturing all the data as sensed by the camera's sensor without processing or compression. This format allows for extensive post-processing capabilities, offering photographers greater control over image adjustments such as exposure, color balance, and detail, but results in larger file sizes compared to standard compressed image formats.

JXL stands for JPEG XL, a next-generation image coding standard developed by the Joint Photographic Experts Group (JPEG). JPEG XL is designed to provide efficient compression for both lossless and lossy image storage, offering high image quality at lower file sizes compared to previous standards. It supports a wide range of features including high dynamic range, wide color gamut, and progressive decoding, making it suitable for use in various applications from web graphics to professional photography. Despite its advantages, as a newer standard, JPEG XL may not yet have widespread support across all platforms and software.
