What is a RAF file?

The RAF extension identifies a raw image file generated by Fujifilm digital cameras. It contains unprocessed data directly from the camera's image sensor-typically Fujifilm's proprietary X-Trans CMOS or standard Bayer filter arrays-along with a JPEG preview and Exif metadata. The file structure encapsulates the sensor's exact luminance values and color information before demosaicing or gamma correction is applied. This format allows for extensive post-processing flexibility regarding white balance, exposure, and color grading compared to compressed formats.

How to open a RAF file

To view or edit RAF files, users require software capable of interpreting the specific sensor data mapped in the file header. Fujifilm provides 'Fujifilm X RAW STUDIO' for native processing. Industry-standard applications such as Adobe Lightroom Classic, Capture One, and the open-source RawTherapee support RAF decoding. Microsoft Windows users may need to install the 'Raw Image Extension' package, while macOS Preview possesses built-in support for most RAF iterations via Apple's Core Image framework.

What is a WEBP file?

WebP is a raster graphics file format developed by Google specifically for web optimization, utilizing the Resource Interchange File Format (RIFF) container. It employs predictive coding based on the VP8 video codec for lossy compression and the LZ77 algorithm with entropy coding for lossless compression. WebP supports transparency (alpha channel) in both lossy and lossless modes, as well as animation, often achieving file sizes 26-34% smaller than comparable JPEG or PNG files while maintaining high structural similarity (SSIM) index scores.

How to open a WEBP file

WebP is natively supported by all modern web browsers, including Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. For offline viewing, Windows 10 and 11 support WebP via the Photos app (often requiring the Webp Image Extensions package), while macOS users can view them in Preview (macOS Big Sur and later). Legacy systems or incompatible editors require conversion tools or third-party viewers like IrfanView to render the image data.
