Convert RAF to APNG (Animated PNG)

The RAF file extension stands for Fujifilm Raw Image File, a format used by Fujifilm digital cameras to store uncompressed image data directly from the camera's sensor. Introduced to preserve maximum image quality, RAF files contain minimally processed data, allowing for extensive post-processing flexibility. This format, based on the TIFF/EP standard, includes metadata such as camera settings and format version. RAF files are primarily utilized by professional photographers and enthusiasts for high-quality image editing and archiving.

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.
