Convert XBM to AVIF

The XBM (X11 Bitmap Graphic) file extension is a plain-text binary file format historically used in the X Window System to store monochrome bitmap images. Its primary use is for defining small, simple graphics such as icons and cursors. Originating from the 1980s, XBM files enable the inclusion of image data directly in C source code, facilitating easy integration and compilation within applications. While their use has declined with the advent of more advanced graphics formats, XBMs remain relevant for legacy systems and specific low-resource environments.

AVIF, or AV1 Image File Format, is a modern image format derived from the AV1 video codec developed by the Alliance for Open Media. It is designed to deliver high-quality images with superior compression efficiency compared to traditional formats like JPEG and PNG. This format supports advanced features such as HDR (High Dynamic Range), WCG (Wide Color Gamut), 10-bit color depth, and alpha transparency, making it ideal for web developers and digital content creators seeking to optimize performance and visual fidelity. Introduced in 2018, AVIF has rapidly gained adoption due to its open-source nature and effectiveness in reducing file sizes without compromising quality.
