The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.
The JPEG XL (JXL) file extension, is a next-generation image format developed by the Joint Photographic Experts Group, combining Google's PIK and Cloudinary's FUIF formats. It supports both lossy and lossless compression, offering up to 60% better compression efficiency compared to traditional JPEG, while maintaining high image quality. Standardized in 2021, JPEG XL is designed for web delivery, professional photography, and digital printing, supporting ultra-high-resolution images, wide color gamuts, and advanced features like progressive decoding and multiple layers.
