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 Portable Network Graphics (PNG) file extension, established in 1996, serves as a widely-used raster graphics format that supports lossless data compression. Initially developed as a superior, patent-free replacement for the GIF format, PNG is prevalent in the IT industry for web design, digital photography, and complex graphics due to its capability to handle detailed images with transparent backgrounds and its extensive color range. Known for maintaining high-quality visuals without increasing file size significantly, PNG remains an indispensable tool in professional digital imaging and web development.
