Convert MONO to OTB
Convert MONO images to OTB format, edit and optimize images online and free.
The MONO file extension stands for "Monochrome Bitmap" and is used for storing raw bi-level bitmap images, which are essentially black-and-white images without any color or grayscale. This format is primarily utilized in applications requiring simple, high-contrast images, such as fax transmissions and certain types of document scanning. The MONO format, characterized by its least-significant-byte first order, has been supported by various image processing tools. Its history traces back to early bitmap graphics needs, emphasizing simplicity and efficiency in image storage and processing.
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.
