Convert PWP to OTB

The PWP file extension stands for PhotoWorks Image File, associated with the PhotoWorks software developed by Seattle FilmWorks. Primarily used in the late 1990s and early 2000s for storing color images, PWP files are similar to SFW files and were commonly used for image downloads from the internet. Although the software is now discontinued, PWP files can be converted to standard JPG images using specific converters.

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.
