Convert pps to otb

What is the difference between .pps and .otb?

Description: A PPS file is a slide show created by Microsoft PowerPoint, a popular program included with Microsoft Office for creating presentations. It is saved as a completed slide show, which can be viewed by PowerPoint, OpenOffice, and several other presentation programs. PPS files are not editable like .PPT files.; The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.
