Convert PSD to OTB

The PSD file extension stands for Photoshop Document, which is the native file format for Adobe Photoshop. It is primarily used to save graphics and images, preserving layers, masks, transparency, and other editing features, allowing for non-destructive editing. Introduced in 1988 with Photoshop's first release, PSD files have since become a standard in the graphic design and digital imaging industry due to their flexibility and support for various color modes and channels, including RGB, CMYK, and grayscale.

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.
