免費線上 PPS 轉 OTB 轉換器

The file stores slides with presentations and slide shows filled with graphics, audio, video, and textual information. The format is identical to the PPT file, except for the editing feature, and is a bit smaller. Can be opened only in preview mode and prevents other users from changing the structure and content of the presentation.

This format was created by Nokia for use in its proprietary phones. A bitmap image was used to transfer image files between devices over a wireless connection. It was mainly used when exchanging multimedia text messages that support inserting pictures.
