The PST file (Outlook Personal Storage File) is a proprietary file format used by Microsoft Outlook to store copies of messages, calendar events, and other items within Microsoft software such as Microsoft Exchange Client, Windows Messaging, and Microsoft Outlook. The PST file acts as a local archive, allowing users to manage their email data offline, organize their email inbox, and back up important correspondence, contacts, and calendar appointments. It can be password protected for added security.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
