OST

Outlook Offline Storage File

An OST (Outlook Offline Data File) is a file format used by Microsoft Outlook to store a synchronized copy of mailbox data locally, enabling offline access to emails, calendars, contacts, and other items. It is primarily used by Microsoft Outlook and can be accessed or converted using tools like Kernel OST to PST Converter, Stellar Converter for OST, and SysTools OST Viewer. The OST file structure is based on the Messaging Application Programming Interface (MAPI) and supports advanced features like synchronization with Exchange Server, encryption, and data compression for efficient storage and security.

JPEG

JPEG Image

JPEG is a widely used lossy compression format for digital images, balancing file size reduction with acceptable image quality. It is supported by most image editing software like Adobe Photoshop, GIMP, and web browsers, making it ideal for web use and digital photography. The format uses discrete cosine transform (DCT) for compression, supports progressive loading, and allows adjustable compression levels, though it sacrifices some detail due to its lossy nature.
