卸载 (xiè zǎi) is a verb meaning 'to uninstall' — specifically, to remove software or an application from a computer or mobile device. The character 卸 (xiè) means 'to unload' or 'to remove', often used in contexts like unloading cargo or taking off equipment; 载 (zǎi) means 'to carry' or 'to load'. Together, 卸载 literally conveys the idea of 'unloading what was loaded', making it a natural and logical term for removing installed software. It is widely used in digital settings, especially in operating systems, app stores, and technical support instructions.

This term is neutral in register and commonly appears in both written and spoken Chinese when discussing device maintenance, system updates, or troubleshooting. Unlike general-purpose verbs like 删除 (shān chú, 'to delete'), 卸载 emphasizes the complete removal of a program along with its associated files and registry entries — not just deleting a file or shortcut. It is most frequently paired with software names, app icons, or installation packages.
