WPS Office is an all-in-one office suite that integrates Word, PDF, Excel, PowerPoint, and other tools into one powerful toolkit. It is developed by the Chinese software developer Kingsoft and is available for Microsoft Windows, macOS, Linux, iOS, Android, and HarmonyOS. WPS Office is made up of three primary components: WPS Writer, WPS Presentation, and WPS Spreadsheet. It also includes WPS PDF and WPS AI. WPS Office is a strong alternative to Microsoft Office, boasting basic and advanced functions, but with one distinct advantage—its completely free. It is highly compatible with MS Office Word, Excel, and PPT. WPS Office allows file sharing, editing, and merging multiple files, whether online or offline. It is also lightweight and requires less memory, making it faster than most office software. WPS Office supports multiple operating systems such as Windows, macOS, Linux, Android, iOS, and HarmonyOS.
