可移植的可执行文档（英语：Portable Executable，缩写为PE）是一种用于可执行文档、目标文档和动态链接库的文档格式，主要使用在32位和64位的Windows操作系统上。“可移植的”是指该文档格式的通用性，可用于许多种不同的操作系统和体系结构中。PE文档格式封装了Windows操作系统加载可执行进程代码时所必需的一些信息。这些信息包括动态链接库、API导入和导出表、资源管理数据和线程局部存储数据。在Windows NT操作系统中，PE文档格式主要用于EXE文档、DLL文档、SYS（驱动进程）和其他文档类型。可扩展固件接口（EFI）技术规范书中说明PE格式是EFI环境中的标准可执行文档格式。开头为DOS头部。

The Portable Executable (PE) format is a file format for executables, object code, DLLs, FON Font files, and others used in 32-bit and 64-bit versions of Windows operating systems. The PE format is a data structure that encapsulates the information necessary for the Windows OS loader to manage the wrapped executable code. This includes dynamic library references for linking, API export and import tables, resource management data and thread-local storage (TLS) data. On NT operating systems, the PE format is used for EXE, DLL, SYS (device driver), and other file types. The Extensible Firmware Interface (EFI) specification states that PE is the standard executable format in EFI environments.
