## What it is
libPeConv is a C++ library for loading, manipulating, and dumping Windows PE (Portable Executable) files. It provides a 'swiss army knife' of helper functions for building custom PE loaders, including section remapping, relocations, import loading, IAT hooking, and memory PE dumping.

## Use cases
- manually map and execute a PE file in my own loader
- dump a PE from memory and rebuild its import table
- hook the import address table of a loaded PE
- build a PE binder that embeds and runs an executable from a resource
- parse and modify PE file sections and relocations
- write a custom PE loader for malware analysis

## When to choose
- you need fine-grained control over PE loading steps like relocations, imports, or IAT resolution
- you are doing malware analysis or reverse engineering on Windows binaries
- you want to dump and rebuild PEs from process memory
- you need to load PEs from memory buffers rather than disk

## When to avoid
- you need inline function hooking - use MS Detours or MinHook instead
- your application relies on MUI resources, which are unsupported
- you need a cross-platform PE parser that runs on non-Windows systems

## Facets
- artifact type: library
- maturity: active
- function: parser, security, reverse-engineering, developer-tools
- domain: security, reverse-engineering, windows, developer-tools
- platform: windows, cpp
- tags: pe-files, pe-loader, manual-mapping, iat-hooking, malware-analysis, pe-dumping
