icoextract

Build Status

icoextract is an icon extractor for Windows PE files (.exe/.dll/.mun), written in Python. It also includes a thumbnailer script (exe-thumbnailer) for Linux desktops.

This project is inspired by extract-icon-py, icoutils, and others.

icoextract aims to be:

  • Lightweight
  • Portable (cross-platform)
  • Fast on large files

Installation

Installing from source

You can install the project via pip: pip3 install icoextract[thumbnailer]

On Linux, you can activate the thumbnailer by copying exe-thumbnailer.thumbnailer into the thumbnailers directory:

  • /usr/local/share/thumbnailers/ if you installed icoextract globally
  • ~/.local/share/thumbnailers if you installed icoextract for your user only

The thumbnailer should work with any file manager that implements the Freedesktop Thumbnails Standard: this includes Nautilus, Caja, Nemo, Thunar (when Tumbler is installed), and PCManFM. KDE / Dolphin uses a different architecture and is not supported here.

Distribution packages

You can install icoextract from any of these distribution repositories:

Packaging status

Usage

icoextract ships icoextract and icolist scripts to extract and list icon resources inside a file.

Note: recent versions of Windows (Windows 10 1903+) have moved icons from system libraries (shell32.dll, etc.) into a new C:\Windows\SystemResources folder. icoextract can extract these .mun files natively, but the .dlls themselves no longer contain icons.
