localutilitybox 1.1.1

A versatile utility for local image and document processing

localutilitybox

Don't waste your time searching for web solutions - do it in your terminal.

localutilitybox is a privacy-first suite of file-processing utilities that runs entirely on your machine. No uploads, no third-party servers, no subscriptions. Use it from the command line or through the modern desktop GUI.

Features

• Image Processing - convert between WebP, JPG, PNG, TIFF and HEIC; resize and compress; remove backgrounds; convert to greyscale; split long PNGs into multi-page PDFs; extract EXIF metadata; OCR text from images; generate QR codes.
• PDF Management - merge, split, compress, rotate/reorder and watermark PDFs; convert pages to PNG/JPG.
• Document Conversion - DOC/DOCX to PDF and back.
• Data Format Conversion - CSV, Excel and JSON, any direction.
• Video / Audio - extract audio tracks from video files (MP3, WAV, AAC, OGG, FLAC, M4A); convert video clips to animated GIFs.
• Desktop GUI - a modern sidebar-based interface with dark/light theme support, drag-and-drop file input, and output directory selection, built with customtkinter.
• CLI - every tool is also available as a standalone terminal command. Run localutilitybox (or lub) to list them all.

Installation

pipx (recommended)

pipx installs Python CLI apps in isolated environments while making the commands available globally.

# macOS
brew install pipx

# Windows (PowerShell or Command Prompt)
# Option 1: pip
py -m pip install --user pipx
py -m pipx ensurepath
# Option 2: Scoop (if installed)
scoop install pipx

# Ubuntu / Debian
sudo apt install pipx

# Fedora
sudo dnf install pipx

# Arch Linux
sudo pacman -S python-pipx

# Other Linux: install via pip
python3 -m pip install --user pipx

# Then (all platforms)
pipx ensurepath
# Restart your terminal (or source ~/.bashrc / ~/.zshrc on Linux/macOS)

# From PyPI (after first release)
pipx install localutilitybox

# Or from source
pipx install git+https://github.com/elokwentnie/localutilitybox.git

Optional extras

# Drag-and-drop in the GUI (Linux, macOS, Windows)
pipx inject localutilitybox tkinterdnd2

# AI background removal (large download)
pipx inject localutilitybox 'rembg[cpu]'

From source

git clone https://github.com/elokwentnie/localutilitybox.git
cd localutilitybox

# Create and activate virtual environment
python -m venv .venv
# Windows:  .venv\Scripts\activate
# Linux/macOS:  source .venv/bin/activate

pip install .

# Optional extras:
pip install tkinterdnd2     # drag-and-drop in the GUI
pip install 'rembg[cpu]'   # AI background removal

Verify

lub                     # list all available tools
heic_to_jpg --help      # test a CLI command
lub-gui                 # launch the GUI

GUI prerequisites

The GUI depends on tkinter (required by customtkinter). Install it if your Python distribution does not bundle it:

# macOS (Homebrew)
brew install python-tk@3.13

# Linux: see "System dependencies" table above (python3-tk / python3-tkinter / tk)

# Windows: tkinter is included with Python from python.org

On Linux, the GUI runs on X11 or Wayland with a desktop environment. On Windows, use the standard desktop. For drag-and-drop file input on any platform, install the optional tkinterdnd2 extra:

pipx inject localutilitybox tkinterdnd2

Usage

Desktop GUI

localutilitybox-gui   # or: lub-gui

The GUI provides a sidebar with every tool organised by category. Select a tool, fill in the inputs, and click the action button. A status bar shows real-time progress and the output file location. Switch between System, Light and Dark themes from the bottom of the sidebar. Drag-and-drop file input is supported when tkinterdnd2 is installed (see GUI prerequisites above).

Command Line

Every tool ships as its own command. Run localutilitybox (or lub) to see the full list. A few examples:

# Image conversion
webp_to_jpg image.webp -o image.jpg -b white
heic_to_jpg -f photo1.heic photo2.heic
heic_to_jpg -d /path/to/heic/files
