Tilf — Pixel Art Editor
Tilf (Tiny Elf) is a simple yet powerful pixel art editor built with PySide6. It’s designed for creating sprites, icons, and small 2D assets with essential tools, live preview, undo/redo, and export options.
There are several Pixel Art Editors that do the same things and even much more, but many require an account registration or the insertion of an e-mail or have a certain business model.
I'm not interested in all that, my goal is to be able to create sprites freely, with (almost) zero dependencies, zero setup time, zero installations:
Tilf starts and I begin to draw what I want.
It runs on Windows, MacOS and GNU/Linux.

I’m aware that the code quality isn’t great. I didn’t prioritize it when writing this. This project was something I put together during my spare time, and a lot of it could be written much better. There's definitely room for improvement, so I'm more than happy to accept PRs from anyone willing to contribute.
Why doesn't this tool have many commits?
Because I mainly used it for learning and personal purposes. Publish it as an Open Source project might be interesting for others as well.
Table of Contents
Features
Drawing tools: Pencil Eraser Fill (bucket) Eyedropper Rectangle (stroke) Ellipse (stroke)
Canvas: New image with custom dimensions Zoom 1–50x (mouse wheel or slider) Editable background color (alpha supported) Optional grid with customizable color Clear canvas
Workflow: Undo/Redo with history up to 50 states Drag & drop images to open Real-time preview in a side dock (you can move it wherever you want)
Import/Export: Open PNG, JPEG/JPG, BMP Export to PNG (with or without transparency), JPEG/JPG, BMP
Handy details: Hold Shift while drawing rectangles/ellipses to constrain to squares/circles Grid is shown when zoom (cell size) is at least 4
Requirements
Python 3, virtualenv
OS: Windows, MacOS or GNULinux
Dependencies: PySide6 PyInstaller
I did not use uv or poetry for this project; I don't think it is necessary to introduce a tool of that kind for a project that is, all things considered, simple.
Build on MacOS and GNU/Linux
Clone the repository:
git clone https://github.com/danterolle/tilf.git && cd tilf
This project has a Makefile that automates all the necessary build and cleanup operations for Tilf (for MacOS and GNU/Linux only), so we just need to run:
make
The executable will be in the dist folder.
./tilf
Enjoy!
About Windows
Run from source
Clone the repository by using Git Bash:
git clone https://github.com/danterolle/tilf.git
cd tilf
Create a virtual environment:
py.exe -m venv env
Activate the virtual environment:
./env/Scripts/activate
Install the dependencies:
pip install pyside6 pyinstaller pillow
Note:
And finally, run the application:
py.exe ./main.py
Build executable .exe
Clone the repository by using Git Bash:
git clone https://github.com/danterolle/tilf.git
cd tilf
./env/Scripts/activate
Install the dependencies:
pip install pyside6 pyinstaller pillow
Run PyInstaller:
pyinstaller --name tilf --onefile --windowed --icon assets/icon.icns --add-data assets:assets --add-data style.qss:. main.py
The executable will be in the dist folder.
./tilf
Keyboard Shortcuts for file operations
File: New: Ctrl+N Open: Ctrl+O Save: Ctrl+S
Edit: Undo: Ctrl+Z Redo: Ctrl+Y
Tools: Pencil: B Eraser: E Bucket: G Eyedropper: I Rectangle: R Ellipse: C
Shapes: Constrain to square/circle: hold Shift
Save and Auto-Save
Export formats: PNG: optionally keep transparency. JPEG/JPG, BMP: no transparency.
On close, if there are unsaved changes, a recovery .png is automatically saved into a tilf_autosaves folder next to the startup script, with a timestamped filename.
Tips and Known Limits
Undo/Redo history is capped at 50 states to limit memory usage.
Large flood fills may take longer on big images.
The grid appears when zoom (cell size) is at least 4.
Very large images may impact performance; Remember: Tilf targets compact pixel art and sprites.
Troubleshooting - Work In Progress
ModuleNotFoundError: No module named 'PySide6'
Ensure your virtualenv is active and run: pip install pyside6
