About Pico Image Tool
PicoImageTool is a lightweight, portable application designed for preparing graphics for retro computers, embedded systems, and other hardware with limited display capabilities.
The application provides tools for image resizing, color quantization, palette management, and dithering, allowing modern images to be converted into formats suitable for low-color and indexed graphics systems.
PicoImageTool was originally developed in late 2025 as a small internal utility for Raspberry Pi Pico (hence the name) projects using VGA output.
The initial purpose was to convert PNG images into raw indexed graphics data while maintaining a separate, unified palette.
What began as a simple hand written project-specific tool has since evolved into a more versatile image conversion utility, with an improved interface, additional processing algorithms, and support for retro image formats. Currently its mostly vibe coded using Codex.
It's completely free and requires no installation.
Requirements: .NET 10 Desktop Runtime x64
