Download LCD Image Converter – Image to C Array Tool for Embedded LCD Displays

LCD Image Converter is a free, open-source tool for embedded systems developers that converts bitmap images and fonts into C source code arrays ready to be compiled into microcontroller firmware. It is designed for programmers working with monochrome or color LCD displays on Arduino, STM32, AVR, PIC, and other embedded platforms.

The tool allows you to import standard image files (BMP, PNG, JPG) and configure how they are converted — including bit depth, color format, pixel ordering, data orientation, and compression. The output is a ready-to-use C header file containing the image data as a byte or word array that you can include directly in your embedded project.

LCD Image Converter also supports font generation, allowing you to select system fonts or custom TTF fonts and convert character sets into the compact bitmap format required by embedded display drivers. It is widely used in the maker and embedded engineering communities for creating custom graphics and text for small displays.

Key Features

• Converts BMP, PNG, and JPG images to C arrays for use in embedded firmware.
• Configurable output: bit depth, color format (RGB565, monochrome, etc.), and byte ordering.
• Font generation from system or custom TTF fonts with character range selection.
• Preview panel showing how the image will appear on the target LCD display.
• Supports horizontal and vertical data scanning modes for different display controllers.
• Outputs C source and header files ready for direct inclusion in embedded projects.
• Open source under the GNU GPL license — free for personal and commercial use.
