If you need to explore modern alternatives or scale your asset workflows, let me know: RGB565 to C/C++ Converter - Marlin Firmware imageconverter 565 v2.3
The final output is a that represents the entire image in a format the display's driver can interpret directly. This process is highly efficient, enabling conversion speeds of up to 1,000+ pixels per second .

In the world of embedded systems, IoT devices, and DIY electronics, bringing graphical interfaces to life is a common challenge. Unlike desktop computers or smartphones, microcontrollers like Arduino, STM32, or ESP32 have limited resources. Displaying images requires converting standard image formats (JPG, PNG) into a raw format that microcontrollers can process quickly.
Before diving into the software, it is vital to understand why standard images (.png or .jpg) cannot be directly uploaded to a microcontroller. Can’t copy the link right now
Click . The software generates a text file containing an array of hexadecimal values. A 10x10 pixel image will yield an array of exactly 100 hex tokens, looking similar to this:
Compared to a standard 24-bit RGB888 image (which uses 3 bytes per pixel), an RGB565 image . This is a critical advantage for microcontrollers (MCUs) with very limited onboard RAM, where every byte counts.
(specifically version 2.3 ) is a legacy utility tool developed by Henning Karlsen as part of his UTFT library tools. It is primarily used to convert standard image files (like .jpg or .png) into RGB565 raw pixel data or C-formatted arrays for use with Arduino or other microcontrollers driving TFT displays.
