Imageconverter - 565 V2.3

The embedded world is moving toward higher-resolution, 24-bit displays (even on microcontrollers). However, the majority of low-power IoT, e-paper, and cost-sensitive devices still rely on 16-bit color. As of 2025 (and looking forward), imageconverter 565 v2.3 remains actively used in:

No major rewrite ("v3.0") has gained the same traction because v2.3 "just works." Its stability, low resource usage, and predictable output make it a classic. imageconverter 565 v2.3

Before understanding the tool, you must understand the format. RGB 565 is a 16-bit color encoding scheme: No major rewrite ("v3

By packing a pixel into exactly 16 bits (2 bytes), RGB 565 uses half the memory of full RGB 888 (24-bit) and significantly less processing power than 32-bit RGBA. This is ideal for microcontrollers with limited RAM and SPI or parallel displays with 16-bit interfaces. By packing a pixel into exactly 16 bits

ImageConverter 565 v2.3 automates the tedious process of:

Version 2.3 introduces enhanced handling of 32-bit RGBA source images.

One of the most common pitfalls in embedded graphics is byte order mismatch. Version 2.3 includes a "Swap Bytes" toggle to address displays that expect Big Endian input (common in older Solomon SSD and Ilitek ILI controllers) versus the native Little Endian of the MCU memory.
