Version 2.3 introduces enhanced handling of 32-bit RGBA source images.
This format is the industry standard for small color displays because it reduces the memory footprint of an image by 33% compared to standard 24-bit RGB, while still maintaining high visual fidelity for human eyes, which are more sensitive to green light (hence the extra bit for green). Key Features of v2.3 imageconverter 565 v2.3
Provides better accuracy than generic online converters, minimizing color bleeding. Why You Need This Tool for Arduino/TFT Projects Version 2
Byte order mismatch. The display expects one order, but the tool output another. Fix: Re-export with the "Swap Bytes" option toggled opposite of your current setting. Alternatively, post-process the array with a small loop swapping (byte0, byte1) . Why You Need This Tool for Arduino/TFT Projects
Here is how to take an image from your computer and show it on a TFT using the UTFT library:
