A simple and easy-to-use textures packer and font atlas generator.

What can I do with rTexPacker?

rTexPacker is a powerful tool to package sprites or fonts into an atlas, to improve drawing performance on games.

Handmade Software

rTexPacker is handmade software, it has been meticulously developed using the C programming language, with great attention put on every line of code written. This approach usually results in highly optimized and efficient code, but it is also more time-consuming and require a higher level of technical skills. The result is great performance and small memory footprint.
