About JXL files
JXL (JPEG XL) is a next-generation image format designed to replace JPEG while maintaining backward compatibility. It offers significantly better compression efficiency, producing files up to 60% smaller than JPEG at the same quality level. JXL supports both lossy and lossless compression, HDR imaging, transparency, and progressive decoding. With its superior quality-to-size ratio and modern features, JXL is ideal for web images, photography, and digital archiving where quality and efficiency matter.
About QOI files
QOI (Quite OK Image) is a fast, lossless image format designed for simplicity and speed. It offers extremely fast encoding and decoding with minimal code complexity, making it ideal for real-time applications and embedded systems. QOI provides lossless compression comparable to PNG but with much faster processing. While file sizes are typically larger than compressed formats, QOI excels in scenarios where speed and simplicity are prioritized over file size.
