What is JPG?
JPG (or JPEG) is a widely used image format known for its efficient lossy compression, which reduces file size while maintaining decent image quality. It’s ideal for photographs and realistic images with many colors and gradients. JPG files are supported across all devices, browsers, and software, making them highly compatible. However, repeated saving can degrade image quality due to compression. It doesn't support transparency or animation.
What is JXL?
JXL (JPEG XL) is a modern image format designed to replace older formats like JPEG, PNG, and even GIF. It offers excellent compression efficiency while preserving high image quality, making it ideal for both photos and web graphics. JXL supports features like lossless and lossy compression, progressive rendering, wide color gamut, animation, and alpha transparency. One of its key advantages is significantly smaller file sizes compared to JPEG and PNG, without visible quality loss. While JXL is not yet supported across all browsers and platforms, it’s quickly gaining traction as a future-ready, open standard for image storage and delivery.
