Understanding ART and JXL File Formats

ART File Format

ART is a proprietary, highly compressed raster image format originally created by AOL to facilitate fast image downloads on slow internet connections. ART images often suffer from reduced color fidelity and visible artifacts due to the aggressive compression method. The format is now considered legacy with limited modern usage.

JXL (JPEG XL) File Format

JPEG XL (JXL) is a modern open-source image compression format offering both lossy and lossless compression. It supports high dynamic range (HDR), wide color gamut, transparency, and animation. JXL offers superior compression efficiency compared to older formats like JPEG and WebP, making it ideal for web use, archiving, and professional workflows.

Why Convert ART to JXL?

Reduce file sizes significantly while maintaining or improving image quality.
Upgrade from outdated ART images to a modern, supported format.
Support advanced features like transparency, HDR, and animation unavailable in ART.
Improve compatibility with modern browsers and imaging software.
Enhance web performance and user experience with faster loading images.

When Should You Convert ART Files to JXL?

When modernizing legacy web or fax images for current applications.
To optimize images for fast web delivery with excellent quality.
For long-term archiving with lossless compression.
When needing images that support progressive loading and transparency.
To ensure images are compatible with latest web technologies and software.
