Understanding FLIF and JXL File Formats

What is FLIF File Format

FLIF (Free Lossless Image Format) is a highly efficient lossless image compression formatdesigned to exceed PNG, lossless WebP, and JPEG 2000 in compression ratio. FLIF supportsprogressive interlacing for progressive display but is no longer actively developed.

What is JXL File Format

JXL (JPEG XL) is a modern image format designed as a next-generation replacement for JPEG, offering excellent lossy and lossless compression, HDR, wide color gamut, alpha transparency, and progressive decoding. JXL provides superior compression and quality for web, print, and archival purposes.

Why Convert FLIF to JXL?

Modern & Efficient Compression: JXL offers better performance for both lossy and lossless compression.
Wide Feature Support: Supports HDR, alpha transparency, and progressive decoding.
Broad Compatibility: Increasing adoption across browsers, image editors, and devices.
Lossless and Lossy Options: Flexible compression modes tailored to user needs.
Fast Loading & Small Size: Ideal for web use with faster decoding and smaller sizes.

When Should You Convert FLIF Files to JXL?

When optimizing images for web and digital delivery with better compression and features.
For converting lossless FLIF images to a widely supported modern image format.
To use images in HDR and wide color workflows with higher fidelity.
When needing progressive loading for better user experience online.
For archival and print where a single format supports multiple use cases.
