How do I convert an AVIF file to JXL?

Upload your .avif file, select JXL as the output format, and choose if you want lossless or high-quality compression. Click 'Convert' to process the file. Once done, download your .jxl file. Our tool works directly in the browser without extra software.

Why should I convert AVIF to JXL?

JPEG XL generally provides better compression than AVIF, resulting in smaller file sizes at similar quality. It also supports lossless encoding, alpha transparency, and high dynamic range, making it a future-proof format for professional and web use. Additionally, some software and browsers have limited AVIF support, so converting to JXL can improve compatibility in broader workflows.

What happens to transparency, color profiles, and metadata when converting?

In lossless conversion, the alpha channel, embedded ICC color profiles, and EXIF/XMP metadata are preserved exactly. Both AVIF and JXL are raster formats, so vector shapes or layers are flattened into pixels. Resolution and DPI remain unchanged, and for HDR content, we preserve the wide color gamut and transfer function.
