What is AVIF?
AVIF stands for AV1 Image File Format. It stores images compressed using AV1 in a container based on HEIF. The format supports features such as transparency and high dynamic range.
Conversion requires your browser to decode the source AVIF. This tool produces an 8-bit sRGB still JXL image and does not preserve animation, HDR or original metadata.
What is JXL?
JXL is the file extension for JPEG XL, an image format designed for efficient image compression. JPEG XL supports lossy and lossless compression as well as transparency, making it suitable for both photographs and graphics.
This AVIF to JXL converter creates still, 8-bit sRGB images. Choose high quality to balance detail and file size, or lossless to preserve the decoded pixels. File-size savings are not guaranteed, and JPEG XL support varies between browsers and image applications. Keep your original AVIF files for compatibility.
