APNG to JXL converter
Animated PNG (APNG) to JXL free online converter
Convert animated PNG (APNG) files to JPEG XL (JXL) format. JPEG XL is a next-generation image format designed to eventually replace both JPEG and PNG, offering excellent compression efficiency for both lossy and lossless content. For animated images, JXL can achieve significantly smaller file sizes than APNG while maintaining comparable quality.
Note on browser support: As of 2025, animated JXL is not yet supported by any major web browser (Safari supports still JXL only). The converted files will not display inline on this page, but can be downloaded and used in applications that support the format, or kept for future use as browser support expands.
If you experience any issues with the conversion, you can try to upload your file to JXL maker instead. It will give you some options for finer control, e.g. manually setting frame disposal method, loop count and delay times.
