How do I convert HEIC to JXL using LetsConvert?

Upload your HEIC file, choose JXL as the output format, optionally adjust quality or resolution, and click 'Convert'. Download the resulting JXL file—all done in your browser with no software install. You can also batch-convert multiple HEIC files at once.

Why convert HEIC to JXL instead of keeping HEIC?

HEIC is Apple's default, often problematic on Windows or Android. JXL (JPEG XL) is a royalty-free, open standard with superior compression, transparency, HDR, and wide browser support. Converting reduces file size while preserving quality and improves compatibility across all devices and web platforms.

Does converting HEIC to JXL preserve metadata, transparency, and HDR?

Yes, our converter preserves EXIF/XMP metadata, ICC color profiles, transparency (alpha channel), and HDR information. However, any auxiliary data like depth maps or multi-frame bursts in HEIC are not supported by JXL and will be discarded. The main image is converted losslessly or with lossy settings you choose.
