JXL to AVIF Converter
Processing entirely on your device — large files may take a moment.
JPEG XL is a next-generation format designed to succeed JPEG: it can recompress existing JPG files about 60% smaller with no additional quality loss, and supports lossless mode and animation. AVIF delivers the smallest files at top visual quality for modern websites — it is supported by all current browsers.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

Frequently asked questions
Is this JXL to AVIF converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will converting JXL to AVIF reduce quality?
AVIF uses lossy compression, so a small amount of recompression is unavoidable. The quality slider lets you choose between maximum fidelity and smallest file size — the default is visually indistinguishable for photos.
