Why Convert JPG to AVIF?
JPG to AVIF conversion can reduce file sizes by up to 50% compared to JPG at equivalent quality, according to various benchmarks.

It delivers better quality at lower bitrates than JPG, making it ideal for modern web applications where performance matters.
JPG has been the standard for photos on the web for decades, but AVIF represents the next generation of image compression. Browser support for AVIF is growing (Chrome 85+, Firefox 93+, Safari 16+), and many CDNs now serve AVIF automatically to compatible clients.
