Convert JPG files to AVIF in seconds. AVIF can be far smaller than JPG at similar quality, so pages load faster.
Drop one or more JPG files onto the page, or choose them from your device.
JPG has no transparency, so the picture stays solid. AVIF makes a smaller file by discarding a little detail. The quality slider lets you choose between a small file and the best look; 90 is a good start.
Press Convert, then download each AVIF file, or all of them as a ZIP.
JPG (JPEG image). JPG (also written JPEG) is the most common photo format. It squeezes pictures into small files by discarding detail the eye barely notices, and every phone, computer, website and printer can open it. It is best for photos and any picture you need to share or upload anywhere.
AVIF (AVIF image). AVIF is a newer format based on the AV1 video codec. It gives very small files with good quality and supports transparency, but older software and some phones cannot open it yet. It is best for websites that want the smallest possible pictures.
Add your JPG file, check that the target is AVIF, and press Convert. Then download the AVIF file. It takes a few seconds.
