How to convert JPG to AVIF
- Select Choose files, or drag your JPG files onto the box. You can also paste an image.
- Each file converts on your device. A progress bar shows the status and nothing is sent anywhere.
- Select Download for one file, or Download all (ZIP) when you convert several at once.
- Encoding is slower than other conversions, so a large image can take several seconds. Files are processed one at a time to keep your device responsive.
Why convert JPG to AVIF
Website speed depends on image weight, and AVIF is one of the best ways to cut it. A JPG photo often drops by a third to a half with no visible loss. Smaller images also save mobile data for your visitors.
About the formats
JPG is widely supported and easy to work with, but its files are larger than they need to be for the web. AVIF is a newer format based on the AV1 video codec. It keeps more detail per kilobyte than JPG, PNG and even WebP, and it supports transparency.
Use the quality slider to balance size and sharpness: 55 to 65 percent is a good start for photos. The speed menu trades time for smaller files. Most current browsers can display AVIF, but old programs, some social networks and many email clients still cannot, so keep a JPG as a fallback for those uses.
Tips
