What Is JPG to AVIF Conversion?

JPG is a widely supported compressed image format commonly used for photos, websites, cameras, and social media. JPG uses lossy compression and is widely supported by browsers and editing applications.

AVIF is a modern AV1-based image format designed for high compression efficiency, strong visual quality, smaller files, and modern web delivery. Converting JPG to AVIF can reduce file size, although support in older software may be limited.

Need to reduce file size without changing format? Use the Image Compressor. Need exact pixel dimensions instead? Try our Image Resizer.
