About this converter

This free JPG to AVIF converter turns a JPG into AVIF — a next-generation format that is often much smaller than JPG at the same quality, perfect for fast-loading pages.

Everything runs in your browser — your image is never uploaded to a server.

Good to know

  • The AVIF encoder downloads once (a small WebAssembly module), so a connection is needed the first time
  • AVIF encoding is thorough, so larger images can take a few seconds

How to use it

  • Upload your JPG — click the upload area or drag and drop a .jpg file
  • Choose the quality — higher keeps more detail; lower makes a smaller file
  • Download — save your AVIF
