JPG to AVIF
AVIF produces much smaller files at comparable quality, which helps speed up a website and save bandwidth. The tool converts JPG to AVIF in your browser and falls back to the server if the browser cannot encode AVIF.
The image is converted in your browser — the file is not uploaded.

More about JPG to AVIF
Why convert JPG to AVIF
AVIF is a modern format based on the AV1 codec. It offers efficient compression and often produces smaller files than WebP at comparable quality. For a website that means faster loading and less bandwidth usage.
How it works
The browser decodes the JPG, draws it on a canvas and tries to save it as AVIF. If the browser does not support AVIF encoding, server-side processing with sharp takes over. In that case the file is deleted after download or within an hour.
What to know
AVIF is not supported by every older device and application. For a website, serve AVIF to modern browsers and JPG or WebP to the rest. Keep the original JPG for archiving and printing.
Questions and answers
Do all browsers support AVIF?
Current versions of Chrome, Firefox, Edge and Safari support AVIF. For very old clients, keep JPG or WebP as a fallback.
Why does the conversion sometimes run on the server?
Not every browser can encode AVIF through Canvas. If the browser fails, the file is processed on the server with sharp and deleted automatically.
How much smaller is the file?
AVIF is usually 30–50% smaller than JPG at similar visual quality. The exact result depends on the image and compression settings.
Is transparency preserved?
JPG does not support transparency, so the AVIF will not have it either. Use PNG to AVIF for transparent images.
