Why convert JPG to AVIF?
AVIF is the most modern web image format — tiny files at high quality. Browser support is good but desktop software is still catching up.
What happens when you click convert
- The page reads your file using a JavaScript or WebAssembly decoder.
- It re-encodes the pixel data as a AVIF file.
- One file in, one file back. Several files in, a ZIP back.
Nothing leaves your browser
The whole conversion happens inside this tab. The simplest proof: load the page, kill your internet, run a conversion. Most converters still work.
