Why AVIF needs converting
AVIF is the most efficient common image format, but support is still patchy. Many desktop editors, older phones and office printers cannot open it, so converting to WebP makes the picture usable everywhere.
What happens when you convert
Your browser decodes the AVIF file to raw pixels, then re-encodes them as WebP locally on your device. Decoding is exact, so the WebP keeps everything the AVIF contained.
AVIF is efficient but not universal. Older browsers, many desktop apps and some printers cannot open AVIF, while WebP works almost everywhere.
Will I lose quality?
Converting decodes the AVIF to exact pixels first, then re-encodes to WebP. Nothing is lost in the decode step.
What if my browser cannot open the AVIF?
This tool needs your browser to decode AVIF first. Use a recent Chrome, Edge or Firefox. If the file will not load, the browser simply does not support AVIF decoding.
Are AVIF files really that much smaller?
Yes. AVIF is often 50 percent smaller than JPG at similar quality, which is why converting back to WebP usually produces a bigger file.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device.
