Frequently asked questions
Does converting WebP to AVIF lose quality?
AVIF is a compressed format. At the default quality setting the difference is invisible to the eye; move the Quality slider up for maximum quality or down for smaller files.
Is transparency kept?
Yes. Transparent areas in your WebP stay transparent in the AVIF.
Are my images uploaded to a server?
No. Conversion happens entirely in your browser, so your images never leave your device. It also works offline once the page has loaded.
Can I convert many images at once?
Yes. Drop as many images as you like – they are converted in parallel. Download them one by one or all together as a ZIP file.
