Frequently asked questions
What is an AVIF file?
AVIF is a newer image format, based on the AV1 video codec, that makes files smaller than JPG or WebP at similar quality. Websites use it to load faster.
Why can’t I open AVIF files?
Modern browsers display AVIF, but some photo viewers, editors, older operating systems and upload forms still don’t. Converting to JPG fixes that.
Will the JPG be larger?
Usually yes, because AVIF is more efficient. Choose “Smallest file” or set a size limit if you need small JPGs.
Are my images uploaded?
No. Conversion happens in your browser, on your device.
