Frequently Asked Questions
Is it worth converting to AVIF instead of WebP?
AVIF usually compresses even better than WebP, though encoding is somewhat slower; for key images on your site it can be worth it.
Do all browsers support AVIF?
The vast majority of modern browsers already support it, though it's wise to keep JPG as a fallback for very old browsers.
Does AVIF support transparency?
Yes, AVIF supports an alpha channel, though that doesn't apply here since JPG has no transparency to begin with.
