AVIF or WebP for your pictures?
Pick AVIF when the pictures go on a website you look after. Pick WebP when you want one file that works everywhere with no extra setup.
Both give you a much lighter file than a PNG and both keep a transparent background, so the choice is not really about the picture. It is about where it is going. AVIF is the lighter of the two, which is why it suits a site where you control how images are served and can offer something else to anyone whose browser is behind.
WebP is the easier one to live with. It has been around longer, it is understood by more software outside the web, and it takes less time to produce when you are converting a lot at once. If you are not sure, WebP is the safer default, and converting to WebP instead takes the same two clicks.
What to expect while it works
Converting a PNG to AVIF takes a little longer than the other formats on this site. That is normal, and it is the reason the file comes out as light as it does.
For one picture it is a short pause. For a folder of a few hundred it is worth starting when you have a moment free rather than waiting on it. Everything happens on your own computer, so the page stays usable while it works and nothing sits in a queue waiting for a server somewhere.
And it is a one-off cost. Once the picture is converted, every visitor who loads it gets the lighter file, every time. That is the whole point of the trade.
Questions people ask
AVIF if the pictures go on a website you look after and you can offer a backup file for older visitors. WebP if you want one file that works everywhere without any extra setup, or if you are converting a very large batch and would rather not wait.
Yes. A logo or icon with a see-through background stays see-through, with nothing to set beforehand. That puts AVIF alongside PNG and WebP, and apart from JPG, which cannot hold transparency at all.
AVIF takes more work to produce, which is the trade for how light the result is. You only pay that once, when you convert. Everyone who later loads the picture on your page gets the lighter file.
Not quite yet, and this is the real thing to weigh up. Every current browser shows AVIF, so websites are fine. Away from the web, support in desktop programs, office software and email is thinner, so AVIF is best treated as something you publish rather than something you archive.
Yes. Keep the PNG as your working copy and treat the AVIF as the version you publish. That way you always have something to go back to, and something to hand over if a client or a printer asks for a file.
Yes. Drop in as many as you like and they queue up together, then come back as one zip. Worth starting a big batch when you have a moment, since AVIF is the slower of the modern formats to produce.
