AVIF is built on the AV1 video codec and typically stores a photograph in far fewer bytes than JPEG at a similar visual quality. For a website, that means faster pages and lower bandwidth for the same pictures. Every current major browser can display AVIF, so it is a practical format for web images today.
AVIF's quality scale is not the same as JPEG's: a lower number goes further, so this page starts at a moderate setting rather than a high one. Check the result in the editor and adjust if fine textures such as skin, fabric or foliage look too smooth, which is the usual sign that the setting is too low.
Support outside browsers is patchier. Older image editors, some email clients and many upload forms still reject AVIF, so keep the original JPEG if the picture has to travel beyond a web page. Encoding AVIF is also slower than other formats; a large photo can take a few seconds. Files are uploaded over an encrypted connection, converted on our own servers and deleted within one hour, and AVIF output is free on every plan.
Choosing a quality for AVIF
This page starts at 55, which on most photographs gives a file around half the size of a good JPEG with no difference at normal viewing size. For large banner images, where the eye has time to wander, 60 to 65 is a comfortable setting. For thumbnails and listing images, 45 to 50 still looks clean because the picture is small on screen. If you would rather not pick a number, switch to Smart mode: it tries settings between 45 and 70 and keeps the lowest one that still matches the JPEG you uploaded.
Judge the result on the things AVIF finds hardest: film grain, hair, grass, the weave of a fabric. If those look right, everything else does.
Serving AVIF with a fallback
On your own site, the HTML picture element lets you offer the same image in several formats. List the AVIF first, a WebP second and the original JPG as the plain image, and each browser takes the first one it can read. Visitors with an old browser still get a picture, and everyone else gets the smallest file. If your images go through a content delivery network, check its settings before converting anything by hand. Many of them can produce AVIF automatically for browsers that ask for it.
Two habits to adjust
A progressive JPEG appears blurry at first and sharpens as it arrives. An AVIF generally shows nothing until the whole file is there. The file is so much smaller that it usually wins anyway, but for a very large banner on a slow connection it is a reason to keep the dimensions sensible.
The other habit concerns the right-click. A visitor who saves an AVIF from your page gets a file that their photo viewer may not open. If people are meant to download and reuse your pictures, as with press photos or wallpapers, offer a JPG link beside the image.
Frequently asked questions
How much smaller will the AVIF be?
It depends on the picture, but photos are commonly much smaller than the JPEG at a similar visual quality.
Can every browser open AVIF?
All current major browsers can. Very old browser versions cannot, so sites that must support them should keep a JPEG fallback.
Why does AVIF conversion take longer?
AVIF encoding does more work per image than JPEG or WebP, so large photos need a few seconds.
Is AVIF output a paid feature?
No. AVIF output is free on every plan.
Should I delete the JPGs after converting?
No. Keep them as masters. The AVIF is a delivery copy, and if you later want a different size or a newer format you should start again from the JPG, not from the AVIF.
Does the AVIF keep the camera data from my JPG?
Not by default. Camera settings, date and location are removed during conversion. You can choose to keep them, or to keep everything except the location, in the editor.
