AVIF gives the smallest files of any format browsers can show, which makes it the usual pick for hero images and photo-heavy pages. Most browsers can display it but cannot create it, so this page brings its own encoder and converts each image in this tab. Your images are never uploaded.
How to use it
- Choose images, drop them here, or paste one (Ctrl+V).
- AVIF is already selected. Adjust the quality slider if needed.
- Wait for each image to finish (the encoder loads once, then it is quicker), and download.
When to choose something else
- You need it to open everywhere. Image to WebP is nearly as small and more widely supported.
- It is going to an email or upload form. Keep a JPG. If you already have an AVIF, AVIF to JPG turns it back.
Frequently asked questions
Does this work in Chrome and Firefox?
Yes. Only Safari can write AVIF on its own, so in Chrome, Edge and Firefox the page loads a 3.5 MB AVIF encoder (libavif) the first time you convert. It runs on your device; nothing is uploaded.
Why is it slower than converting to JPG or WebP?
AVIF compression does much more work per pixel. A 12 megapixel photo can take several seconds on a laptop and longer on a budget phone. Resize very large photos first if you are converting a batch.
How much smaller is AVIF than JPG?
Often around half the size at similar visual quality for photos, and smaller than WebP too. Flat graphics and screenshots save less.
Will everyone be able to open the AVIF?
Current Chrome, Edge, Firefox and Safari display it, so it is fine for websites. Older desktop apps, some email clients and many upload forms still reject AVIF, so keep a JPG for those.
Is transparency kept?
Yes. AVIF supports an alpha channel, so transparent PNG, WebP and SVG images stay transparent.
