How do I judge AVIF quality?

Compare on the slider. Do not reuse a JPEG quality number by habit. AVIF at the same number can look softer or sharper depending on the photo.

Is AVIF smaller than WebP?

Often. The landscape demo is 9.2 MB as JPEG, 960 KB as WebP, and about 850 KB as AVIF.

Why is AVIF slow on my laptop?

AVIF encode is heavier than JPEG or WebP. Keep the tab open. Older machines take longer.

Do AVIF files get uploaded?

No. Encoding runs on your device.

Can I convert JPEG to AVIF?

Yes. Set output to AVIF, compress, then download a .avif file.

What browsers open AVIF?

Current Chrome, Edge, Firefox, and Safari open AVIF. If you must support an old in-app WebView, ship WebP as well.

Can I batch AVIF encodes?

Yes. A large batch will take longer than WebP. Compress fewer files at once if the tab heats up.

AVIF compressor

Encode AVIF in the browser. It is usually smaller than WebP, and slower on older laptops. Compare on the slider, then download. Files are not uploaded.

How to encode AVIF

When AVIF is worth the wait

Use it for a hero or a gallery when encode time is fine. WebP is the faster default.

AVIF

Usually the smallest photo file. Slower on older hardware.

WebP

Faster encode. Good enough for most pages.

JPEG

Use when a CMS or email still wants .jpg.

PNG

Keep for flat graphics, not camera photos.

See AVIF against the WebP demos

The slider uses the WebP samples. The AVIF note on the landscape is the extra encode.

9.2 MB → 960 KB WebP. AVIF of this frame lands near 850 KB; compare both.
