AVIF converter

AVIF gives you the smallest files of any format on this site, which is exactly why you sometimes need to leave it: the rest of the software world is still catching up. Use the pairs below to publish AVIF for modern browsers or to unwrap an .avif somebody sent you into something your tools accept.

What is AVIF?

AVIF (AV1 Image File Format) is the newest mainstream image format, published by the Alliance for Open Media in 2019 on top of the royalty-free AV1 codec. It delivers the strongest compression of any widely deployed format, especially at low and medium quality, and adds an alpha channel, HDR and 10/12-bit color. Browser support landed in Chrome 85, Firefox 93 and Safari 16, but much desktop software still cannot open an .avif file.

Common questions about AVIF

What is an AVIF file?
AVIF is a modern image format based on the AV1 video codec. It usually delivers smaller files than JPG, PNG, or even WebP at the same visual quality, and it handles wide color and HDR, transparency, and animation. The catch is that it's newer, so some older apps and editors still can't open it, which is when you convert it to something more universal.
How do I open or convert an AVIF file?
If an app won't open your .avif, convert it. Drop it into hushvert and choose PNG, JPG, or WebP. The conversion runs in your browser with no upload, so the image never leaves your device. PNG gives a lossless copy that keeps transparency; JPG is the most widely accepted but drops transparency.
How do I make an AVIF from a PNG or JPG?
hushvert converts PNG, JPG, WebP, and HEIC into AVIF, all client-side in the browser. AVIF is a good target when you want the smallest possible file without much visible quality loss. These conversions all run locally, so your source image is never uploaded.
Is AVIF better than WebP or JPG?
For pure compression, AVIF generally beats both at the same quality, especially on detailed photos and gradients. The tradeoffs are encoding speed and compatibility: AVIF is newer and slower to encode, and not every tool reads it yet. If broad support matters more than file size, JPG or PNG is the safer target, and hushvert converts AVIF to all of them.
Does hushvert upload my AVIF file to convert it?
No. Every AVIF conversion (to PNG, JPG, WebP, and from PNG, JPG, WebP, HEIC) runs in your browser through WebAssembly. Nothing uploads, which you can confirm in airplane mode or the Network tab, or via the live demo on our /privacy-proof page.
