Does the JPG keep transparency?

No. JPG has no alpha channel, so any transparent areas in the AVIF are flattened onto a solid background when the canvas is encoded.

Will the JPG be larger than the AVIF?

Usually, yes. AVIF compresses more aggressively than JPG at the same visual quality, so the same picture often takes more bytes as a JPG. The trade is broader compatibility.

Is there any quality loss?

The AVIF is decoded to exact pixels, then re-encoded as JPG at maximum quality. JPG is lossy, so fine detail and sharp edges can pick up faint artifacts, though for photos the difference is hard to see.

Can it convert animated AVIF?

Only the first frame. A JPG is a single still image, so animation isn't preserved.

Do my images get uploaded anywhere?

No. Decoding and encoding run entirely in your browser tab. Nothing is sent to a server.

AVIF to JPG

Decodes the AVIF and re-encodes it as a JPG your apps can open.

What this does

AVIF packs an image into the AV1 codec, which keeps file sizes small but isn't decodable everywhere a plain photo needs to go. This converter reads each AVIF frame in the browser, paints it onto a canvas, and re-encodes the pixels as a baseline JPG that any image viewer, editor, or upload form will accept.

Decoding happens on your own machine through the browser's built-in AVIF support, so the images never leave the page. Drop a single file or a whole batch; each one is converted in turn and offered back individually or bundled into a single zip.

How it works

1Drop your AVIF images, or click to pick them.
2Each file is decoded and re-encoded to JPG in your browser.
3Download each JPG, or grab them all as a zip.
