Convert AVIF to JPG

How to convert AVIF to JPG

1. Drop your AVIF files into the box above, or click to browse. You can also paste with Ctrl+V.
2. Adjust quality or resizing under Conversion settings if you need to. The defaults suit most photos.
3. Conversion starts automatically and runs on your device — watch the progress bar for each file.
4. Download files individually, or grab everything as a ZIP.

What changes when you convert AVIF to JPG

AVIF is the most efficient still-image format in general use, and converting away from it always costs bytes. It is built on AV1, a video codec from 2018, and it routinely produces files half the size of JPEG at comparable quality — sometimes better than that on flat or synthetic images. So the first thing to expect here is that the file gets larger, often by a factor of two or three.

The second thing to expect is a reduction in colour precision. AVIF supports 10-bit and 12-bit colour per channel; JPEG is 8-bit only. On most photographs this is invisible. On images with long smooth gradients — sunsets, studio backdrops, soft shadows — the reduction can introduce visible banding, because 8 bits gives you 256 steps per channel where 10 bits gives 1024.

HDR is the harder loss. AVIF can carry genuine high dynamic range, and JPEG has no mechanism for it. An HDR AVIF converts to a standard-range image: the highlights that would have opened up on a capable display are simply mapped down, permanently.

Transparency disappears too, because JPEG has no alpha channel. Any transparent area gets filled with the matte colour you choose.

Why do it at all? Because support outside the browser is thin. Every current browser reads AVIF, but a great deal of desktop software, print workflow and corporate tooling does not, and encoding AVIF is slow enough that many pipelines never adopted it. If a file has to open somewhere unpredictable, JPG remains the format with no questions attached.

What is preserved

• Pixel dimensions and the visible content
• The standard dynamic range rendering of the image

What is lost

• Transparency — JPEG has no alpha channel
• 10-bit and 12-bit colour depth, reduced to 8-bit
• HDR: AVIF can carry high dynamic range, JPEG cannot represent it at all
• Wide colour gamuts beyond sRGB in most workflows
• Animation, where the AVIF contains an image sequence

What is altered

• Transparent pixels are composited onto the matte colour you choose
• The file grows, typically to two or three times the AVIF, because JPEG is far less efficient
• Banding can appear in smooth gradients that relied on 10-bit precision

When not to convert AVIF to JPG

Do not convert if the destination reads AVIF. Every current browser does. For anything going onto a web page, converting away from AVIF is a straightforward downgrade in both size and quality.

Do not convert if the image has transparency or is HDR. Both are lost outright, and neither can be recovered afterwards.

Do not convert to JPG when WebP would do. WebP is roughly 25–30% smaller than JPEG at matching quality, supports transparency, and is read by every browser and most modern software. It is the better middle ground when full JPEG compatibility is not strictly required.

Do not convert as a way to make a file smaller. It will not — AVIF is already better at that than anything JPEG can do.
