AVIF is the newest and most efficient of the web image formats, built on the AV1 video codec. It routinely beats JPG by 50% at the same quality, which is why sites that care about page speed have started serving it — and why you now have a file that browsers display perfectly and nothing else will touch.

The support gap here is wider than it was with WebP. Windows needs an extension from the Microsoft Store, Photoshop needs a plugin, older versions of macOS cannot preview it, and most upload forms have never heard of it. Converting to JPG is the pragmatic move whenever the file has to leave the browser.

Decoding happens in your browser using the same AV1 code the browser itself uses, so nothing is uploaded and there is no file limit.

How to convert AVIF to JPG

  1. Add your AVIF files. Drag them onto the box above, click to browse, or paste an image straight from your clipboard. You can add as many at once as you like.
  2. Adjust the settings if you need to. The defaults suit most images. Raise the quality slider if the image contains text or flat colour. Pick a background colour if your image has transparent areas.
  3. Download the JPG file. Each file gets its own download button as soon as it finishes, and you can pull the whole batch down as a single ZIP.

What changes when you convert AVIF to JPG

Every format conversion involves trade-offs, and vague tools hide them. Here is exactly what happens to your image in this particular conversion.

  • JPG has no transparency channel, so any transparent areas are filled with a solid colour. White is used by default and you can pick a different colour before converting — this is the single most common surprise when going from AVIF to JPG.
  • Both formats are lossy, so the file is being re-compressed. We decode AVIF at full fidelity and re-encode once at your chosen quality, which keeps generational loss to a minimum, but converting back and forth repeatedly will visibly degrade an image.

What you give up in the conversion

Two things, and only one of them usually matters. AVIF can store transparency and JPG cannot, so transparent areas are filled with a background colour you choose — convert to PNG or WebP instead if you need to keep them.

AVIF can also store high dynamic range and wider colour, which JPG cannot represent. If your file came from a photography workflow rather than a website, colours may look very slightly flatter after conversion. For an image saved from a web page this almost never applies, because the original was tuned for standard displays in the first place.

What happens to the file size

Measured, not estimated: two 1200 x 800 pixels references — a photograph and a flat-colour graphic — put through this converter.

Yours will differ: size depends more on what is in the picture than on the formats involved.

About AVIF (AV1 Image File Format)

AVIF is a modern format built on the AV1 video codec, producing the smallest files of any widely supported image format.

Where you probably got it: Downloaded from a modern website that serves next-gen images.

Strengths

  • Typically 30–50% smaller than JPG at visually identical quality
  • Handles transparency, HDR and wide colour gamut
  • Royalty-free and supported in all current browsers

Limitations

  • Encoding is computationally expensive — noticeably slower than JPG or PNG
  • Very little support outside browsers: most desktop and print software cannot open it
  • Can smear fine texture at aggressive settings

About JPEG (Joint Photographic Experts Group)

JPG is the lossy photographic format that has been the default for digital cameras and the web since 1992.

Support: Universal. If a program can open an image at all, it can open a JPG.

Strengths

  • Opens in literally every image viewer, editor, printer and web form ever made
  • Very small files for photographs, with a quality dial you control
  • Hardware-accelerated decoding on every phone and camera

Limitations

  • No transparency — transparent areas have to be flattened onto a solid colour
  • Lossy: each re-save discards a little more detail permanently
  • Blocky artefacts around sharp edges, text and flat colour

Is it safe to convert AVIF online?

Here, yes — and you can check rather than trust. Open your browser’s developer tools, switch to the Network tab and convert a AVIF file: no request carrying your image is made. Disconnect from the internet after this page has loaded and the converter still works, which would be impossible if a server were doing the conversion.

That is worth verifying wherever you convert, because most online converters do upload, and AVIF files are so often personal photos and documents people would not hand to a stranger. Once a file is on somebody else’s server you are relying on a privacy policy rather than on anything you can observe. We wrote up how to tell a safe converter from a risky one in more detail.

Frequently asked questions

Why will Windows not open my AVIF file?

Windows 10 and older Windows 11 builds do not decode AVIF without the AV1 Video Extension from the Microsoft Store. Even with it installed, individual applications may still refuse the format. Converting to JPG sidesteps the whole problem, which is generally quicker than persuading every program on the machine to cooperate.

How much larger will the JPG be?

Commonly two to three times, because AVIF compresses considerably better. A 150 KB AVIF might become a 400 KB JPG at visually equivalent quality. Lowering the quality slider closes much of that gap before any visible difference appears.

How do I convert AVIF to JPG?

Drag your AVIF file onto the box above, or click it to browse. The conversion starts immediately in your browser and the JPG download appears within a second or two for most images. You can drop in a whole folder of files at once and download them together as a ZIP.

Are my AVIF files uploaded to a server?

No. The conversion happens locally in your browser, so your files are never transmitted anywhere — the tool even works with the network disconnected once the page has loaded. That is also why there is no file size or file count limit: nothing costs us anything per conversion. The practical ceiling is your own device's memory, which on a phone means very large images may fail.

Does AVIF to JPG keep transparency?

It cannot — JPG has no transparency channel at all. Transparent pixels are filled with a background colour, which defaults to white. Use the background colour picker before converting if you need black or a brand colour instead. If you need to keep the transparency, convert to PNG or WebP rather than JPG.

Will converting AVIF to JPG reduce the quality?

A little. Both formats are lossy, so the image is decompressed and re-compressed once. We decode at full fidelity and encode a single time at your chosen quality, so a one-off conversion is close to invisible — but avoid converting the same image back and forth repeatedly.

What is the difference between AVIF and JPG?

AVIF is a modern format built on the AV1 video codec, producing the smallest files of any widely supported image format. JPG is the lossy photographic format that has been the default for digital cameras and the web since 1992. In practice the choice comes down to compatibility: all current browsers decode AVIF. Outside the browser, support is still thin — which is usually why you need it converted. Meanwhile universal. If a program can open an image at all, it can open a JPG.
