AVIF to JPG: Open AVIF Images Anywhere

You save a picture from a website, try to attach it to an email or open it in an older editor, and nothing happens. The file ends in .avif. AVIF is one of the newest image formats on the web, and it is excellent at keeping files small, but a lot of everyday software has not caught up. This guide explains what AVIF is, where it comes from, how to convert it to JPG with the AVIF to JPG Converter on this site, and how to pick settings so the result looks right the first time.

What AVIF is and why websites use it

Video technology, used for still pictures.

AVIF stands for AV1 Image File Format. It stores a still picture using the same compression as the AV1 video codec, inside the same kind of container that HEIC uses on iPhones. The result is a lossy format that usually keeps more detail than JPG at the same file size, and it supports transparency, wide colour and animation.

For a website, smaller images mean faster pages and lower bandwidth bills, so image services and content platforms send AVIF to any browser that says it can display it. That is why a photo that looked ordinary on a page lands in your downloads folder as .avif. Some phones and cameras can also save photos as AVIF to save storage space.

Why so many apps still reject AVIF files

Support arrived in browsers first.

Current versions of Chrome, Edge, Firefox and Safari all display AVIF, which is why the picture looked fine on the website. Desktop software moved slower. Older versions of Photoshop, Office, some photo viewers and a long list of upload forms on job portals, banks and print shops only accept JPG or PNG.

Renaming the file does not help. Changing photo.avif to photo.jpg only changes the label; the data inside is still AVIF, so an app that cannot read AVIF still refuses it, sometimes with a confusing error about a damaged file. The fix is a real conversion that decodes the AVIF and writes a new JPG.

Converting AVIF to JPG step by step

One file or a whole folder.

Open the AVIF to JPG Converter and drop the file onto the upload area. You can also choose a folder, paste an image with Ctrl+V, or paste the image address into the URL box if the site allows direct downloads. A single file shows a card with its size and pixel dimensions.

JPG is already selected under Output format, at the High preset of 90. Press Convert to JPG. The browser decodes the AVIF, draws it onto a canvas, and encodes a new JPG, which downloads with the same name and a .jpg extension. A before and after view shows both versions and their sizes.

For a batch, drop all the files at once. Each row shows its old and new size, a summary shows the total, and Download all saves converted-jpg.zip. Nothing is uploaded at any point, because the decoding happens in the browser itself.

Choosing quality, size and background

Three settings cover almost every case.

Quality decides the trade-off between size and detail. The presets are High (90), Medium (75) and Low (50), and the slider takes any value from 1 to 100. For photos you plan to print or edit, stay at 90. For email and chat, 75 to 85 is usually indistinguishable at normal size.

Expect the JPG to be bigger than the AVIF. That is not a mistake: AVIF compresses more efficiently, so the same picture needs more bytes as a JPG. If the file has to fit under a limit, enter a Max width such as 1600 pixels, or lower the quality a few steps.

AVIF can hold transparency, but JPG cannot. Transparent pixels are filled with the background colour you choose, white by default. If the image is a logo or sticker that must stay see-through, switch the Output format to PNG or WebP before converting.

Printing or editing: JPG at 90 or PNG.
Email and messaging: JPG at 75 to 85, max width 1600 to 2000 px.
Logos and stickers with transparency: PNG or WebP.
Upload forms with a KB limit: convert here, then use the Image Compressor with a target size.

Common problems and how to fix them

Most have a one-line answer.

A few issues come up again and again. None of them need special software.

The file will not open in the converter: your browser is too old to decode AVIF. Update Chrome, Edge, Firefox, or Safari to version 16 or later.
The JPG has a white box where the background was transparent: that is how JPG works. Pick PNG output, or choose a background colour that matches where the image will be used.
The camera details are missing: the browser gives the page only the pixels of an AVIF file, so EXIF data from the AVIF is not carried over.
The file came from an animated AVIF: only the first frame is saved in a JPG.
The colours look slightly flatter: some AVIF files use wide colour. Converting to standard JPG maps them into the usual sRGB range, which is what most screens show anyway.

When to keep the AVIF

Convert a copy, not the only copy.

If you run a website, AVIF is worth keeping for publishing, because it is often the lightest version of the image. Convert a copy to JPG for sharing and editing, and keep the original AVIF alongside it. Converting back and forth between lossy formats loses a little detail each time, so always work from the highest quality source you have.

For the reverse direction, the Image Compressor and the converters on this site can save WebP, which gives similar savings to AVIF and opens in every current browser. And if you only need to shrink the JPG you just made, the Image Resizer can hit an exact pixel size and a KB limit in one pass.
