AVIF to JPG

Why convert AVIF to JPG

AVIF is a newer image format, built on the AV1 video format from the Alliance for Open Media. It makes very small files, so more and more websites use it, and saving a picture from one can leave you with an .avif file. Many photo editors, office programs, print services and upload forms don’t open AVIF yet. JPG opens almost everywhere.

How to convert

1. Choose up to 30 AVIF images, each up to 50 MB. You can also drop them on the box or paste one.
2. Leave the quality at 90, or change it (below).
3. Press Convert to JPG, then download each JPG, or all of them together as a ZIP.

Your browser reads the AVIF

The tool uses your browser’s own AVIF support. That means current Chrome, Edge and Firefox, or Safari 16 or later; on an iPhone or iPad, Safari’s version follows iOS, so iOS 16 or later. An older browser can’t read AVIF at all. The tool then says the file couldn’t be read rather than making a broken JPG, and updating the browser fixes it.

Choosing the quality

The quality number, from 1 to 100, sets how much detail the JPG keeps. At 90, the default, a photo looks like the AVIF on a screen. Lower it for a smaller file with softer detail. AVIF squeezes pictures much harder than JPG can, so expect the JPG to be noticeably bigger than the AVIF at any quality that still looks good.

What changes in the file

• Transparency. JPG has none, so see-through areas become white.
• Bright HDR pictures. Some AVIF images hold a wider range of brightness than a JPG can. They come out as an ordinary JPG, and the brightest highlights may look flatter.
• Hidden details. Metadata such as camera details isn’t copied into the JPG. Colors are converted to sRGB, the standard range screens use.
• Names. Each JPG keeps its AVIF’s name with a new ending: banner.avif becomes banner.jpg. A file that can’t be read gets its own message, and the rest still convert.

The size in pixels stays the same. To make the pictures smaller as well, use the Image Resizer, which also opens AVIF and saves JPG.
