How to Convert AVIF to JPG/PNG: A Complete Compatibility Guide

Learn how to convert AVIF images to JPG or PNG formats for compatibility on legacy platforms, emails, and older web browsers.

What is AVIF and why does it fail to open?

AVIF (AV1 Image File Format) is a modern, next-generation image format that compresses files up to 50% better than standard JPGs. It supports transparency and high dynamic range colors. Because of this, many modern websites use AVIF to speed up their page loading times.

However, AVIF has a major drawback: compatibility. Many legacy platforms, email clients (like older versions of Outlook), word processors, and image editors cannot read AVIF files. If you download a web image and find it saved as `.avif`, you will often need to convert it to standard JPG or PNG to view or upload it elsewhere.

When to choose JPG vs PNG for AVIF conversion

When converting your AVIF image, select the output format that matches how the image will be used:

  • Convert AVIF to JPG: Best for photos and general web sharing. JPG has 100% compatibility and produces light files, but it does not support transparent backgrounds.
  • Convert AVIF to PNG: Best for logos, screenshots, and graphics. PNG is lossless and supports transparency, but the file size will be significantly larger.

How to convert AVIF to JPG or PNG online free

With PhotoTools, you can convert AVIF files locally. Your original images never leave your computer, avoiding the security risks of online upload converters.

  1. Drop your AVIF files into the PhotoTools Converter.
  2. Select your output format (JPG or PNG).
  3. If converting to JPG, adjust the quality slider (90% is recommended).
  4. Click Convert all, and download the converted images.

Technical details: how browser-based conversion works

Our converter uses the browser's native image decoding engine to read the AVIF pixel stream. It then draws these pixels onto an OffscreenCanvas and exports them as a new file in your chosen target format.

Because this happens entirely on your local machine, it is fast and secure. It also strips out unnecessary container metadata in the process, resulting in a cleaner output file.

FAQ

Why does my converted JPG have a white background?

AVIF supports transparent pixels, but the JPG format does not. When you convert a transparent AVIF to JPG, the transparent areas are filled with white. To preserve transparency, convert the AVIF to PNG or WebP instead.

Will I lose quality when converting AVIF to JPG?

JPG is a lossy format, so there is a minor theoretical loss of quality. However, at a quality setting of 90% or higher, the visual difference is completely indistinguishable to the human eye.

Does Windows support AVIF out of the box?

Windows 10 and 11 do not fully support AVIF natively in all default applications unless you install the AV1 Video Extension from the Microsoft Store. Converting AVIF to JPG is the fastest way to make the file viewable across all devices.

Frequently asked questions

Why did my transparent background turn white after conversion?

JPG does not support transparency. If your source AVIF contains transparent areas, convert it to PNG or WebP to keep the transparency intact.

Is there a loss of quality when converting AVIF to JPG?

Converting to a lossy format like JPG introduces minor detail discard. Setting the export quality to 90% or higher keeps this change visually invisible.

Can I batch-convert AVIF files?

Yes. You can drop multiple AVIF files into the converter and download them individually or as a compressed ZIP file.
