# Convert AVIF to PNG

AVIF images saved from websites often will not open in older editors, office apps or Windows tools. Convert them to PNG, which every program opens, and keep transparent backgrounds.

**Quick answer:** To convert AVIF to PNG, add the .avif files and press Convert to PNG. The browser decodes each AVIF and writes a lossless PNG, keeping any transparency, so nothing more is lost. PNG files are several times larger than AVIF. Nothing is uploaded.

## How to use it

1. Choose one or more .avif images.
2. Press Convert to PNG.
3. Check the results; transparent images stay transparent.
4. Download the PNGs, as a ZIP if there are several.

## Why PNG rather than JPG

AVIF supports transparency, and many AVIF images on the web are logos, stickers and cut-outs. PNG keeps that transparency and stores the decoded image without further loss, which suits editing, slides and documents. For photos you only want to share, [AVIF to JPG](https://sharelargefilesfree.com/tools/avif-to-jpg) gives much smaller files.

## What AVIF is

AVIF is an image format based on the AV1 video codec. It compresses photos better than JPG and even WebP, so sites use it to load faster. Current Chrome, Edge, Firefox and Safari (16 and later) display it, but many desktop apps, older phones and upload forms still do not accept it.

## Expect bigger files

A 100 KB AVIF photo can become a PNG of several MB, because PNG is lossless and was not designed for photographs. That is normal. To make the PNG smaller afterwards, use [Compress PNG](https://sharelargefilesfree.com/tools/compress-png). The conversion runs in your browser, so your images stay on your device.
