Introduction
You upload an image to a modern website and notice the file ends in .avif instead of .jpg or .png. Your browser shows it fine, but when you try to download and open it in your photo editor, you get an error. AVIF is the newest mainstream image format, and it is showing up more and more across the web. In this article we break down what AVIF actually is, why big platforms like Netflix and Google are pushing it, where it makes sense to use it, and how to convert AVIF files to PNG or JPG when you need to edit or share them.
Why This Happens
AVIF stands for AV1 Image File Format. It is built on the AV1 video codec, which was developed by the Alliance for Open Media as a royalty-free alternative to older codecs. The big win with AVIF is compression efficiency. An AVIF file can be half the size of a WebP and up to ten times smaller than a JPEG at similar visual quality, thanks to advanced features like 10-bit color depth, HDR support, and film grain synthesis. Netflix, Google Images, and WordPress all serve AVIF to compatible browsers because it cuts bandwidth bills dramatically. The catch is compatibility. AVIF is supported in Chrome, Firefox, Edge, and Opera, but Safari only added full support recently, and many image editors, social platforms, and older apps still draw a blank when they see the format.
3 Solutions
Solution 1: Serve AVIF on your website with a JPG fallback. Use the HTML picture element to offer AVIF to modern browsers and JPG to older ones. Best of both worlds for web performance, since visitors with Chrome or Firefox get the tiny AVIF file while Safari and older browser users still see a working image. This approach is what Netflix and WordPress use in production, and it lets you cut bandwidth without sacrificing compatibility.
Solution 2: Convert AVIF to PNG for editing. When you need to open an AVIF in Photoshop or GIMP, run it through an piczen AVIF to PNG converter first. PNG preserves full quality and any transparency the AVIF contained, so you can edit every pixel without loss. This is the right move when you downloaded an AVIF from a website and need to composite it into a design or retouch it in a desktop editor that does not support AVIF natively.
Solution 3: Convert AVIF to JPG for sharing. For social media or email, convert AVIF to JPG so recipients can open the file without any special software. Most social platforms and messaging apps still cannot handle AVIF, and sending one often results in a blank preview or a download error. A quick conversion to JPG before sharing saves the recipient from having to figure out why the image will not open.
Step-by-Step Guide
If you downloaded an AVIF file and need to open it, the fastest path is a browser converter. Open the avif to png tool in any modern browser. Drag your AVIF file onto the page or click to browse. The tool decodes the AVIF using a server-side decoder and re-encodes it as PNG, which preserves every pixel of the original including any transparency. Click Download and you have a PNG that opens in any image editor on earth, from Photoshop to GIMP to the built-in Photos app on your phone. If you are a web developer looking to serve AVIF on your own site, the best approach is to use a CDN like Cloudflare or imgix that auto-converts your JPG uploads to AVIF on the fly. Pair the AVIF with a JPG fallback in a picture element so older browsers get a working image instead of a blank screen. Test your setup in multiple browsers, including Safari and older Chrome versions, since AVIF rendering can vary slightly across engines and some edge cases like animated AVIF are not universally supported yet.
Pros and Cons
AVIF wins on file size and quality. For a typical product photo, an AVIF at 50 KB often looks better than a JPG at 150 KB, which is a huge win for page load times and mobile data usage, especially for users on slow cellular connections in emerging markets. It also supports modern features like 10-bit color depth, HDR, wide color gamut, and film grain synthesis that JPG simply cannot match, making it the format of choice for streaming platforms like Netflix. The downside is the compatibility gap. Older browsers, most image editors, and a surprising number of social platforms still do not handle AVIF natively, which means you need fallbacks for a seamless experience. Safari only added full AVIF support recently, and many mobile gallery apps still draw a blank. For web delivery with proper fallbacks, AVIF is a clear win that can cut your bandwidth bills dramatically. For files you need to edit, share, or print, convert to PNG or JPG first. The smart approach is to serve AVIF on your website with fallbacks and keep PNG or JPG copies for editing and sharing outside the browser.
