AVIF Converter — Open & Convert .avif Files
AVIF (.avif) is a modern image format built on the AV1 video codec. It usually beats JPEG, WebP and even PNG on compression — crisp photos and graphics at a fraction of the size — which is why more and more websites serve it. The catch is that while current desktop and mobile browsers can display AVIF, plenty of applications still cannot: image editors, older viewers, some messaging and upload services, and default gallery apps on older systems. When a program refuses to open your .avif file, converting it is the fix.
Every converter below decodes your AVIF locally in the browser using a WebAssembly AVIF decoder. Your files are never uploaded, never stored, never seen by anyone — no account, no watermark, no limits, and it works offline once the page loads. Pick AVIF → JPG for the widest compatibility, AVIF → PNG for a lossless file with transparency, AVIF → WebP for another small web-friendly format, AVIF → JPEG XL for a next-gen format, or AVIF → PDF to make a document.

Frequently asked questions
What is an AVIF file?
AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec. It delivers smaller files than JPEG and WebP at comparable or better quality, supports transparency and HDR, and is increasingly used by websites to speed up image loading. Files use the .avif extension.
How do I open an AVIF image?
Current versions of Chrome, Firefox, Edge and Safari can display AVIF in the browser, and you can drop the file into any converter on this page to view or change it. If a desktop app or editor cannot open your .avif, convert it to JPG or PNG — those are universally supported.
Which format should I convert AVIF to?
Use JPG for maximum compatibility with any device or app. Use PNG when you need lossless quality or transparency. Use WebP or JPEG XL for another compact format, or PDF to turn images into a document. For sharing with people whose software you do not control, AVIF → JPG is the safe choice.
Are my AVIF files uploaded?
No. AVIF decoding and conversion run entirely in your browser with WebAssembly. Your images never leave your device — no uploads, no accounts, no watermarks and no usage limits, and it works offline once the page has loaded.
