What is AVIF? — The Next-Generation Image Format
AVIF (AV1 Image File Format) is the most efficient image format available today. It delivers up to 50% smaller file sizes than JPEG with superior quality, supports HDR and wide color gamut, and is quickly becoming the go-to format for high-performance web images.
What is AVIF Format?
AVIF stands for AV1 Image File Format. It is derived from the AV1 video codec developed by the Alliance for Open Media — a consortium including Google, Apple, Mozilla, Microsoft, Netflix, and Amazon. AVIF was standardized in 2019 and has quickly gained adoption as the most efficient still image format.
AVIF uses cutting-edge compression algorithms to achieve up to 50% smaller file sizes than JPEG while maintaining equal or better visual quality. It supports lossless and lossy compression, full transparency, HDR (High Dynamic Range), and wide color gamut — making it technically superior to every older format including WebP.
As of 2024, AVIF is supported by Chrome, Firefox, Safari (since version 16), and Edge — covering over 93% of global web users. Major platforms including Netflix, Google, and Shopify already use AVIF to serve images.

When Should You Use AVIF?
Use AVIF for: Web images where maximum compression is the priority. If your audience uses modern browsers (Chrome, Firefox, Safari), AVIF will deliver the smallest possible file sizes with excellent quality — faster page loads, lower bandwidth usage, and better Core Web Vitals scores.
Don't use AVIF for: Images that need to work in all software (use JPG/PNG), print production (use TIFF), or when encoding speed is critical (AVIF encoding is slower than WebP).

Frequently Asked Questions About AVIF
Is AVIF better than WebP?
For compression efficiency, yes — AVIF produces files 20–30% smaller than WebP at the same quality. However, WebP has slightly broader browser compatibility. For modern websites targeting current browsers, AVIF is the better choice.
Is AVIF supported by Safari?
Yes — Safari has supported AVIF since version 16 (released in 2022), which is available on iOS 16+ and macOS Ventura+. Most current Apple devices support AVIF.
Can I open AVIF files on Windows?
Windows 11 supports AVIF natively. On Windows 10, you may need to install the AV1 Video Extension from the Microsoft Store. Alternatively, convert AVIF to JPG or PNG using our free converter for universal compatibility.
Does AVIF support transparency?
Yes — AVIF supports full alpha channel transparency, similar to PNG and WebP. This makes it suitable for logos, icons, and any image that requires a transparent background.
