What Is AVIF? Browser Support & How to Convert
AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec, developed by the Alliance for Open Media (AOMedia). It offers significantly better compression than JPEG and WebP while maintaining excellent image quality. In this guide, we will explain what AVIF is, which browsers support it, and how to convert your images to AVIF.
What Is AVIF?
AVIF is an open, royalty-free image format that uses the AV1 video codec for image compression. It was first released in 2019 and has rapidly gained adoption due to its superior compression efficiency.
Superior Compression
AVIF files are typically 50% smaller than JPEG and 20% smaller than WebP at the same visual quality. This translates to faster page loads and lower bandwidth costs.
High Dynamic Range (HDR)
AVIF supports HDR and wide color gamuts (up to 12-bit color depth), making it ideal for photography and media-rich websites.
Transparency & Animation
Like PNG and WebP, AVIF supports alpha transparency. It also supports animated images, serving as a modern alternative to GIF.
Browser Support
As of early 2026, AVIF is supported by all major browsers:
- Google Chrome: Supported since version 85 (August 2020)
- Mozilla Firefox: Supported since version 93 (October 2021)
- Safari: Supported since version 16.4 (March 2023)
- Microsoft Edge: Supported since version 121 (January 2024)
AVIF now has over 95% global browser coverage, making it safe to use for most web projects. For the remaining browsers, you can provide JPEG or WebP fallbacks using the HTML picture element.
3 Ways to Convert Images to AVIF

Upload your JPG, PNG, or WebP file. Select AVIF as the target format. Click "Start Conversion" and download the result.
2. Command-Line Tools (FFmpeg / libavif)
For batch processing or automation, you can use command-line tools. FFmpeg supports AVIF encoding with the libaom-av1 codec. The libavif library also provides the avifenc tool for direct AVIF encoding.
3. Image Editing Software
Adobe Photoshop (2024+) and GIMP (2.10.32+) support AVIF export natively. In Photoshop, use File > Export > Save for Web and select AVIF. In GIMP, use File > Export As and choose AVIF from the format list.
