What is AVIF, the Next-Generation Image Format Available in Webflow?
In recent years, with the increase of rich content on web pages, page loading speed has become increasingly important. Image files, in particular, significantly affect the overall page size and directly impact website performance. This article provides a detailed introduction to AVIF (AV1 Image File Format), a new technology that surpasses traditional image formats such as JPEG, PNG, and WebP.
What is AVIF?
AVIF is a royalty-free image format based on AV1, a highly efficient video compression technology. It was developed by the Alliance for Open Media (AOMedia), which includes major companies like Google, Amazon, and Netflix, and is provided as open-source.
Benefits of AVIF
AVIF offers the following advantages for website owners and developers.
High Compression Ratio and High Image Quality Retention
It can reduce file sizes by up to 95% compared to JPEG and up to 30% compared to WebP. Despite its high compression ratio, it achieves superior image quality than both JPEG and WebP.
It can also handle images with higher quality and smaller file sizes compared to GIF.

Versatile Feature Support
It supports alpha channels (transparency), replacing transparent PNGs, and HDR color. This enables the creation of designs by layering and blending two images, or producing realistic visual experiences that enhance the user experience.
Lossless and Lossy Compression Options
Lossless compression refers to a method where an image can be restored to its original state after being compressed. Lossy compression, on the other hand, refers to a compression method where an image cannot be restored to its original state once compressed.
Traditionally, it was necessary to choose a compression method based on its intended use. However, since AVIF supports both, the need to choose between lossless or lossy compression has been eliminated.
AVIF vs. WebP: Which Should You Choose?
While WebP is also an excellent next-generation format, AVIF and WebP have the following differences:
If you prioritize high image quality and high compression, AVIF is the optimal choice. WebP, on the other hand, boasts extensive browser support as its strength.
AVIF Support in Webflow
Webflow has introduced AVIF image support to improve site performance. Webflow users can directly upload AVIF images or convert existing images to the AVIF format. Below, we will explain how to convert images uploaded to Webflow to AVIF.
