Introduction
As a web developer or digital marketer, you face the challenge of choosing the right image formats to optimise your websites performance and enhance user experience. We all know about JPEG's and PNG's but there are two new kids on the block; AVIF and WebP. With AVIF and WebP becoming more popular you're probably asking yourself: "Should I use AVIF or WebP images?"
Both formats offer significant advantages over traditional formats, but understanding their differences can help you make an informed decision. Let’s dive into the specifics of AVIF and WebP, and explore which is the best file format to use on your website.
What is WebP?
WebP is an image format developed by Google to create small, high-quality images for the web. It supports both lossy and lossless compression, as well as alpha transparency. WebP can reduce image file sizes significantly compared to traditional formats like JPEG's and PNG's. This will improve your user’s experience on your site by improving load times, while also improving your search rankings
Key Features of WebP:
- Small file sizes
- High-quality images
- Supports transparency
- Compatible with most major browsers
What is AVIF?
AVIF, or AV1 Image File Format, is a newer image format developed by the Alliance for Open Media. It offers even better compression and quality than WebP, creating higher quality images at a smaller file size. AVIF supports HDR (High Dynamic Range) imaging, providing a wider range of colours and better brightness levels.
Key Features of AVIF:
- Superior compression efficiency
- Higher-quality images
- Supports HDR
- Supports transparency
- Less browser support compared to WebP
