Choosing the right image format can dramatically impact your website's loading speed and user experience.

If you're deciding between AVIF, JPEG, and WebP for your project, here's what you need to know to make the best choice.

AVIF: The Future of Image Compression

AVIF delivers the smallest file sizes among all three formats, typically achieving 10% better compression than WebP and up to 50% smaller files than JPEG.

This newer format supports advanced features like higher color depths, transparency, and HDR content, making it ideal for modern web applications and mobile apps.

To view AVIF files on Windows, install the AV1 Video Extension for native support in Microsoft Photos and File Explorer.

Best for: New projects, progressive web apps, and sites targeting modern browsers.

WebP: The Reliable Middle Ground

WebP offers excellent compression (20-35% smaller than JPEG) with broader browser support than AVIF.

It's supported by all major browsers since 2020, making it a safe choice for most websites while still providing significant performance benefits.

Windows users can add native WebP support by installing the WebP Image Extensions or WebP Codec.

JPEG: The Universal Standard

JPEG remains the most universally supported format across all devices and browsers.

Best for: Email campaigns, legacy systems, and maximum device compatibility.

Browser Support Comparison

AVIF: Chrome 85+, Firefox 93+, Safari 16+
WebP: All modern browsers (95%+ support).
JPEG: Universal support (100%).
