Goodbye JPG – Hello AVIF!

With circa 94% browser compatibility and 50% better compression than JPEG, AVIF image file format is ideal for web performance, SEO, and High Dynamic Range (HDR) images.
14 Feb 2026

In large organisations, file formats are rarely discussed at board level.

Yet they influence performance, sustainability and digital consistency across every market.

For years, JPG has been the default delivery format for corporate imagery. It’s familiar, widely supported and operationally simple.

However, familiarity is not the same as efficiency.

As digital ecosystems expand across regions, platforms and devices, image infrastructure becomes a governance issue.

The next stage in controlled brand delivery is the adoption of AVIF as the primary image format.

Why Change?

AVIF delivers materially smaller file sizes compared with JPG, while maintaining or improving image quality.

In practical terms this means:

• Faster page load times across global markets
• Reduced bandwidth usage
• Improved performance scores for websites
• Lower storage requirements across digital asset systems
• Reduced carbon footprint from data transfer

For organisations managing thousands of images across multiple regions, these efficiencies compound.

This is not a creative shift.

It’s a structural one.

 

Global Support

With approximately 93 to 94 percent global browser compatibility and materially stronger adoption across modern devices, AVIF is no longer an experimental format.

It delivers up to 50 percent better compression than JPEG at comparable visual quality, directly improving page speed metrics and supporting stronger search performance. Smaller file sizes contribute to faster Largest Contentful Paint, improved Core Web Vitals scores and reduced crawl overhead, all of which influence visibility in competitive search environments. The format is also well suited to High Dynamic Range imagery without inflating bandwidth requirements.

For implementation best practice, the HTML element can be used to provide a JPG fallback for the remaining 6 to 7 percent of users operating older browsers.

In practical terms, global compatibility is now operationally viable, provided structured fallback rules are in place.

Governance Implications

Standardising delivery in AVIF format allows:

• More consistent performance across territories
• Reduced reliance on local optimisation practices
• Simplified asset management rules
• Greater control over file size without regional compromise

When imagery is treated as infrastructure, performance becomes measurable. Faster load times, improved technical SEO signals and reduced data transfer overhead translate into tangible ranking stability across markets, particularly for organisations operating multiple regional domains or high-volume leadership pages.

Considerations

There are, however, transitional factors to manage:

• Legacy systems or older browsers may not support AVIF without fallback formats
• Some internal DAM platforms may require configuration updates
• Editing workflows are still more commonly JPG-based in certain regions

For this reason, structured rollout and compatibility auditing are essential.

Change in format is not cosmetic.

It reflects digital maturity.

I’ll be introducing AVIF as the primary delivery format for corporate photography assignments, with appropriate transitional safeguards where required.

If you are reviewing digital performance or asset governance across regions, I’m happy to discuss how structured image delivery can support that objective.
