AVIF vs WebP: What is the Best Image Format for Your Website?

October 12, 2025
If your website is packed with high-quality images, you already know how much of an impact those files can have on your page load speed. Slow websites don’t just frustrate users—they also rank lower on Google. That’s why choosing the right image format is critical for site performance and SEO. Today, we’re taking a closer look at two of the most modern and efficient image formats available: AVIF vs WebP.
Both formats offer excellent compression and quality, but they’re not exactly the same. Whether you’re a developer, a digital marketer, or a small business owner running a WordPress site, understanding the difference between AVIF vs WebP can help you make smarter decisions about how you optimize your images.
What is WebP?
WebP is a modern image format developed by Google. It was released in 2010 to improve upon traditional formats like JPEG and PNG. WebP supports both lossy and lossless compression, meaning it can reduce file size significantly while maintaining visual quality.
Benefits of WebP:
- Up to 30% smaller file sizes compared to JPEG and PNG
- Supports transparency and animation
- Broad browser support, including Chrome, Firefox, Edge, Safari, and Opera
- Faster loading times on most websites
Limitations of WebP:
- Doesn’t support HDR (High Dynamic Range)
- Image quality at very low compression rates can be inconsistent
- Not as efficient as newer formats like AVIF
WebP is ideal for sites that need a balance between quality and speed without worrying about older browser compatibility.
What is AVIF?
AVIF stands for AV1 Image File Format. It’s a newer format based on the AV1 video codec and was introduced around 2019. AVIF is designed to deliver superior compression, allowing websites to load even faster without sacrificing image quality.
Benefits of AVIF:
- Even smaller file sizes than WebP
- Better image quality at lower bitrates
- Supports HDR, transparency, and wide color gamuts
- Open-source and royalty-free
Limitations of AVIF:
- Slower encoding speed compared to WebP
- Browser support is growing, but not yet universal
- Some content management systems and older image tools may not support it out of the box
If you’re optimizing for the future and want cutting-edge performance, AVIF is a strong contender.
As you can see, AVIF vs WebP boils down to a trade-off between cutting-edge compression (AVIF) and faster, easier implementation with broad support (WebP).
When Should You Use WebP?
Choose WebP if you:
- Need fast loading images on most browsers
- Want a format that’s easy to integrate into your current workflow
- Are looking for better performance than JPEG or PNG, without complicating setup
It’s especially useful for WordPress sites, Shopify stores, and web platforms with built-in WebP support.
When Should You Use AVIF?
In many cases, the best solution isn’t choosing just one. Serving AVIF images when the browser supports them and falling back to WebP for broader compatibility is an ideal solution. Tools like Cloudflare, ImageKit, or Contentful can help with automatic image format negotiation.
This approach ensures users on modern browsers enjoy faster load times, while others still receive optimized images.

Final Thoughts
The AVIF vs WebP debate isn’t about picking a winner—it’s about picking the best solution for your audience and site setup. If you’re running a content-heavy website, e-commerce platform, or portfolio, switching to either format can drastically cut image weight and boost performance.
- Use WebP if you want something reliable, fast, and widely supported.
- Use AVIF if you’re aiming for next-level optimization and are ready to invest in a future-proof strategy.
Use both if you want the best of both worlds and your tech stack can support it.
