You're browsing a website, and it's loading slower than you'd expect. Why? Too many large images are dragging it down. We've all been there, and it’s frustrating. But what if there’s a better way to serve high-quality images online without slowing things down? Enter Next-Gen Formats.
These modern image formats are designed to solve the exact problem we’ve all encountered — how to display beautiful, detailed images without sacrificing speed. They’re smaller in size, faster to load, and better for both users and search engines.
What Are Next-Gen Formats?
Next-gen formats are newer image file types that are designed to offer better performance on the web compared to older formats like JPEG, PNG, or GIF. These formats are optimized to provide high-quality images while reducing file size, which helps improve website load times and overall performance.
In simpler terms, these formats allow you to show great-looking images without bogging down your website's speed. Netflix has put its faith in AV1, and others are following suit.
You’ve probably noticed how sluggish some websites become when they try to load a bunch of large images. Serving images in next-gen formats can help solve that problem.
In fact, search engines like Google now recommend websites implement these formats to boost performance, especially when it comes to dynamic site acceleration.

Common Types of Next-Gen Formats
Now that you have a sense of what next-gen formats are, let's look at some of the most popular types you'll come across:
- WebP: Created by Google, WebP is one of the most commonly used next-gen image formats. It provides excellent compression for both lossless and lossy images, meaning it can keep quality high while shrinking the file size dramatically.
- AVIF: AVIF is a relatively new format that offers even better compression than WebP. It supports features like high dynamic range (HDR) and provides better image quality at lower sizes. This makes it ideal for websites that want to deliver high-quality visuals without sacrificing speed.
- JPEG 2000: Although it's been around for a while, JPEG 2000 is still considered a next-gen format due to its superior compression and quality when compared to the older JPEG format.
- JPEG XL: JPEG XL is another emerging format designed to replace traditional JPEGs. It supports both lossless and lossy compression and promises high-quality images with smaller file sizes.
Each of these formats has its unique strengths, but WebP and AVIF are the most widely supported across browsers, which makes them the go-to choices for many web developers and designers.
Benefits of Using Next-Gen Formats
So, why should you bother with next-gen formats? The benefits are numerous, and they can have a significant impact on how your website performs and how users experience it.
1. Improved Website Load Speed
When you serve images in next-gen formats, you can drastically reduce the size of the files being loaded. Smaller files mean faster loading times, which can make your website feel snappier.
With so much content to consume online, users tend to abandon slow-loading websites. Using next-gen images keeps your site fast and responsive.
2. SEO Boost
Search engines like Google love fast websites. Faster load times can give you a ranking advantage over competitors.
Google's PageSpeed Insights tool even flags when websites are not serving images in next-gen formats, so you know they take this seriously. In the world of SEO, every little edge counts.
3. Reduced Bandwidth Usage
Next-gen formats use less bandwidth because of their smaller file sizes. This can help both website owners (by reducing server costs) and users (by using less mobile data).
If you run a large website or an e-commerce platform with many images, these savings can really add up over time. In tests, AVIF images were shown to be 25-34% smaller in size compared to JPEG images, providing a smoother experience, especially on slower connections
4. High-Quality Images
Despite the reduced file size, next-gen formats still manage to deliver stunning image quality.
You don’t have to compromise on how your images look to achieve a faster website, which is a big win, especially for industries that rely on visuals like photography, retail, and design.

Challenges of Adopting Next-Gen Formats
Of course, no change comes without its challenges. While next-gen image formats offer numerous advantages, there are some obstacles you’ll need to consider.
1. Browser Compatibility
Although next-gen formats like WebP and AVIF are becoming more widely supported, not all browsers support them equally.
For instance, older versions of Safari or Internet Explorer may not render these formats. This means you’ll need to implement fallback images (usually in JPEG or PNG) for users on older browsers, which adds complexity to your workflow.
2. Implementation Complexity
Serving images in next-gen formats often requires updating your website’s image handling process.
If you’re using a content management system (CMS) like WordPress, there are plugins available that can automate the conversion to next-gen formats.
However, if your site is custom-built, you may need a developer to help integrate these formats.
3. File Conversion
Converting your existing images to next-gen formats can take time, especially if you have a large library of images. Fortunately, many tools and services exist that can batch convert your images, but you’ll still need to test the final results to ensure quality.
4. Storage Considerations
While next-gen formats reduce file size, the need for fallback formats can lead to storage challenges.
You’ll essentially be storing two versions of every image (one in next-gen format, the other in an older format like JPEG or PNG). This can increase storage demands on your server.
How to Implement Next-Gen Formats
So, how do you go about implementing next-gen formats for your website? There are a few strategies you can consider:
- Use a Plugin: If you're on a platform like WordPress, plugins like Smush, ShortPixel, or Imagify can automatically convert your images to WebP or AVIF formats. These plugins often provide an easy-to-use interface and handle all the heavy lifting for you.
- Leverage a CDN: Many Content Delivery Networks (CDNs) such as Cloudflare or KeyCDN offer automatic image optimization, converting your images into next-gen formats and serving them based on the visitor’s browser.
- Manually Convert and Serve: If you have a custom website, you may want to manually convert your images using tools like Squoosh, an online image compressor, or command-line tools like ImageMagick. After conversion, you can serve images in both next-gen formats and fallback formats using a picture element in your HTML code.
Conclusion
Next-gen formats are a must if you want to improve your website’s performance and user experience. By serving images in next-gen formats like WebP and AVIF, you can speed up load times, reduce bandwidth, and boost your site’s SEO. Sure, there are some challenges, like browser compatibility and the need for fallback images, but the benefits far outweigh the hurdles
