Support JPEG XL

[chi]

I think it's a great opportunity for Firefox to stand out by supporting JPEG XL before any other browser.

Imagine images served by Cloudflare and Cloudinary load faster and look better only with Firefox. Firefox was a pioneer of web technologies and it should win the title back, if Firefox just keep following Chrome without any differentiation, why would people choose Firefox?

If the decoder memory safety is a concern, maybe Mozilla can start a crowd funding campaign to sponsor a Rust decoder, even the campaign itself will attract reports and attentions for Firefox.

Mozilla argued AVIF was already supported as a same generation but clearly JPEG XL has many advantages:

• Much better encoding performance (AVIF is not suitable for realtime CDN optimization at all)
• lossless and better high fidelity (video codec based image format)
• HDR (there will be a billion of mobile devices with real good & bright screen in just a few years)
• Little generation loss (important for web)

Supports from Facebook, Adobe (they're adding export support), Intel and VESA, Krita, The Guardian, libvips, Cloudinary, Shopify

Indeed, thanks VcSaJen! Honestly, the timeline is longer than expected, leaves a lot of time for derailment. (And mid-2025 seems so distant and deep into the abyss, esp. due to... politics.) But I'm just happy this is actively being worked on, in good faith, with goals to implement.

JPEG XL is a modern image format designed to replace older formats like JPEG, PNG, and GIF. With its superior compression efficiency and advanced features, it promises to revolutionize how we store and share images. But what exactly is JPEG XL, and why should you care? Let’s break it down.

What is JPEG XL?

JPEG XL is a next-generation image format developed by the Joint Photographic Experts Group (JPEG). It combines the best features of existing formats while addressing their limitations. Key highlights include:

• Better Compression: JPEG XL offers 20-50% smaller file sizes compared to JPEG, without sacrificing quality.

• Lossless and Lossy Compression: It supports both, giving users flexibility depending on their needs.

• Backward Compatibility: JPEG XL can convert older JPEG files without quality loss, making it a seamless upgrade.

Why JPEG XL Matters

1. Superior Image Quality

JPEG XL uses advanced algorithms to preserve image details, even at high compression levels. This means sharper images with smaller file sizes.

2. Faster Loading Times

Smaller files mean faster loading times for websites and apps, improving user experience and SEO rankings.

3. Versatility

JPEG XL supports a wide range of features, including:

• Transparency (like PNG).

• Animation (like GIF).

• High Dynamic Range (HDR) for richer colors and contrast.

4. Eco-Friendly

By reducing file sizes, JPEG XL helps save bandwidth and storage, contributing to a greener digital ecosystem.

Current Support for JPEG XL

While JPEG XL is packed with potential, its adoption is still growing. Here’s where it stands:

• Web Browsers: As of now, Chrome and Firefox have experimented with JPEG XL support, but it’s not yet widely enabled.

• Software: Tools like GIMP and ImageMagick already support JPEG XL, making it easier for creators to use.

• Operating Systems: Support is gradually being added to platforms like Windows and Linux.

---

Challenges Ahead

Despite its advantages, JPEG XL faces some hurdles:

• Adoption Speed: Many platforms and devices still rely on older formats.

• Awareness: Not everyone knows about JPEG XL or its benefits.

• Competition: Formats like WebP and AVIF are also vying for dominance.

FAQs About JPEG XL

1. Is JPEG XL better than JPEG?

Yes, it offers smaller file sizes, better quality, and more features.

2. Can I use JPEG XL on my website?

Yes, but ensure your audience’s browsers support it for optimal results.

3. Is JPEG XL free to use?

Yes, it’s an open standard with no licensing fees.

4. Will JPEG XL replace PNG and GIF?

It has the potential to, thanks to its support for transparency and animation.

5. How do I convert images to JPEG XL?

Use tools like ImageMagick or online converters to get started.

Conclusion

JPEG XL is a game-changing image format that combines efficiency, quality, and versatility. While its adoption is still in progress, its potential to replace older formats is undeniable. For creators, developers, and everyday users, JPEG XL offers a glimpse into the future of digital imaging. As more platforms and tools embrace it, we can expect JPEG XL to become the new standard for images.
