The Future of Image Formats: Beyond AVIF and GIF

The landscape of image formats is constantly evolving. While AVIF represents the current cutting edge and GIF remains a classic standard, new formats and technologies are already on the horizon. This article explores what's coming next in the world of digital images and what it means for web developers, content creators, and users.

The Evolution of Image Formats

To understand where we're going, it helps to look at where we've been. Image formats have evolved significantly over the decades:

  • 1987: GIF introduced, bringing simple animations to the web
  • 1992: JPEG standardized, revolutionizing photo compression
  • 1996: PNG developed as a lossless alternative to GIF
  • 2010: WebP introduced by Google, improving on both JPEG and PNG
  • 2019: AVIF released, offering significant improvements in compression and quality

Each new format has addressed limitations of previous formats, typically offering better compression, quality, or features. This evolution continues today with several promising new formats in development.

Emerging Image Formats

JPEG XL

JPEG XL (JXL) is designed as a universal image format to eventually replace both JPEG and PNG:

  • Compression: 60% smaller files than JPEG with better quality
  • Features: Supports animation, alpha transparency, HDR, wide color gamut
  • Lossless JPEG transcoding: Can losslessly convert existing JPEGs with 20% size reduction
  • Progressive decoding: Images appear quickly and refine as more data loads
  • Current status: Specification finalized, browser support growing but still limited

JPEG XL is particularly promising because it's designed by the JPEG committee itself as a true successor to the original JPEG format, with significant input from industry experts.

WebP2

Google is working on WebP2, the next generation of the WebP format:

  • Goals: 30% better compression than WebP while maintaining quality
  • Features: Improved HDR support, better animation capabilities
  • Technology: Based on lessons learned from both WebP and AVIF
  • Current status: In development, with experimental builds available

Given Google's influence on web standards and Chrome's market share, WebP2 could see rapid adoption once finalized.

HEIF (High Efficiency Image Format)

While HEIF has been around for a few years (it's what Apple uses for photos on iOS), its adoption continues to expand:

  • Compression: Similar efficiency to AVIF
  • Features: Support for image collections, derived images, and auxiliary images
  • Ecosystem: Strong support in Apple ecosystem, growing elsewhere
  • Limitations: Patent licensing concerns have limited web adoption

Beyond Traditional Image Formats

Vector-Based Approaches

While raster formats like JPEG and AVIF will continue to dominate for photographs, vector-based approaches are evolving:

  • SVG improvements: The SVG 2 specification adds new features and capabilities
  • Vector-raster hybrids: Formats that combine vector elements with raster techniques
  • AI-based vectorization: Converting raster images to vectors with increasing accuracy

Neural Network-Based Compression

Some of the most exciting developments involve using neural networks for image compression:

  • Learned Image Compression: Using AI to achieve better compression than traditional algorithms
  • Content-Aware Compression: Adapting compression based on image content
  • Super-Resolution: Transmitting low-resolution images and using AI to upscale them client-side

These approaches could eventually lead to entirely new image format paradigms that are fundamentally different from traditional pixel-based formats.

The Future of Animation Formats

While GIF has shown remarkable staying power for animations, its future is increasingly challenged:

Animated WebP and AVIF

Both WebP and AVIF support animation with significantly better compression than GIF:

  • Smaller file sizes (often 10-20x smaller)
  • Better color reproduction
  • Support for alpha transparency

Video Formats for Short Animations

For many use cases traditionally served by GIF, short video clips are becoming more common:

  • MP4 (H.264) videos are often 10x smaller than GIFs
  • AV1 video offers even better compression
  • HTML5 video elements provide better control over playback

Interactive and Programmable Animations

Beyond traditional frame-based animations, we're seeing growth in:

  • Lottie animations (JSON-based, vector animations)
  • CSS animations for simple motion
  • WebGL for complex, interactive graphics

Implications for Web Development

Format Detection and Fallbacks

As new formats emerge, developers need robust strategies for format detection and fallbacks:

<picture> <source srcset="image.jxl" type="image/jxl"> <source srcset="image.avif" type="image/avif"> <source srcset="image.webp" type="image/webp"> <img src="image.jpg" alt="Description"> </picture>

This approach will likely need to expand to include more formats in the future.

Conversion Tools and Services

As the format landscape becomes more complex, conversion tools become increasingly important:

  • Browser-based converters (like our AVIF to GIF converter)
  • Server-side conversion services
  • Content Delivery Networks (CDNs) with on-the-fly format conversion

Performance Budgeting

With more efficient formats, performance budgets can be reconsidered:

  • Higher quality images within the same budget
  • More images without impacting page load times
  • Better user experiences on limited bandwidth connections

Challenges and Considerations

Browser and Software Support

New formats face the chicken-and-egg problem of adoption:

  • Browsers are hesitant to add support until formats are widely used
  • Content creators are hesitant to use formats until browser support is strong
  • Software tools lag behind in supporting new formats

Patent and Licensing Issues

Intellectual property concerns continue to impact format adoption:

  • Royalty-free formats tend to see faster web adoption
  • Patent encumbered formats often face resistance in open-source software
  • Licensing complexity can slow industry adoption

Backward Compatibility

The web's need for backward compatibility means older formats will persist:

  • GIF will likely remain supported for decades to come
  • JPEG and PNG will continue to be universal fallbacks
  • New formats need to provide compelling advantages to overcome inertia

Preparing for the Future

For developers and content creators, several strategies can help prepare for the evolving landscape:

Format-Agnostic Workflows

Design workflows that aren't tied to specific formats:

  • Store master images in high-quality, lossless formats
  • Generate delivery formats as needed
  • Use automation to create multiple format variants

Progressive Enhancement

Embrace progressive enhancement for images:

  • Provide basic experiences that work everywhere
  • Enhance for browsers that support newer formats
  • Use feature detection rather than browser detection

Stay Informed

Keep up with developments in image format technology:

  • Follow browser release notes for new format support
  • Test emerging formats in development environments
  • Participate in standards discussions when possible

Conclusion

The future of image formats is exciting and dynamic. While AVIF represents the current state-of-the-art and GIF continues to serve as a universal fallback for animations, formats like JPEG XL and WebP2 promise even better performance and capabilities.

Beyond traditional formats, AI-driven approaches and hybrid techniques may eventually transform how we think about images on the web entirely. For now, a pragmatic approach that leverages the best of current formats while preparing for future developments is the wisest strategy.

As these new formats emerge, conversion tools like our AVIF to GIF converter will continue to play an important role in bridging the gap between cutting-edge performance and universal compatibility.
