AVIF vs WebP vs JPEG XL: Which Format to Use?

A comprehensive comparison of next-generation image formats AVIF, WebP, and JPEG XL. Learn which format offers the best compression, quality, and browser support for your website in 2026.

AVIF vs WebP vs JPEG XL: Which Format to Use?

The image format landscape has changed dramatically. JPEG, the format that dominated the web for 30 years, now has three modern challengers — AVIF, WebP, and JPEG XL — each claiming to be the future of web images. But which one should you actually use?

This guide compares all three formats with real-world data, browser support tables, and clear recommendations for different use cases.

Quick Comparison Table

| Feature | AVIF | WebP | JPEG XL | |:---|:---:|:---:|:---:| | Developed by | Alliance for Open Media | Google | JPEG Committee | | Year Released | 2019 | 2010 | 2021 | | Compression | Lossy + Lossless | Lossy + Lossless | Lossy + Lossless | | Transparency | ✅ Yes | ✅ Yes | ✅ Yes | | Animation | ✅ Yes | ✅ Yes | ✅ Yes | | HDR Support | ✅ Yes | ❌ No | ✅ Yes | | Progressive Loading | ❌ No | ❌ No | ✅ Yes | | Lossless JPEG Recompression | ❌ No | ❌ No | ✅ Yes | | Max Dimensions | 8,193×4,320 | 16,383×16,383 | Virtually unlimited | | Encoding Speed | Slow | Fast | Medium | | Decoding Speed | Medium | Fast | Fast |

AVIF — The Compression King

AVIF (AV1 Image File Format) is based on the AV1 video codec developed by the Alliance for Open Media (members include Google, Apple, Microsoft, Netflix, and Meta).

Strengths

  • Best compression ratio — 20–50% smaller than WebP at equivalent visual quality
  • Excellent colour accuracy — Supports wide colour gamut (HDR, 10-bit, 12-bit)
  • Great for photos — Handles photographic content exceptionally well
  • Growing browser support — Chrome, Firefox, Opera, Edge, and Safari (since iOS 16)

Weaknesses

  • Slow encoding — Creating AVIF images takes significantly longer than JPEG or WebP (2–10x slower)
  • Resolution limit — Single tiles are limited to 8,193×4,320 pixels (can be worked around with grid encoding)
  • No progressive decoding — Images load all at once, not gradually
  • Newer format — Some older tools and systems do not support it yet

Best For

High-quality photographs on modern websites where file size is critical (e-commerce product pages, media-heavy sites, photography portfolios).

WebP — The Reliable Standard

WebP was developed by Google and released in 2010. It has had over a decade to mature and now enjoys near-universal browser support.

Strengths

  • Excellent compatibility — Supported by 97%+ of browsers worldwide
  • Fast encoding and decoding — Minimal impact on server and device performance
  • Versatile — Supports lossy, lossless, transparency, and animation
  • Proven and stable — 15+ years of real-world use
  • Broad tool support — Every major image editor, CMS, and CDN supports WebP

Weaknesses

  • Not the best compression — AVIF achieves 20–30% better compression at equal quality
  • No HDR support — Limited to standard 8-bit colour depth
  • No progressive loading — Like AVIF, images load all at once
  • Google dependency — Single-vendor format (though it is open source)

Best For

General-purpose web images where broad compatibility is essential. The safe, default choice for most websites.

JPEG XL — The Future Contender

JPEG XL is developed by the JPEG Committee (the same group behind the original JPEG format). It was designed to be the one format to replace them all.

Strengths

  • Lossless JPEG recompression — Can losslessly convert existing JPEGs to JPEG XL, reducing size by 20–30% without any quality loss at all
  • Progressive decoding — Images load gradually from blurry to sharp (like progressive JPEG, but better)
  • Excellent compression — Competitive with AVIF for lossy and superior for lossless
  • Unlimited resolution — Supports images of virtually any size
  • Rich feature set — HDR, wide gamut, animation, alpha, layers, and more

Weaknesses

  • Browser support is the major problem — Chrome removed support in 2023, Safari supports it but Chrome and Edge do not (as of 2026)
  • Limited tool support — Fewer editors, CDNs, and CMS plugins support it compared to WebP or AVIF
  • Uncertain future — Without Chrome support, widespread adoption is unlikely

Best For

Archival use and workflows where progressive loading is critical. Not recommended as a primary web format until Chrome adds support.

Browser Support Comparison (2026)

| Browser | AVIF | WebP | JPEG XL | |:---|:---:|:---:|:---:| | Chrome | ✅ (v85+) | ✅ (v32+) | ❌ Removed | | Edge | ✅ (v85+) | ✅ (v18+) | ❌ | | Firefox | ✅ (v93+) | ✅ (v65+) | ✅ (v122+) | | Safari | ✅ (iOS 16+) | ✅ (v14+) | ✅ (v17+) | | Opera | ✅ (v71+) | ✅ (v19+) | ❌ | | Samsung Internet | ✅ | ✅ | ❌ |

Global support estimate (2026):

  • WebP: ~97%
  • AVIF: ~93%
  • JPEG XL: ~25% (Safari + Firefox only)

Real-World File Size Comparison

For a typical 2000×1500 pixel photograph:

| Format | Quality Setting | File Size | Visual Quality | |:---|:---:|:---:|:---| | JPEG (original) | 85% | 450 KB | Reference | | WebP | Equivalent | 340 KB (24% smaller) | Identical | | AVIF | Equivalent | 250 KB (44% smaller) | Identical | | JPEG XL | Equivalent | 270 KB (40% smaller) | Identical | | PNG (lossless) | — | 3.2 MB | Perfect | | WebP (lossless) | — | 2.1 MB (34% smaller than PNG) | Perfect | | AVIF (lossless) | — | 1.8 MB (44% smaller than PNG) | Perfect |

Which Format Should You Use? Decision Guide

For Most Websites → WebP

If you want a single format that works everywhere with great compression:

  • 97% browser support — almost no user will have issues
  • 25% smaller than JPEG at equal quality
  • Supports transparency (replaces PNG too)
  • Every CDN, CMS, and build tool supports it

For Performance-Critical Sites → AVIF with WebP Fallback

If you need the absolute smallest files:

  • Use AVIF as the primary format
  • Serve WebP as a fallback for the ~7% of browsers that do not support AVIF
  • Use the HTML <picture> element for automatic format selection
<picture>
  <source srcset="photo.avif" type="image/avif">
  <source srcset="photo.webp" type="image/webp">
  <img src="photo.jpg" alt="Description">
</picture>

For Archival/Photography → JPEG XL

If you want lossless recompression of existing JPEG libraries:

  • JPEG XL can reduce your JPEG archive by 20–30% with zero quality loss
  • But only use it for storage/archival — not for web delivery (no Chrome support)

For Indian Government Portals → JPEG

Government portals strictly require JPEG format. Do not use WebP, AVIF, or PNG:

How to Convert Between Formats

| Conversion | Imgkaro Tool | |:---|:---| | JPG → WebP | Image to WebP | | PNG → JPG | PNG to JPG | | WebP → JPG | WebP to JPG | | WebP → PNG | WebP to PNG | | HEIC → JPG | HEIC to JPG | | SVG → PNG | SVG to PNG |

Frequently Asked Questions

Q: Should I convert all my website images to AVIF? Only if you can serve WebP or JPEG as fallback. Using AVIF alone would break images for ~7% of your visitors.

Q: Will JPEG XL ever get Chrome support? It is uncertain. Google removed the experimental flag in Chrome 110 (2023) and has not shown signs of adding it back. Google actively promotes WebP and AVIF instead.

Q: Is WebP better than JPEG for all images? For photographic content, WebP is 20–30% smaller at equal quality. For simple graphics with few colors, PNG (or WebP lossless) may be more appropriate.

Q: Can I use AVIF for social media? Most social media platforms (Instagram, Facebook, Twitter) automatically convert uploaded images to JPEG or WebP. You can upload AVIF, but the platform will re-encode it.

Q: What format do phone cameras use? iPhones use HEIF/HEIC (can be converted with HEIC to JPG). Android phones typically save as JPEG.
