How It Works

  1. Upload your .avif file using drag and drop or the file browser.
  2. The tool reads the file metadata, including dimensions, bit depth, and color profile.
  3. It detects HDR support, alpha transparency, and animation frames.
  4. A quality score is calculated based on compression efficiency and feature utilization.
  5. Review the recommendations to optimize your image. Need to convert it? Use our AVIF to JPG or AVIF to WebP converters.

Understanding AVIF Features

HDR

High Dynamic Range support enables wider color gamuts and better contrast ratios. AVIF can store HDR content using PQ (Perceptual Quantizer) or HLG (Hybrid Log-Gamma) transfer functions, making it ideal for professional photography and media.

Alpha

Alpha channel support allows transparent backgrounds with excellent compression. This makes AVIF ideal for logos, icons, and UI overlays. If your image needs transparency, you can convert from PNG to AVIF while preserving it.

Animation

AVIF supports animated image sequences with significantly better compression than GIF or WebP. Each frame benefits from AV1 video encoding technology. You can also convert GIFs to animated AVIF for smaller file sizes.

Compression

AVIF typically achieves 20-50% better compression than JPEG at equivalent quality, and 20-30% better than WebP. The compression ratio shown reflects how efficiently your image uses the AV1 encoding versus its uncompressed size.

AVIF Best Practices

Use <picture> Fallbacks

Always include WebP or JPEG fallbacks for browsers without AVIF support. The <picture> element handles this automatically.

Optimize Quality Setting

AVIF achieves great results at lower quality levels. Quality 50-80 typically offers the best size-to-quality balance for web images.

HDR Display Targeting

Use HDR only when targeting HDR-capable displays. SDR images encode faster, display universally, and avoid unexpected color shifts.

Watch Web File Size

Even with great compression, large AVIFs slow pages down. Aim for under 200 KB for web images. Use our AVIF Compressor if needed.

Pro tip: Convert images to AVIF using our PNG to AVIF or JPG to AVIF converters, then run them through this analyzer to verify the results before deploying.

Frequently Asked Questions

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, developed by the Alliance for Open Media. It offers superior compression compared to JPEG and WebP, with support for HDR, wide color gamut, alpha transparency, and animation. You can convert PNG to AVIF or convert JPG to AVIF for free on ConvertICO.

The quality score (0-100) evaluates your AVIF file based on resolution, compression efficiency, and feature utilization. Higher scores indicate better use of AVIF capabilities, including HDR encoding, alpha channels, and optimal compression settings. A score below 60 usually indicates the file could benefit from re-encoding or compression optimization.

AVIF generally provides 20-30% better compression than WebP at equivalent quality. It also supports HDR and handles fine details and gradients more accurately. However, WebP has wider browser support and faster encoding times. For most web projects, AVIF is the better long-term choice, while WebP remains a reliable fallback. You can convert AVIF to WebP for compatibility.

AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, Edge 85+, and Opera 71+. This covers the vast majority of modern browser users. Internet Explorer does not support AVIF. Always provide a fallback format using the <picture> element for older or unsupported browsers.

Yes. AVIF supports animated sequences using the AVIFS container format. Animated AVIF provides significantly better compression than GIF or animated WebP while maintaining high quality. You can convert GIFs to animated AVIF to save bandwidth on your website.

Use the HTML <picture> element to serve AVIF with WebP and JPEG fallbacks: <picture><source srcset="image.avif" type="image/avif"><source srcset="image.webp" type="image/webp"><img src="image.jpg" alt="..."></picture>. First, convert your images using our PNG to AVIF tool, then verify the output with this analyzer.
