What is AVIF?

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It's designed to provide superior compression and image quality compared to older formats like JPEG, PNG, and even WebP.

Key characteristics:

  • File extension: .avif
  • MIME type: image/avif
  • Developed by: Alliance for Open Media (AOMedia)
  • Released: 2019
  • Based on: AV1 video codec

AVIF files can contain both lossy and lossless compressed images, support transparency (alpha channel), HDR (High Dynamic Range), and wide color gamut.

AVIF stands for AV1 Image File Format.

  • AV1: AOMedia Video 1 (the video codec it's based on)
  • Image: Still image format
  • File Format: Container for the image data

It's a royalty-free, open-source image format developed by the Alliance for Open Media (AOMedia), a consortium that includes Google, Mozilla, Netflix, Amazon, and others.

AVIF format is primarily used for:

  1. Web Images: Optimizing website images to reduce bandwidth and improve loading speed
  2. E-commerce: Product photos with high quality at small file sizes
  3. Photography: Storing high-quality photos with better compression than JPEG
  4. Streaming Services: Thumbnails and preview images (Netflix, YouTube)
  5. Mobile Apps: Reducing app size and data usage

Main benefits:

  • 50% smaller file sizes than JPEG
  • Better quality than WebP
  • Supports HDR and wide color gamut
  • Transparency support (like PNG)

Yes, AVIF provides superior compression and quality compared to older formats:

Format File Size Quality Transparency HDR
AVIF 🟢 Smallest 🟢 Excellent ✅ Yes ✅ Yes
WebP 🟡 Small 🟢 Good ✅ Yes ❌ No
JPEG 🟠 Medium 🟡 Good ❌ No ❌ No
PNG 🔴 Large 🟢 Excellent ✅ Yes ❌ No

Real-world comparison: A 2.5 MB JPEG can be compressed to ~1.2 MB as AVIF with the same or better visual quality (52% size reduction).

Browser Support & Compatibility

AVIF is supported by all major modern browsers:

Browser Support Since Status
Google Chrome Version 85+ (August 2020) ✓ Supported
Microsoft Edge Version 85+ (August 2020) ✓ Supported
Firefox Version 93+ (October 2021) ✓ Supported

Current browser support: Over 85% of global internet users can view AVIF images natively.

Growing Support: Browser support for AVIF is rapidly increasing as it becomes the new standard for web images.

Yes! AVIF is ready for production use on websites. Here's how:

Method 1: Picture Element with Fallback (Recommended):

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

This provides AVIF for modern browsers, WebP for mid-range browsers, and JPG as final fallback.

Method 2: Server-Side Content Negotiation:

Configure your server to serve AVIF automatically to browsers that support it.

Benefits for your website:

  • ⚡ 50% faster page loading
  • 📊 Improved Core Web Vitals scores
  • 🚀 Better Google SEO rankings
  • 💰 Reduced bandwidth costs
  • 📱 Better mobile experience

Technical Questions

Yes! AVIF files can contain EXIF metadata, including:

  • 📷 Camera information (make, model, lens)
  • 📍 GPS location data (latitude, longitude, altitude)
  • 📅 Date and time taken
  • ⚙️ Camera settings (ISO, aperture, shutter speed, focal length)
  • ✏️ Author and copyright information

When converting images:

Our converter gives you the option to keep or remove EXIF metadata:

  • ✅ Keep EXIF: Preserves all metadata (useful for photography)
  • 🗑️ Remove EXIF: Strips all metadata for privacy (removes GPS location)

You can view EXIF metadata in AVIF files using our AVIF Viewer.

Yes! AVIF fully supports transparency (alpha channel), just like PNG.

Benefits:

  • ✅ Replace PNG with much smaller AVIF files
  • ✅ Perfect for logos, icons, and graphics with transparency
  • ✅ 50-70% smaller than PNG with same quality
  • ✅ Smooth alpha gradients (better than GIF)

Use case: Convert PNG logos to AVIF to reduce website loading time while keeping transparency.

If images are automatically saving as AVIF when you download them from websites, here's why:

Reason: Many modern websites now serve images in AVIF format to reduce bandwidth and improve loading speed. When you right-click and "Save Image As", you download the AVIF version.

Solutions:

  1. Convert to JPG/PNG: Use our AVIF to JPG converter after downloading
  2. Use browser extension: Install an extension that forces JPG/PNG downloads
  3. Screenshot instead: Take a screenshot and save as PNG (lower quality)

Why websites use AVIF:

  • Faster loading = better user experience
  • Lower bandwidth costs
  • Better SEO rankings (Core Web Vitals)

AVIF supports BOTH lossy and lossless compression:

Lossy AVIF:

  • Smaller file sizes (like JPEG)
  • Some quality loss (usually imperceptible)
  • Best for photos and web images
  • File size: Very small

Lossless AVIF:

  • Perfect quality preservation (like PNG)
  • No quality loss
  • Best for graphics, logos, and when quality is critical
  • File size: Smaller than PNG, larger than lossy AVIF

Our converter: Uses high-quality lossy compression by default (best balance of size and quality). You can choose lossless if needed.

AVIF is generally better than WebP:

Feature AVIF WebP
File Size 🟢 20-30% smaller 🟡 Smaller than JPEG
Quality 🟢 Better at low bitrates 🟡 Good
Browser Support 🟡 85% (growing) 🟢 95% (established)
Encoding Speed 🟡 Slower 🟢 Faster
HDR Support 🟢 Yes 🔴 No
Animation 🟢 Yes 🟢 Yes

Recommendation: Use AVIF for new projects. For maximum compatibility, provide both AVIF and WebP with a fallback to JPG.

Yes! AVIF supports animation through image sequences, similar to animated GIF or WebP.

Benefits of Animated AVIF vs GIF:

  • ✅ 90% smaller file sizes than GIF
  • ✅ Millions of colors (vs GIF's 256 color limit)
  • ✅ Alpha transparency support
  • ✅ Better quality with smooth gradients (no color banding)
  • ✅ Configurable loop: infinite loop, play once, or repeat N times
Important Browser Support Limitation:
Animated AVIF has lower browser support than static AVIF. Chrome and Firefox support it, but Safari does NOT support animated AVIF (only static). Safari will display only the first frame of an animated AVIF.

Browser support for Animated AVIF (2026):

  • ✅ Chrome 85+ (Desktop & Android) - August 2020
  • ✅ Edge 85+ - August 2020
  • ✅ Firefox 93+ - October 2021
  • ✅ Opera 71+ - September 2020
  • ❌ Safari (all versions) - Not supported
  • ❌ Safari iOS - Not supported

Estimated support: ~70-75% of global users (vs 94% for static AVIF)

How to create animated AVIF:

  • Use command-line tools: avifenc, ffmpeg with libavif
  • Convert from video (MP4, MOV), GIF, or image sequences
  • Not commonly available in simple online converters due to encoding complexity
