AVIF Compression Quality Settings

The quality setting affects the compression level of the AVIF image:

  • 90-100%: Maximum quality, minimal compression, larger file size with virtually no visual loss
  • 65-85%: Standard quality, good compression, smaller files with barely noticeable quality loss
  • 50-60%: Medium quality, excellent compression, very small files with acceptable quality
  • 30-45%: Low quality, maximum compression, smallest files but visible artifacts may appear

Advantages of AVIF Format

  • Superior compression compared to JPEG, PNG and even WebP formats
  • Better quality-to-size ratio than other common image formats
  • Supports HDR, wide color gamut and high bit-depth images
  • Full alpha channel transparency support (like PNG)
  • Growing support in modern browsers (Chrome, Firefox, Edge, and more)

Important Notes

  • AVIF is a newer format, so compatibility with older browsers is limited
  • For best web compatibility, consider providing JPEG/PNG fallbacks
  • For photography, 75-85% provides an excellent balance of quality and size
  • For illustrations and graphics, 65-75% often provides optimal results

How to Convert and Compress Images to AVIF

Converting your images to AVIF format is simple:

  1. Upload your image files (JPG, PNG, WebP, or GIF) by dragging them to the dropzone or clicking to select.
  2. Adjust the quality slider based on your needs - higher for better quality, lower for smaller file size.
  3. Wait for the conversion and compression to complete.
  4. Download your optimized AVIF images individually or as a ZIP archive.

AVIF offers superior compression compared to other formats, allowing you to reduce file sizes by up to 90% while maintaining excellent visual quality.

FAQ - AVIF Compression

What is AVIF format? +

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It offers superior compression and quality compared to traditional formats like JPEG and PNG, and even outperforms WebP in many cases. AVIF supports high bit depths, HDR, and alpha transparency while maintaining smaller file sizes.

Why convert my images to AVIF? +

AVIF files are significantly smaller than JPEGs and PNGs of similar visual quality - often 30-50% smaller than JPEG and 50-90% smaller than PNG. This means faster website loading times, reduced bandwidth usage, and improved SEO rankings through better page speed scores. AVIF also supports alpha transparency like PNG and offers better quality gradients and color preservation than other formats.

Which browsers support AVIF? +

AVIF is supported in Chrome (version 85+), Firefox (version 86+), and Edge (version 90+). Safari has implemented support in newer versions. For browsers that don't support AVIF, you can use the HTML picture element to provide fallback formats like WebP, JPEG, or PNG. The browser support continues to grow as AVIF becomes more established.

How do I use the quality slider? +

The quality slider lets you control the compression level of your AVIF images. Higher values (75-100%) maintain better visual quality but result in larger files. Lower values (30-60%) produce significantly smaller files but may introduce some visual artifacts. For most purposes, the default 75% setting provides an excellent balance between quality and file size.

What file types can I convert to AVIF? +

Our tool supports converting JPEG, PNG, WebP, and GIF images to AVIF format. All these formats can benefit from AVIF's superior compression, though the most dramatic space savings are typically seen when converting from PNG and JPEG files.

Is there a limit to how many files I can convert? +

Yes, you can convert up to 20 image files at once, with a maximum size of 10MB per file. This limit helps ensure fast processing times and reliable service for all users.

Is my data secure? +

Yes. We don't store your images permanently. They are automatically deleted after 24 hours, and we never access or view your content. The conversion process happens on our secure servers, and your original files are never shared with third parties.

How do I use AVIF images on my website? +

For websites, we recommend using the HTML picture element with fallbacks for browsers that don't support AVIF yet. Here's a basic example:

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

This code will use the AVIF version in supporting browsers, fall back to WebP in browsers that support it but not AVIF, and finally use JPEG in older browsers.
