WebP to AVIF Conversion 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 Converting WebP to AVIF

  • Superior compression compared to WebP (up to 20% smaller files)
  • Better image quality at equivalent file sizes compared to WebP
  • Supports HDR and wide color gamut images like WebP
  • Full alpha channel transparency support
  • Growing support in modern browsers (Chrome, Firefox, Edge, and more)

FAQ - WebP to AVIF Conversion

What is AVIF format? +

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec. It offers better compression and quality compared to WebP, which was already an improvement over older formats like JPEG and PNG. AVIF supports HDR, wide color gamut, alpha transparency, and high bit depth, making it a complete successor to WebP.

Why convert WebP to AVIF? +

While WebP was already a significant improvement over JPEG and PNG, AVIF takes image compression even further. AVIF files can be up to 20% smaller than equivalent WebP files while maintaining the same visual quality. This means even faster website loading times, reduced bandwidth usage, and improved SEO rankings. If you're already using WebP, upgrading to AVIF is the logical next step for even better performance.

Does AVIF support transparency like WebP? +

Yes, AVIF fully supports alpha channel transparency just like WebP. Our converter preserves all transparency information when converting from WebP to AVIF format. This makes AVIF a complete replacement for WebP with all the same features but better compression.

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. While WebP has wider browser support, AVIF support is growing rapidly. For browsers that don't support AVIF, you can use the HTML picture element to provide WebP as a fallback.

How much better is AVIF compared to WebP? +

In benchmarks, AVIF files are typically 10-20% smaller than WebP files at equivalent quality levels. For some image types, the difference can be even greater. Additionally, AVIF often preserves more detail at the same file size, particularly in areas with complex textures or gradients. The improvement is most noticeable for photographic content but applies to most image types.

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

Yes, you can convert up to 20 WebP 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, WebP in browsers that support it but not AVIF, and fall back to JPG in older browsers.
