AVIF Frequently Asked Questions

Which browsers support AVIF?
AVIF works in Chrome 85+, Firefox 93+, Safari 16+ (iOS 16 and macOS Ventura), and Edge 121+. This covers approximately 85% of web users in 2026.

For maximum compatibility, use the HTML picture tag with a WebP or JPG fallback: 
<picture>
  <source srcset="image.avif" type="image/avif">
  <source srcset="image.webp" type="image/webp">
  <img src="image.jpg" alt="description">
</picture>
Many CMSs like WordPress 6.5+ handle this automatically.
What's the difference between AVIF and WebP?
AVIF offers better compression (20-30% more efficient than WebP) and supports advanced features like HDR and greater color depth, ideal for high-quality photography. WebP has better compatibility (98% vs 95%) and faster decoding. 2026 Recommendation: use AVIF for premium projects where visual quality is critical; use WebP for universal compatibility and general performance.
What type of images is AVIF best for?
AVIF is ideal for high-quality photographs, hero images, main banners, photography portfolios, product galleries and any visual content where quality is a priority. It excels with smooth gradients, complex textures, and fine details. Supports transparency (like PNG) with files up to 50% lighter. Perfect for premium websites seeking the best balance between visual quality and load speed.
Does AVIF support transparency like PNG?
Yes, AVIF supports full alpha channel (transparency) with superior compression to PNG or WebP. You can use AVIF for logos, icons, and graphics with transparent backgrounds, getting files up to 50-60% lighter than PNG with the same visual quality. It's technically the best option for images with transparency in 2026.
How much can I reduce the size of an AVIF image?
With our additional optimization, you can reduce between 10% and 25% the size of already compressed AVIF files. Best results are obtained with AVIF images exported from graphic editors (Photoshop, GIMP, Figma) that include heavy metadata. If converting from JPG or PNG to optimized AVIF, you can achieve reductions of up to 40-60% compared to the original file without noticeable visual loss.
AVIF or JPG for photographs on my website?
AVIF is technically superior for photographs: it offers 30-50% better compression than JPG with the same perceived quality, supports HDR and greater color richness. However, JPG has universal compatibility (100%). Recommended strategy: use AVIF with JPG as fallback in your HTML code, or use AVIF directly if your analytics shows your audience uses modern browsers (2020+).
Are there disadvantages to AVIF?
The main one: encoding time. AVIF takes 3-5x longer to process than WebP due to the complexity of the AV1 codec. This does not affect viewing speed (it loads just as fast), only the initial export time.
It also requires modern browsers. If your audience uses older devices (pre-2022 iPhone, pre-2021 Android), consider using WebP or JPG as the primary format with AVIF as a progressive enhancement.

How AVIF Compression Works?

AVIF uses the AV1 codec, the same one Netflix uses for efficient 4K video. It is up to 50% more efficient than WebP and 80% better than JPG. However, exports with maximum quality save redundant information that can be optimized.

Our tool analyzes the file and adjusts compression parameters without affecting what you see. We reduce unnecessary color matrices, remove EXIF metadata, and re-encode with optimized settings. Result: 15-30% less weight while maintaining full HDR and color depth.
