Compress AVIF Online Free: Reduce File Size Without Losing Quality

Optimize your AVIF files and reduce their size by up to an additional 30% without sacrificing photo quality. Although AVIF is already the most efficient format (surpassing WebP by 20-30%). Our intelligent compressor removes excess data and optimizes compression while maintaining visual quality, HDR support, and 10-bit color. Perfect for high-resolution photographs, hero images, and web portfolios.

What Can You Use AVIF Optimization For?

AVIF is the most advanced format for web images. Optimizing it further has specific benefits depending on use.

Premium Photography

Maintains HDR and 10-12 bit depth with files up to 50% lighter than WebP. Ideal for portfolios and galleries.

Hero Banners & Main Images

Hero images that load instantly, improving LCP and the first impression of your website.

Photography Portfolios

Present your work with professional quality without sacrificing load speed. Smooth gradients and fine details preserved.

Product Galleries

Display products with true colors and sharp textures in ultra-light files. Perfect for premium e-commerce.

FAQ

AVIF Frequently Asked Questions

01 Which browsers support AVIF? +
AVIF works in Chrome 85+, Firefox 93+, Safari 16+ (iOS 16 and macOS Ventura onwards), and Edge 121+, covering more than 90% of users. It can still fail in legacy browsers and unrecognized software, like certain image editors or upload platforms.

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>
WordPress 6.5+ supports uploading and displaying AVIF, but serving automatic fallbacks usually requires a plugin or an image CDN.
02 How much better is AVIF than WebP and JPG? +
At similar visual quality, AVIF typically weighs around 20% less than WebP and between 30% and 50% less than JPG. It also supports HDR, higher color depth (10 and 12-bit), and wide color gamuts. In return, encoding takes longer, decoding is slightly slower, and it has lower compatibility than WebP. A common strategy is serving AVIF with WebP and JPG fallbacks using the picture tag.
03 What type of images is AVIF best for? +
AVIF performs best with photographs, hero images, banners, and product galleries, especially those with smooth gradients, skies, and uniform color areas, where it significantly reduces color banding compared to JPG. Note that at lower quality settings, it tends to smooth out fine textures and film grain, so for highly detailed images it's best to increase quality and compare against the original.
04 Does AVIF support transparency like PNG? +
Yes, AVIF supports full alpha channel transparency. In lossy mode, it can be much smaller than a PNG at the expense of slight detail. In lossless mode, it doesn't always win: lossless WebP or a well-optimized PNG can result in similar or smaller file sizes. For logos and icons with sharp edges and flat colors, SVG is usually the ideal choice.
05 Are there disadvantages to AVIF? +
The main one is encoding time: it is often several times slower than WebP due to the complexity of the AV1 codec, although this only affects export time. Other limitations: slightly slower decoding on low-end devices and less software and platform support. If your audience uses older devices, use AVIF as a progressive enhancement, always with WebP or JPG fallbacks.
Notes

How Does AVIF Compression Work?

AVIF (AV1 Image File Format) is an image format based on the AV1 video codec, the same standard used by streaming services like Netflix and YouTube. Each image is encoded as an AV1 keyframe inside a HEIF container. At similar visual quality, it typically weighs around 20% less than WebP and between 30% and 50% less than JPG.

The codec divides the image into flexible-sized blocks (up to 128x128 pixels), predicts each block from neighboring pixels, and quantizes the difference, which is where data is discarded. It then applies filters like deblocking and CDEF to eliminate artifacts. AVIF supports 8, 10, and 12 bits per channel, HDR, wide color gamuts, alpha transparency, and a lossless mode. Its trade-off is much slower encoding than JPG or WebP.

OptimizeImg re-encodes AVIF files with a more precise quality target and strips unnecessary metadata. Depending on the file, typical savings range between 10% and 25%, and are lower on already optimized images.
