AVIF Compressor

Compress AVIF images to reduce file size while maintaining excellent visual quality. AVIF offers superior compression compared to JPEG and WebP, making it ideal for web optimization. Use our AVIF Analyzer to inspect your images first.

How to Compress AVIF Images

  1. Upload your AVIF images by dragging and dropping or clicking the upload area. You can select up to 10 files at once for batch compression.
  2. Choose compression settings: Select lossy (smaller files) or lossless (perfect quality). Adjust the quality slider and encoding speed based on your needs.
  3. Optional resizing: Enable resize options to reduce dimensions along with file size. Use percentage or exact dimensions.
  4. Compress and download: Click compress and download individual files or all as a ZIP archive.
Pro tip: Use our AVIF Analyzer to check your image properties before compressing, or convert from PNG or JPG for optimal results.

Why Use AVIF Format?

Superior Compression

Up to 50% smaller than JPEG at the same visual quality. Better than WebP for most images.

HDR & Wide Color

Supports 10-bit and 12-bit color depth, plus HDR content. Perfect for professional photography.

Transparency Support

Full alpha channel support like PNG, combined with excellent compression.

Growing Browser Support

Supported by Chrome, Firefox, Opera, Edge, and Safari 16+. Over 90% global coverage.

Quality Settings Guide

80-100%

High quality: Visually indistinguishable from original. Best for photography, portfolio images, and situations where quality is paramount. Smaller savings but excellent results.

60-79%

Balanced: Excellent quality with significant file size reduction. Recommended for most web images, blog posts, and general use. The sweet spot for most users.

40-59%

Good compression: Noticeable artifacts on close inspection but still good for thumbnails, previews, and bandwidth-conscious applications.

Below 40%

Maximum compression: Visible quality loss. Use only when file size is critical and quality is secondary. Consider using our Image Resizer to reduce dimensions instead.

AVIF vs Other Formats

AVIF

Next-generation format with the best compression ratio. Supports lossy/lossless, transparency, HDR, and animation. Encoding can be slower but results in significantly smaller files.

WebP

Google's format with good compression. Faster encoding than AVIF but larger files. Consider using our WebP Compressor for legacy browser support.

JPEG

Universal format with 100% browser support. Use our JPG Compressor when maximum compatibility is needed, though file sizes will be larger.

PNG

Best for graphics with transparency and sharp edges. Larger files than AVIF. See our PNG Compressor for lossless optimization.

Frequently Asked Questions

AVIF (AV1 Image File Format) compression reduces the file size of images using the AV1 video codec's intra-frame compression. It can be lossy (discarding some data for smaller files) or lossless (preserving every pixel). AVIF typically achieves 50% smaller files than JPEG at equivalent quality, making it ideal for web optimization.

For most web images, 60-75% quality offers excellent results with significant file size reduction. For photography and high-quality visuals, use 80-90%. Below 50% introduces visible artifacts. Start with 65% (our default) and adjust based on your specific needs and visual inspection.

The encoding speed controls how much time the encoder spends optimizing the image. "Fast" produces results quickly but with larger files. "Best Quality" takes longer but achieves smaller file sizes at the same quality level. "Balanced" is recommended for most users as it provides good compression without excessive wait times.

Use lossless mode for graphics with text, logos, screenshots, diagrams, or any image where you need pixel-perfect preservation. For photographs and complex images, lossy compression at 80-90% is usually indistinguishable from lossless while being significantly smaller.

Yes! AVIF fully supports transparency (alpha channel) in both lossy and lossless modes. This makes it an excellent replacement for PNG when you need both transparency and small file sizes. Convert your transparent PNGs using our PNG to AVIF converter.

AVIF is supported by Chrome 85+, Firefox 93+, Opera 71+, Edge 121+, and Safari 16+. As of 2024, this covers over 90% of global users. For broader compatibility, use the HTML picture element with JPEG or WebP fallbacks.

Each file can be up to 20MB, and you can upload up to 10 files at once for batch compression. For very large images, consider using the resize option to reduce dimensions, which also significantly reduces file size.
