How to Convert WebP to AVIF

  1. Upload your WebP images by dragging and dropping or clicking the upload area. You can convert up to 10 files at once.
  2. Adjust the quality slider - lower values give smaller files, higher values preserve more detail. The 80% default works for most images.
  3. Choose encoding speed: Fast for quick results, Slow for maximum compression. Use Balanced for everyday conversions.
  4. Enable "Preserve transparency" if your WebP has transparent areas - AVIF supports full alpha channel.
  5. Click "Convert to AVIF" and wait for the progress bar to complete.
  6. Download each file individually, or use "Download All (ZIP)" when converting multiple images.

WebP vs AVIF - What Changes?

WebP

Google's modern format offering 25-35% smaller files than JPEG or PNG. Widely supported since 2018. Excellent for web use and already a great choice - but AVIF can improve further. Use our WebP compressor if you want to stay in WebP.

AVIF

Next-generation format based on the AV1 video codec. Typically 20-50% smaller than WebP at similar quality. Supports transparency, HDR, wide color gamut, and lossless mode. The most efficient image format for modern web - use it with our AVIF Analyzer to inspect results.

Quality Settings Guide

90-100%

Near-lossless quality. Best when you plan to edit the image further or need archival fidelity. Ideal when converting from lossless WebP to avoid generation loss.

75-85%

Excellent balance for most web images. Expect 20-40% additional savings over your original WebP with minimal visual difference. Recommended for product photos and hero images.

50-70%

Good compression with noticeable quality trade-off on complex images. Since WebP is already lossy, use with caution. Suitable for thumbnails or very bandwidth-sensitive pages. You can also try our AVIF compressor after conversion for further optimization.

Frequently Asked Questions

AVIF achieves 20-50% smaller file sizes compared to WebP at equivalent visual quality. Smaller images improve Core Web Vitals scores, reduce bandwidth costs, and make pages load faster for visitors. AVIF also supports HDR and wide color gamut - features WebP lacks. If you have many WebP images, batch converting them is an easy performance win.

Since standard WebP is lossy, converting to AVIF involves a second compression step which can add a small amount of quality loss. To minimize this, use 85-95% quality or enable lossless mode. For most web images at 80%+ quality the difference is not visible to the naked eye. Use our AVIF Analyzer to inspect your results.

Yes - AVIF fully supports alpha channel transparency. Enable "Preserve transparency" in the settings and all transparent areas from your WebP will be retained in the AVIF output. AVIF often handles transparency more efficiently than WebP, giving you smaller files without sacrificing the alpha channel.

AVIF is supported in Chrome 85+, Firefox 93+, Edge 121+, Opera 71+, and Safari 16+, covering around 93% of global web users. For the remaining users you can provide a WebP fallback using the HTML <picture> element. If you need to support older browsers fully, our AVIF to WebP converter can help.

Files are stored temporarily only during conversion and deleted automatically within 4 hours. We never keep permanent copies or use your images for any other purpose. We recommend downloading your converted files promptly. Your privacy is important to us - see our privacy policy for full details.

This tool currently handles static WebP images. For animated files, AVIF animation support is still limited in browsers. A better option for animated images is to keep them as WebP or convert to GIF - our GIF tools can help with that workflow.
