Why convert WebP to AVIF?

AVIF offers better compression than WebP - often 20-50% smaller file sizes with comparable quality. This means faster page loads, lower bandwidth costs, and better user experience. AVIF also supports wider color gamut and HDR.

Does AVIF support transparency like WebP?

Yes! AVIF fully supports alpha channel transparency, just like WebP. Enable 'Preserve transparency' in the settings to maintain all transparent areas from your WebP files.

What quality setting should I use?

For most web use, 75-85% provides excellent results with significant file size reduction. For photos where quality is critical, use 85-95%. For graphics with sharp edges, consider using 90%+ quality.

WebP vs AVIF Comparison

WebP

Google's modern image format with good compression and transparency support. Widely supported across browsers since 2018. Offers 25-35% smaller files than JPEG/PNG while maintaining quality. Good for web optimization.

AVIF

Next-generation format based on AV1 video codec with superior compression (20-50% smaller than WebP). Supports transparency, HDR, wide color gamut, and both lossy and lossless modes. The most efficient image format for modern web.

Quality Settings Guide

90-100%

Near-lossless quality. Recommended when converting from WebP to avoid generation loss. Best for archival or when the image will undergo further editing.

75-85%

Excellent balance of quality and file size. Recommended for most web use. You may achieve 20-40% additional savings over WebP with minimal visual difference.

50-70%

Good compression with some visible quality reduction. Since WebP is already compressed, use with caution. Suitable for thumbnails or bandwidth-constrained situations.

Frequently Asked Questions

AVIF offers even better compression than WebP - typically 20-50% smaller file sizes with comparable visual quality. This results in faster page loads, reduced bandwidth costs, and improved Core Web Vitals scores. AVIF also supports wider color gamut and HDR content, making it the most advanced image format available today.

Since WebP is already a lossy format (unless lossless WebP), converting to another lossy format can introduce some generation loss. To minimize this, use a higher quality setting (85-95%) or enable lossless mode. For most web use cases, 80-85% quality provides excellent results with minimal perceptible difference.

Yes! AVIF fully supports alpha channel transparency, just like WebP. When you enable "Preserve transparency" in the settings, all transparent areas in your WebP will be maintained in the converted AVIF file. AVIF actually handles transparency more efficiently than WebP in many cases.

AVIF is supported in Chrome 85+, Firefox 93+, Edge 121+, Opera 71+, and Safari 16+. This covers approximately 93% of global web users as of 2024. For older browsers, consider providing WebP or JPEG fallbacks using the HTML <picture> element for progressive enhancement.
