Convert PNG graphics to AVIF with transparency support. Significantly smaller files. Runs entirely in your browser. No server uploads, no registration required.

PNG is a lossless format that produces large files — ideal for editing but heavy for web delivery. AVIF (AV1 Image File Format) delivers dramatically better compression: files are typically 50–80% smaller than PNG while maintaining excellent visual quality with support for transparency.
AVIF supports millions of colors, full alpha transparency, HDR, and both lossy and lossless modes. It is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Converting PNG to AVIF is one of the most effective ways to optimize website performance.
AVIF uses lossy compression by default — at high quality settings, the difference from the original PNG is imperceptible to the human eye. For pixel-perfect archival copies, keep the original PNG.
All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.
Businesses, developers, and creators worldwide rely on image format compatibility. Whether you are preparing product images for Amazon, eBay, Etsy, Shopify, optimizing graphics for WordPress, Wix, Squarespace, or converting photos for government portals worldwide, having the right format matters.
Modern web standards increasingly favor efficient formats. Google PageSpeed Insights and Core Web Vitals metrics reward pages that use optimized images. Converting PNG to AVIF can directly improve your Largest Contentful Paint (LCP) score, which impacts both search rankings and user experience.
For email marketing campaigns and social media, AVIF provides excellent compression while maintaining visual quality. Whether you are a freelancer, small business owner, or enterprise user, this converter handles your image conversion needs reliably and securely.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.
At 80% quality, AVIF typically reduces PNG file size by 60–80% while maintaining visual quality that is indistinguishable from the original to the human eye.
PNG files are lossless and therefore relatively large. AVIF provides substantial savings:

Actual savings vary depending on image content and quality settings. The converter shows the exact size before and after conversion for each file.
