How to Convert PNG to AVIF Online Securely
Converting a PNG image to AVIF is the absolute best way to optimize transparent graphics and UI elements for the modern web. AVIF supports alpha-channel transparency just like PNG does, but at a fraction of the file size, allowing you to optimize your pages without sacrificing visual detail.
Why convert PNG to AVIF?
PNG is a great lossless format, but its file sizes are often huge, especially for high-resolution graphics. AVIF combines the visual quality of PNG with advanced next-generation compression, preserving transparent alpha channels perfectly while shrinking file sizes by up to 70%. Converting your PNGs to AVIF is a simple step that yields massive page speed gains.
Is this tool safe to use?
Yes. This converter operates 100% inside your browser using client-side JavaScript APIs. Your original PNG and generated AVIF assets never touch our servers, ensuring your visual assets and designs remain completely secure and private.
If you find that your resulting AVIF file is still too large, you might want to try our Compress Image tool to safely reduce its footprint while maintaining visual quality.
