Convert PNG to AVIF Online
AVIF can shrink a PNG dramatically while keeping transparency, making it ideal for graphics on performance-focused sites. Encoding is slower than other formats, so large images may take a few seconds. Transparency is fully preserved — the alpha channel in your PNG carries over to the AVIF output.

About PNG to AVIF Conversion
This free online converter transforms PNG images into AVIF format directly in your browser. PNG is the lossless format with full transparency, while AVIF is the next-generation AV1-based format. Whether you need broader compatibility, smaller file sizes, or different editing capabilities, switching from PNG to AVIF takes just a few seconds and requires no software installation.
Transparency is fully preserved during this conversion. The alpha channel in your PNG image carries over to the AVIF output intact, so transparent backgrounds stay transparent and no edge detail is lost. The AVIF output uses efficient lossy compression, and a quality slider lets you balance file size against visual fidelity, defaulting to a value that suits the vast majority of images.
This conversion is popular with people who work with logos, screenshots, icons, and graphics with transparent backgrounds, as well as anyone preparing images for performance-focused web delivery where bandwidth matters most. PNG files can be large, especially for photographic content, so moving to AVIF is a sensible, practical step. The result is a clean file that is ready to share, upload, publish, or edit further in your favorite tools.
Your privacy is protected throughout the entire process. Conversion happens entirely inside your browser, so your files never leave your device and are never uploaded to any server. The tool is completely free, handles multiple files at once, and works on any device with a modern browser, making it simple to convert PNG to AVIF whenever you need to.
