The conversion method
The tool loads your PNG into a canvas, optionally scales it, and encodes it as AVIF using the browser's native image encoding support. The quality setting controls the compression level — higher quality means larger files but better visual fidelity.
FAQ
What is AVIF?
AVIF (AV1 Image File Format) is a modern image format that offers better compression than PNG and JPEG, resulting in smaller file sizes at similar quality.
Why convert PNG to AVIF?
AVIF files are typically 50% smaller than PNG files at similar visual quality, making them ideal for web use where file size matters for page load speed.
Is my image uploaded anywhere?
No — the conversion happens entirely in your browser using the Canvas API. Your image never leaves your device.
