PNG to AVIF converter
Free PNG to AVIF converter: encode PNG assets as modern AVIF directly in your browser. Best results in current Chromium-based browsers like Chrome or Edge.
Overview
AVIF can produce very small files for the same dimensions. This tool draws your PNG to a canvas and requests `image/avif`. If export is unsupported, try Chrome or Edge current versions. For AVIF → PNG, use the AVIF to PNG tool.
Conversion pair
Provide one .PNG asset and download .AVIF encoded entirely in-browser—pixels stay on your machine throughout the swap.

Frequently asked questions
Why does PNG to AVIF conversion or export fail?
AVIF encoding from canvas is not universal. Safari and some browsers may lack encoders even if they can decode AVIF.
Does PNG to AVIF keep transparency?
When encoding succeeds, alpha is typically preserved; verify in your target pipeline.
Is PNG to AVIF conversion private? Do you store my file?
No. Files never leave your device through this page.
