PNG to AVIF Online Converter
AVIF provides much smaller file sizes compared to PNG while maintaining excellent visual quality. Ideal for web graphics and user interfaces.
What happens when you convert PNG to AVIF
This page prepares PNG files for AVIF output. The converter decodes the source image, redraws it on a clean canvas and exports a new file in the selected format. This is useful when you need a file that opens in more apps, loads faster on a website, or fits a specific publishing workflow.
Conversion workflow
- Upload one or several PNG files with the form above.
- The browser reads the image data and checks that the file type is supported.
- FormatKit creates a new AVIF file and keeps the original file unchanged.
- Download the result immediately after processing.
