Output Dimensions
Leave both blank to keep the original size. If only one value is set, the other side is scaled automatically to preserve aspect ratio.
All processing happens in your browser. Files are never uploaded to any server.
Convert PNG images to AVIF in your browser. AVIF is selected by default; add one or several PNG files, adjust the optional quality or dimensions, and download the converted images.
AVIF uses lossy compression in this converter. Choose Best quality to retain more detail or Smaller file to reduce the size, then compare the result with your PNG. The output is not guaranteed to be smaller for every image.
This AVIF output does not preserve PNG transparency. Keep PNG or use PNG to WebP for artwork that needs a transparent background. Leaving both dimension fields blank keeps the source dimensions; converting cannot restore detail missing from the PNG.
