Why convert AVIF to PNG?
AVIF can store efficient web images, while PNG is accepted by many editors and graphics workflows. A PNG made from an AVIF can be much larger because PNG does not use the same compression.
PNG keeps transparency and the dimensions of the decoded AVIF. The output is created from pixels, so AVIF metadata and animation are not copied.
Browser decoding varies
Input support depends on whether the browser can decode that AVIF variant. The tool uses the native browser decoder and displays an error if the image cannot be opened.
The converter does not fetch remote resources or send your file to a server. Very large files still use memory on the device, so smaller batches may work better on phones.
