Convert images to and from AVIF with quality control.
About the AVIF Converter
Batch-convert PNG, JPG, WebP and GIF images into AVIF for much smaller files, or decode existing AVIF images back to JPG, PNG or WebP. Quality is adjustable, sizes before and after are shown per file, and the tool checks whether your browser supports AVIF encoding before running.
