Drop your PNG files below to convert them to AVIF. No sign-up, no watermark, batch conversion supported. Files are processed and immediately discarded.
AVIF is the most efficient widely-supported image format available today, often producing files 50% smaller than PNG or JPG at the same visual quality — ideal for reducing bandwidth on image-heavy websites.
AVIF typically compresses smaller than WebP at the same quality, though it can take slightly longer to encode. Both are excellent modern choices; AVIF has slightly less universal older-browser support.
Yes, this converter reads AVIF as an input format too — just choose PNG or JPG as the output format on the main converter.
