Technical Details
AV1 Codec Technology
AVIF utilizes the AV1 video codec for still images, providing superior compression efficiency through advanced intra-frame prediction, transform coding, and entropy coding techniques that significantly outperform PNG’s DEFLATE algorithm.
Color Space Enhancement
While PNG is limited to sRGB color space with 8-bit channels, AVIF supports Rec. 2020, P3, and sRGB color spaces with 8, 10, or 12-bit precision, enabling better color reproduction and HDR content support.
Alpha Channel Preservation
AVIF maintains PNG’s transparency capabilities through alpha channel support while adding film grain synthesis and improved chroma subsampling options for better transparency edge quality and smaller file sizes.

Frequently Asked Questions
How much smaller are AVIF files compared to PNG?
AVIF files are typically 50-90% smaller than equivalent PNG files while maintaining the same visual quality. The exact reduction depends on image content, with photographs showing the greatest compression improvements.
Will converting PNG to AVIF reduce image quality?
AVIF supports both lossless and lossy compression modes. When using appropriate quality settings, AVIF can maintain visually identical quality to PNG while achieving significant file size reductions through superior compression algorithms.
Does AVIF support transparency like PNG?
Yes, AVIF fully supports alpha channel transparency just like PNG. The transparency information is preserved during conversion, often with better compression efficiency than PNG’s transparency handling.
Which browsers support AVIF images?
AVIF is supported by Chrome 85+, Firefox 93+, and Safari 16+. While browser support is growing rapidly, consider providing PNG fallbacks for older browsers in web applications.
Can I convert large PNG files to AVIF?
Yes, Convertify can handle PNG files of any size without limitations. Large PNG files often see the most dramatic size reductions when converted to AVIF, making it ideal for high-resolution images and artwork.
Is PNG to AVIF conversion reversible?
Converting AVIF back to PNG is possible, but if lossy AVIF compression was used, some quality loss may occur. For archival purposes, consider keeping original PNG files or using lossless AVIF compression.
How does AVIF color depth compare to PNG?
PNG supports 8-bit color depth, while AVIF supports 8, 10, and 12-bit color depths with HDR capabilities. This means AVIF can represent more colors and better gradients than PNG format.
Can I batch convert multiple PNG files to AVIF?
Yes, Convertify supports batch processing to convert multiple PNG files to AVIF simultaneously. This feature is available in the Basic and Pro tiers for efficient bulk conversion workflows.
