Convert PNG to AVIF online free. Dramatically reduce image file size while keeping sharp details. Next-gen compression for modern web. No upload.
PNG files are large by nature — they use lossless compression, which preserves every pixel but results in big file sizes. AVIF offers a smarter alternative: lossy AVIF at quality 90 is often visually identical to PNG but 5–10x smaller, making it ideal for web delivery.
Drop your PNG file into IMGVO. Transparent PNGs are fully supported — alpha channel preserved.
For web delivery, quality 75–85 gives visually identical results to PNG at a fraction of the size.
Use the AVIF in your website. Always include a PNG fallback for maximum compatibility.

Yes. AVIF supports full alpha channel transparency, making it a direct replacement for transparent PNGs in browsers that support it.
It depends on the image, but AVIF at quality 85 is typically 5–10x smaller than a lossless PNG. Even at quality 95, AVIF is dramatically smaller while remaining visually identical.
AVIF supports both lossy and lossless modes. Most converters (including IMGVO) use lossy by default for smaller sizes, but lossless AVIF is available for archival use.
Yes, for modern browsers. Use a <picture> element with AVIF as the primary source and PNG as the fallback for full cross-browser compatibility.
