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.
Convert PNG to AVIF for web graphics, logos, UI elements, and illustrations where you need excellent quality with much smaller files. AVIF supports transparency (alpha channel), so it is a direct replacement for transparent PNGs in modern browsers.
AVIF's support for transparency is key: unlike JPG, AVIF handles alpha channels the same way PNG does. On Chrome and Safari, you can replace transparent PNGs with AVIF files and see dramatically reduced payload with no visible quality difference.
Drag your PNG file into ImgSwift or click to select. Transparent PNGs are fully supported.
Choose AVIF. For web delivery, quality 80–90 gives near-lossless results at a fraction of PNG file size.
Save and deploy the AVIF file. Transparency is preserved.
Yes. AVIF supports full alpha channel transparency, making it a direct replacement for transparent PNGs in browsers that support AVIF.
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 usually 3–5x smaller.
AVIF supports both lossy and lossless modes. Most converters (including ImgSwift) use lossy by default for smaller sizes, but lossless AVIF is available and still significantly smaller than PNG.
