⚠️ AVIF encoding requires Chrome 85+, Firefox 93+, or Safari 16+. ImgSwift automatically shows AVIF options when your browser supports them.

Why Convert PNG to AVIF?

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.

How to Convert PNG to AVIF — 3 Simple Steps

  1. 1
    Upload your PNG image

    Drag your PNG file into ImgSwift or click to select. Transparent PNGs are fully supported.

  2. 2
    Select AVIF output format

    Choose AVIF. For web delivery, quality 80–90 gives near-lossless results at a fraction of PNG file size.

  3. 3
    Download your AVIF image

    Save and deploy the AVIF file. Transparency is preserved.

Frequently Asked Questions

Does AVIF support transparency like PNG?

Yes. AVIF supports full alpha channel transparency, making it a direct replacement for transparent PNGs in browsers that support AVIF.

How much smaller is AVIF vs PNG?

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.

Is AVIF lossless?

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.

Can I use AVIF for website icons and logos?

Yes, for modern browsers. Use a element with AVIF as the primary source and PNG as the fallback for full cross-browser support.
