PNG vs AVIF — Size Comparison with Transparency
The file size difference between PNG and AVIF is dramatic, especially for images with transparency.
| Asset Type | Typical PNG Size | AVIF Size | Reduction |
|---|---|---|---|
| Logo with transparency | 80 KB | 8-15 KB | 81-90% |
| UI icon set (100 icons) | 5 MB total | 500 KB total | ~90% |
| Product photo (background removed) | 800 KB | 80-120 KB | 85-90% |
| Infographic with transparency | 1.2 MB | 150-250 KB | 79-88% |
| Screenshot (opaque) | 400 KB | 60-100 KB | 75-85% |
| Banner graphic | 300 KB | 30-60 KB | 80-90% |
PNG to AVIF conversion is most impactful for transparent images and graphics. The size reduction is dramatic enough to significantly improve page load times, especially on image-heavy pages.
Why Convert PNG to AVIF?
PNG files with transparency are essential for web design — logos, icons, UI elements, and product images with removed backgrounds all require alpha channel support. The problem is that PNG files are large because they use lossless compression. A single PNG icon can be 50-200 KB, and a product image with transparency can easily exceed 1 MB.
AVIF solves this by supporting transparency while using highly efficient lossy or lossless compression. A PNG file that's 500 KB typically compresses to 50-100 KB as AVIF — an 80-90% reduction — with no visible quality difference in the transparent or opaque areas.
For web developers, this means faster page loads, better Core Web Vitals scores, and lower CDN bandwidth costs. For e-commerce sites with hundreds or thousands of product images with removed backgrounds, the bandwidth savings are enormous.
Unlike JPG, which cannot store transparency, AVIF preserves your alpha channel perfectly. This makes AVIF the ideal replacement for PNG on the web — you get the transparency you need with dramatically smaller file sizes.
