When Should You Convert PNG to AVIF?
Cutting-edge web projects
You're building for modern browsers and want the smallest possible transparent images. AVIF with alpha channels beats WebP and PNG for size on virtually every image. If your audience is on current browsers, there's no reason not to use it.
Large graphic archives
Storing thousands of PNG files for a design team, stock library, or content pipeline? Converting to AVIF can reclaim enormous amounts of storage. We're talking 50-70% reduction on many graphics while keeping lossless quality intact.
Detailed web graphics
Charts, infographics, data visualizations, and complex illustrations with lots of color and fine detail benefit hugely from AVIF's compression. These images are often heavy as PNG — AVIF makes them manageable without sacrificing any visible detail.
Progressive enhancement strategy
Serve AVIF to the ~93% of browsers that support it and fall back to PNG for the rest. You get the performance benefit for the vast majority of your traffic while maintaining compatibility for everyone.
