Convert PNG to AVIF — Tiny Files, Full Transparency
PNG files are lossless and often very large, especially for photographs or complex graphics. AVIF compresses them to a fraction of the size while preserving transparency — making it one of the most impactful conversions for web performance. A 2 MB PNG can easily become a 100 KB AVIF with no visible quality loss.

Why Convert PNG to AVIF?
Unlike JPG, AVIF supports transparency just like PNG, so you get the best of both worlds: tiny file sizes and alpha channel support. This makes AVIF the ideal replacement for PNG on the web. Icons, logos, UI elements, and product photos with transparent backgrounds all benefit enormously from the switch.

Quality Note
PNG-to-AVIF is a lossless-to-lossy conversion. At quality 80+, the visual difference is imperceptible and file size reduction is dramatic — often 90% or more. For pixel-perfect reproduction, AVIF also supports a lossless mode, though file sizes will be larger.
