PNG to AVIF converter that preserves transparency

PNG is the right choice when you need lossless pixels and/or an alpha channel — logos, UI chrome, screenshots with sharp text, and any graphic where compression artifacts would be obvious. It is a poor default for large photographs because file sizes grow quickly compared with JPG or WEBP.

Export to PNG when editing pipelines expect lossless intermediates, when transparency must be preserved exactly, or when the destination forbids newer formats. For final web delivery of photos, prefer JPG, WEBP, or AVIF instead.

AVIF is an image format based on the AV1 video codec. It typically achieves higher compression efficiency than JPG and often WEBP for the same visual quality, which makes it attractive for bandwidth-sensitive sites and large photo libraries.

Browser support is now broad on current desktop and mobile engines, but encoding is more expensive than JPG. Priconvert encodes AVIF locally with a WASM encoder on first use (cached for the session). Animated AVIF is not supported in this tool.

Both are modern alternatives to JPG/PNG. AVIF usually wins on compression ratio for photographic content; WEBP is faster to encode/decode in many environments and has slightly longer production maturity. WEBP also has a straightforward lossless mode that is a practical PNG replacement for many UI assets.

Prefer AVIF when minimizing bytes matters most and encode time is acceptable. Prefer WEBP when you want a balanced default with broad tooling support. Keep JPG as a compatibility escape hatch when a consumer cannot accept either format.
