Why encode PNG as AVIF
PNG is a reliable lossless original, but it is often too large to ship on a website. AVIF typically produces a much smaller file for photographs and many illustrations, which is why it appears in modern image CDNs.
Use PNG as the working original and AVIF as the delivery copy. If a destination still cannot open AVIF, keep a JPG or WebP fallback rather than replacing the PNG source.
Frequently asked questions
Does AVIF keep PNG transparency?
Yes. AVIF can store an alpha channel, so transparent areas remain transparent.
Why is the first conversion slower?
Browsers cannot encode AVIF with the built-in canvas encoder used for JPG and WebP. Labmorf loads a WASM encoder only when you start converting.
Is AVIF always smaller than PNG?
Usually for photographs. Tiny, already-optimized PNG icons may not shrink much, and very high quality settings trade size for fidelity.
