TRANSPARENCY SUPPORT
Keep transparent backgrounds
AVIF supports alpha transparency. A transparent PNG does not have to stay PNG forever just to keep its background — it can become a smaller AVIF with transparency intact.
MODERN FORMAT
Move to a modern image format
AVIF uses modern image compression and is supported in current browsers and devices. File-size savings vary by image and quality setting, so results are honest rather than a fixed promise.
TRANSPARENCY
Does PNG to AVIF Preserve Transparency?
AVIF supports alpha transparency, so transparent PNG images can remain transparent after conversion when the converter keeps the transparency.
When a file you convert contains transparent pixels, the converter marks it with Transparency preserved next to the result. You don’t need to flatten the image onto a background first.
