Why convert AVIF to PNG
AVIF is the newest of the web image formats and the one your desktop software is least likely to open. Converting to PNG is the right choice when the image has a transparent background — a logo or a cut-out — because JPG would fill that transparency with white. It is also the better destination when you intend to edit the image, since PNG is lossless and repeated saves will not degrade it further.
What this conversion costs you
- The file grows, often several times over. AVIF is dramatically more efficient than PNG. A 200 KB AVIF can easily become a 2 MB PNG carrying the same picture.
- Wider colour and HDR are flattened. AVIF can describe a wider range of colour and brightness than a standard PNG. Very saturated or very bright areas may look slightly duller on a display capable of showing the original range.
When not to do this
If the image is a photograph with no transparency and you are not going to edit it, convert to JPG instead — the file will be a fraction of the size for no visible difference.
Common questions
Does AVIF to PNG keep transparency?
Yes. Both formats support an alpha channel, so transparent areas stay transparent. That is the main reason to pick PNG over JPG for this conversion.
Why is the PNG so much larger than the AVIF?
AVIF uses modern lossy compression while PNG is lossless and cannot approximate anything. A file several times larger is normal and expected.
Does this conversion lose quality?
Nothing further is lost in the picture itself, because PNG stores the decoded image exactly. Any compression AVIF already applied remains baked in.
