What the PNG holds on to

Transparency survives exactly, soft edges included, and nothing is painted underneath the picture.
Nothing further is compressed away, though whatever the AVIF already lost stays lost.
The file gets very large. AVIF is among the most efficient formats and PNG among the least, and PNG is sized by the pixel count rather than by what the AVIF weighed.

How lossless this actually is

"Lossless" is doing two different jobs in the sentence above, and only one of them is a guarantee. Worth separating them before you rely on either.

The guarantee is forward-looking, and it is real. From the moment this PNG is written, every save is exact: open it, paint on it, save, reopen, save again, and the twentieth version is bit-for-bit the pixels of the first. That is the whole reason to move an image into PNG before editing rather than after, and it is exactly what an AVIF cannot give you — every re-save of a lossy format shaves a little more off.

The part that is not a guarantee is the trip in. AVIF commonly codes 10 or 12 bits per channel; PNG is capable of 16; what this page writes is 8, in sRGB. The narrowing happens in the browser, which decodes the AVIF into an ordinary canvas, and a canvas is 8-bit. So the PNG is a perfect record of an already-narrowed picture. On anything headed for a screen you will never see it. On a smooth gradient you are about to stretch hard in an editor, the banding you find later started here, not in your editing.

The transparency, by contrast, does come across intact. AVIF keeps its alpha as a separate monochrome plane and PNG stores an alpha value per pixel, so the band of partly-transparent pixels along a cut-out edge — the thing that makes it look cut out rather than stamped out — arrives with its values unchanged. Nothing is composited onto a background on the way, because there is no background to composite onto.

When PNG is the right stop for an AVIF

AVIF stores transparency, and so do PNG and WebP. JPG does not. Convert a transparent AVIF to JPG and the see-through parts silently become white, which usually goes unnoticed until the image is placed on a coloured background.

PNG is also the right stop for an image entering an editing workflow. It is lossless, so opening, editing and saving does not shave a little off each time.

An animated AVIF converts to its first frame only, since PNG in the form most software reads holds one picture.

PNG questions specific to AVIF

Why is the PNG so much bigger than the AVIF?

They compress in fundamentally different ways. AVIF uses video compression techniques on the picture; PNG only looks for exactly repeating patterns, which photographs do not contain, so it ends up keeping nearly every pixel. The PNG size follows the picture, not the AVIF.

Is the PNG 16-bit?

No, 8 bits per channel in sRGB. The AVIF is decoded through a browser canvas, which is 8-bit, so a 10-bit or HDR AVIF is narrowed before the PNG is written.

Is PNG or WebP the better target?

WebP if the size matters, since it keeps transparency at a fraction of the size. PNG if you need every save from here on to be exact, or the software ahead of you insists on it.

Does this work for an animated AVIF?

Only the first frame. AVIF can hold animation and PNG, in the form most software reads, cannot.

The lighter alternative

AVIF to JPG The newest web format, turned into the one everything reads.
HEIC to PNG For when the next tool in the chain insists on PNG.
WebP to PNG The one to pick when the image has a transparent background.
JPG to PNG When something downstream will only take a PNG.

Or open the image converter to pick any combination, and the image compressor when the problem is size rather than format.
