When you need an AVIF in a format that older software accepts but you are not willing to give up transparency or lose any detail, PNG is the right destination. Unlike JPG, PNG keeps an alpha channel, so a logo, icon or cut-out subject that sat on a transparent background in the AVIF still floats cleanly over whatever you place it on. And because PNG is lossless, the picture is carried across exactly, with none of the softening that a lossy re-encode would introduce.
The tool decodes each AVIF and writes a standard PNG, with no quality setting to fuss over precisely because nothing is being thrown away. That makes it the safe choice when the image is going into an editor for further work, when it has flat colour and crisp edges like UI assets or diagrams, or when a tool on the receiving end simply demands PNG.
There is a second, quieter reason PNG suits some AVIF files better than JPG. AVIF can store images with more than the usual eight bits per colour channel, which is how it holds smooth gradients without visible banding. PNG can carry that extra precision too, whereas a JPG would flatten it back to eight bits. So for a graphic with delicate shading, a render, or anything where you have seen banding appear after a careless conversion, PNG protects the result. The same goes for interface elements and exported app assets, where a single misplaced compression artefact around an icon's edge is immediately obvious.
Reach for PNG over AVIF to JPG whenever transparency has to survive, whenever the image will be edited and re-saved repeatedly, or whenever it is line art and graphics rather than a photograph. The one cost is file size: a lossless PNG of a detailed photo can be large, so for photographic content headed somewhere that does not need transparency, the JPG route is often the more sensible pick.
If you later need to send the picture back to a small, modern format, PNG to AVIF makes the return trip while keeping the transparency intact.
Drop in a single image or several at once.
The AVIF is unpacked straight into a lossless PNG, transparency and all. No settings involved.
One PNG downloads directly; convert several and they arrive zipped together.
Yes. PNG supports a full alpha channel, so any transparent or partly transparent areas in your AVIF are preserved exactly. This is the main reason to choose PNG over JPG, which would fill those areas with white.
None from the PNG side. PNG is lossless, so the decoded AVIF is written pixel for pixel. The only detail ever lost was whatever the original AVIF encoding already removed, and converting cannot bring that back.
Pick PNG when transparency has to stay, when the image is graphics or text rather than a photo, or when it will be edited repeatedly. JPG is the better call only for photographs that do not need a transparent background and where a smaller file matters.
It can be, especially for photographic AVIFs, because lossless storage takes more room than AVIF compression. If the image is a photo that does not need transparency, AVIF to JPG will give you a far smaller file, since a lossy JPG is always lighter than a lossless PNG.
Only the container changes. The pixels, the dimensions and the transparency are written through unchanged, because PNG is lossless, so what you get is the same picture the AVIF held, now in a format far more programs can open.
