Convert AVIF to PNG
When an AVIF has a see-through background, or you plan to keep editing it, PNG is the safe copy to make: it keeps the transparency and adds no compression loss of its own. Octoolo converts on your computer, so the picture never travels anywhere.
How to convert AVIF to PNG
- 1
Open the AVIF
Drop the .avif onto Octoolo's Photo Editor, or press Ctrl O and find it.
- 2
Make changes first, if any
Crop it, turn it or tidy it up. Each change can be undone, and the .avif file itself is never altered.
- 3
Choose PNG
Press Export, click PNG next to Kind of file, and keep the full size under Size.
- 4
Save it
Press Save in that window, then pick a folder and a name in the Windows Save window.
- 5
Check the transparency
Drop the new PNG back onto the Photo Editor if you want to be sure: small light squares show through wherever it is see-through.

PNG or JPG for an AVIF?
Both open everywhere, so choose by what the picture is and what happens to it next:
- Logos, icons, illustrations and cut-outs: PNG. It keeps the clear background, the crisp edges and the flat colors exactly.
- Screenshots and pictures with writing: PNG, so letters stay sharp.
- Stickers and emoji-style art for chats: PNG, which keeps the clear outline around them.
- Photos you want to send or upload: JPG. A photo stored as PNG is heavy, and JPG keeps it small.
- Pictures you will keep working on: PNG now, and a JPG at the very end if you need one.
When in doubt and the file size does not matter, PNG is the copy that loses nothing. If the picture is headed back to a website, a WebP made from the PNG later will be much lighter.
How big the PNG will be
AVIF is a heavily compressed format, and PNG does not compress with loss at all, so expect the PNG to be larger. How much larger depends on what is in the picture:
- Flat graphics and illustrations usually stay manageable, because PNG packs areas of one color very tightly.
- Photos can grow many times over, since every pixel differs a little from the next and all of that is stored.
Export shows the estimated size before you commit. If it is too big for where the picture is going, pick a narrower width under Size (the list runs from 3840 down to 512 pixels, as far as the picture is wider), or save a JPG after all. A PNG has no quality slider to fall back on, so its width is the one setting that changes its size.
Do the editing in between
A PNG copy makes a good working file. Because PNG never throws detail away, you can open it, change it and save it as often as you like without it wearing out, which a JPG cannot promise.
The Photo Editor has the tools most of these jobs need, and they work on the AVIF before you even export: crop to a shape such as Square or 16:9, turn or straighten it, brighten it with Image › Auto tone and color, add text in any font on your PC, or put a border around it. Every change is a step you can undo, and adjustments stay editable layers.
When you are done, Export draws the PNG from the full-size AVIF, not from the view on screen, and the .avif stays as it was.
Quicker for a plain conversion
If there is nothing to change, Convert pictures on the Photo Editor's start page skips the editor. Choose the AVIF, and the tool shows it next to the PNG with both sizes in pixels and in KB. For an AVIF, both PNG and Same under Format give a PNG, since Octoolo does not write AVIF files. Press Save PNG, and the Windows Save window suggests the original name ending in .png.
It takes one picture or many and keeps transparency in PNG. It also leaves out location, camera and date details, the same as every picture Octoolo saves.

Questions, answered
Does the PNG keep the AVIF's transparent background?
Yes. See-through parts stay see-through in a PNG, including soft edges and shadows.
Will the PNG look exactly like the AVIF?
For ordinary pictures, yes: PNG stores the pixels as they are. An HDR AVIF comes out in standard range, because the PNG is saved that way.
Can Octoolo turn the PNG back into an AVIF?
No. Octoolo exports JPG, PNG, WebP and PSD, not AVIF. For a light file for the web, WebP is the closest choice.
Will older programs open the PNG?
Yes. PNG has been around since the mid-1990s and opens in practically every program on Windows, as well as on phones and the web.
Is there a limit on picture size?
The Photo Editor holds pictures up to the largest size your graphics card takes, 16,384 pixels a side on most PCs. Very large pictures take longer to export, and their PNGs can be large.
Does it need the internet?
No. The Photo Editor runs on your own PC, and the picture stays there, so there is no waiting for a big file to upload either.
