This converter turns AVIF images into PNG files without uploading anything. The conversion runs inside this page using your own device's processor, so your photos never leave your computer — there is no server copy to worry about, no queue to wait in, and no limit on how many files you convert.
AVIF is a modern format built on the AV1 video codec, producing the smallest files of any widely supported image format. All current browsers decode AVIF. Outside the browser, support is still thin — which is usually why you need it converted. PNG, by contrast, universal across browsers, operating systems and design software.
AVIF turns up when you save an image from a site that has modernised its delivery. Browsers handle it fine, but nearly everything else — desktop editors, office software, print services — does not. PNG is the pragmatic choice when the file has to leave the browser.
How to convert AVIF to PNG
- Add your AVIF files. Drag them onto the box above, click to browse, or paste an image straight from your clipboard. You can add as many at once as you like.
- Adjust the settings if you need to. The defaults suit most images. PNG is lossless, so there is no quality setting to adjust.
- Download the PNG file. Each file gets its own download button as soon as it finishes, and you can pull the whole batch down as a single ZIP.
What changes when you convert AVIF to PNG
Every format conversion involves trade-offs, and vague tools hide them. Here is exactly what happens to your image in this particular conversion.
- Transparency is preserved: both AVIF and PNG carry a full alpha channel.
- PNG is lossless, so nothing further is lost — but it also cannot restore detail that AVIF already threw away. Expect the PNG file to be considerably larger than the original despite containing the same visible image.
What happens to the file size
Measured, not estimated: two 1200 x 800 pixels references — a photograph and a flat-colour graphic — put through this converter.
| Reference image | As AVIF | As PNG | Change |
|---|---|---|---|
| Photograph | 104 KB | 2.06 MB | +1920% |
| Graphic with text | 4 KB | 83 KB | +2263% |
Yours will differ: size depends more on what is in the picture than on the formats involved.

- Royalty-free and supported in all current browsers
Limitations
- Encoding is computationally expensive — noticeably slower than JPG or PNG

- Perfect for text, screenshots, line art and flat colour
Limitations
- Much larger than JPG or WebP for photographs
- No animation (APNG exists but is patchily supported)
- No quality dial — you cannot trade detail for size
Is it safe to convert AVIF online?
Here, yes — and you can check rather than trust. Open your browser’s developer tools, switch to the Network tab and convert a AVIF file: no request carrying your image is made. Disconnect from the internet after this page has loaded and the converter still works, which would be impossible if a server were doing the conversion.
That is worth verifying wherever you convert, because most online converters do upload, and AVIF files are so often personal photos and documents people would not hand to a stranger. Once a file is on somebody else’s server you are relying on a privacy policy rather than on anything you can observe. We wrote up how to tell a safe converter from a risky one in more detail.
Frequently asked questions
How do I convert AVIF to PNG?
Drag your AVIF file onto the box above, or click it to browse. The conversion starts immediately in your browser and the PNG download appears within a second or two for most images. You can drop in a whole folder of files at once and download them together as a ZIP.
Are my AVIF files uploaded to a server?
No. The conversion happens locally in your browser, so your files are never transmitted anywhere — the tool even works with the network disconnected once the page has loaded. That is also why there is no file size or file count limit: nothing costs us anything per conversion. The practical ceiling is your own device's memory, which on a phone means very large images may fail.
Will converting AVIF to PNG reduce the quality?
No further quality is lost — PNG is lossless. Bear in mind it also cannot recover detail the original AVIF had already discarded, and the resulting file will be noticeably larger.
What is the difference between AVIF and PNG?
AVIF is a modern format built on the AV1 video codec, producing the smallest files of any widely supported image format. PNG is the lossless format of choice for screenshots, logos and any image that needs a transparent background. In practice the choice comes down to compatibility: all current browsers decode AVIF. Outside the browser, support is still thin — which is usually why you need it converted. Meanwhile universal across browsers, operating systems and design software.
