How this works in your browser
Current browsers decode AVIF natively, which is what makes this conversion possible without shipping a decoder. The image is drawn onto an HTML5 canvas using that built-in support and exported through the browser's PNG encoder. Both formats carry an alpha channel, so per-pixel transparency maps straight across rather than being flattened onto a background. The size increase comes from a genuine difference in approach: AVIF inherits block prediction and transform coding from the AV1 video codec and discards detail the eye is unlikely to notice, while PNG stores every pixel exactly using lossless DEFLATE compression.
AVIF to PNG vs. traditional online converters
| Feature | AVIF to PNG (in-browser) | Traditional online converters |
|---|---|---|
| File upload required | No - never leaves your device | Yes - file is sent to a server |
| Processing queue | None - starts instantly | Often, especially at peak times |
| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |
| Account required | No | Often, for anything beyond a trial |
Who uses AVIF to PNG
Opening a downloaded image
Convert an AVIF saved from a website into something your photo viewer or editor will actually open.
Feeding older design software
Get a modern web image into applications and print workflows that have no AVIF support.
Preserving transparency
Move an AVIF graphic or logo into PNG without flattening its transparent areas onto a solid colour.
How to use AVIF to PNG
- 1
Open the AVIF to PNG converter
Go to tools.slaytic.com and open the AVIF to PNG tool. No sign-up or account required.
- 2
Drop your AVIF file
Add the .avif image. Your browser decodes it natively, so nothing needs to be uploaded or installed.
- 3
Download the PNG
Save the losslessly re-encoded result, with any transparency preserved.
Frequently asked questions
Will the file size increase?
Usually yes. AVIF is a highly efficient modern format, so PNG output is typically larger for the same image.
Is transparency preserved?
Yes, if the source AVIF has an alpha channel, it carries over to the PNG output.
Which browsers can open my AVIF file for this conversion?
Any current version of Chrome, Firefox, Safari, or Edge can decode AVIF for this tool.
What is AVIF and why did I end up with one?
AVIF is a modern image format built on the AV1 video codec, and it compresses considerably better than JPEG or even WEBP at similar quality. Sites use it to cut page weight, which is why an image saved from the web increasingly arrives as .avif. Browsers read it happily; a lot of desktop software still does not.
Why would I convert to PNG rather than JPG?
Choose PNG when the image has transparency to preserve, or when it is a graphic, logo or screenshot with sharp edges that JPEG would soften. Choose JPG for photographs where the smaller file matters more than pixel-exactness.
How much bigger will the PNG be?
Often several times larger, and that is expected rather than a fault. AVIF is one of the most efficient formats available and PNG is lossless with no perceptual shortcuts, so undoing that compression is the price of compatibility.
Is my image uploaded anywhere?
No. Decoding and re-encoding both happen inside your browser tab.
