Free PNG to AVIF converter

Why convert PNG to AVIF?

People convert PNG to AVIF because PNG keeps every pixel exactly, which makes photographs several times larger than they need to be, while AVIF cuts the same picture to a fraction of the size with no visible loss.

How to convert PNG to AVIF

1. Choose your PNG file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .avif. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .png file?

PNG is lossless: it stores every pixel exactly as it was, and supports a transparent background. It is the right format for screenshots, logos, diagrams, icons and anything with sharp edges or text. Photographs come out noticeably larger than they would as JPG.

What is a .avif file?

AVIF uses the AV1 video codec to compress still images, often landing at half the size of an equivalent JPG. Browsers display it well; most desktop software does not yet. Use it for pages you build, and convert it to JPG or PNG for anything you need to send to another person.

What to expect from this conversion

The image is decoded and re-encoded, so keep the quality slider at 85% or above — at that setting the difference is invisible to the eye. Transparency is flattened onto white for formats that cannot store it, such as JPG.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your PNG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about PNG to AVIF

Is this PNG to AVIF converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my PNG file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert PNG to AVIF online without downloading software?

Yes. This is an online PNG to AVIF converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

The image is decoded and re-encoded, so keep the quality slider at 85% or above — at that setting the difference is invisible to the eye. Transparency is flattened onto white for formats that cannot store it, such as JPG.

How do I convert PNG to AVIF on Windows, Mac or Linux?

The same way on all three: open this page in Chrome, Edge, Firefox or Safari, drop the PNG file, press Convert and download the AVIF. Nothing is installed and no admin permission is needed.

Can I batch convert several PNG files to AVIF at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Can I convert PNG to AVIF without ImageMagick or a script?

Yes — that is what this page is for. ImageMagick does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original PNG file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that PNG keeps every pixel exactly, which makes photographs several times larger than they need to be.
