How to Convert PNG to AVIF Online
PNG to AVIF takes a PNG, transparency included, and writes an AVIF that is a fraction of the size. Logos, icons and screenshots with see-through backgrounds keep them, because AVIF supports an alpha channel. You set a quality slider, the page shows the new size against the old, and you download. The usual reason for keeping a PNG on a website no longer applies.

Tips and Good to Know
-
AVIF is lossy at any quality setting. A pixel-exact asset such as a sprite sheet or a UI icon set should stay PNG, or go to lossless WebP with PNG to WebP.
-
Sharp text and thin lines in a screenshot can smear at low quality. Push the slider up and compare before shipping it.
-
Anything outside a browser is a risk. Design tools, older image viewers and most email clients still ignore AVIF, so keep the PNG as your master copy.
Frequently Asked Questions
Answers to common questions about this tool.
Do I need to install anything to convert PNG to AVIF?
No. PNG to AVIF runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.
Is it safe to convert PNG to AVIF online?
Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.
Does PNG to AVIF reduce my photo’s quality?
Converting and cropping keep quality close to the original. Compressing trades a little detail for a much smaller file, and a lighter setting keeps more of it. Compare the preview with your original before saving.
Will my photo be accepted by the exam form?
The exam photo tools follow the size, dimensions and file weight given in the official notice. Always read the latest notice too, because boards sometimes change their rules between years.
Can I edit pictures with PNG to AVIF straight from my gallery?
Yes. Pick a photo from your gallery or take one with the camera, then save the result back to your phone. Everything works in the browser, so there is no app to install.
Is PNG to AVIF free with no watermark?
Yes. Use it for as many pictures as you need without an account, and each image comes back without any logo or mark from the site.
