Convert PNG to AVIF
AVIF is the current end-game for image compression: the same PNG graphic or screenshot typically lands 70–90% smaller, with transparency preserved. Since every major browser added support, the only real cost left is a slightly slower encode.
Open converterHow to convert PNG to AVIF
- 1
Open the PNG
Transparent artwork is fine — AVIF carries full alpha, so logos and cut-outs don't need flattening the way a JPG conversion would force.
- 2
Set quality, then give it a second
Choose a moderate slider setting (screenshots dislike rock-bottom quality) and let the AV1 encoder chew for a moment — that extra effort is where the tiny files come from.

Download and compare
Click Convert & download, check the new size against the original, and keep the PNG as your lossless master for any future re-exports.
Why convert PNG to AVIF?
-
The biggest savings of any format here — PNGs routinely shrink to a tenth of their size or less.
-
Alpha transparency survives, so cut-outs, logos, and UI art don't need flattening.
-
Chrome, Firefox, Safari, and Edge all render AVIF natively now; the compatibility excuse has expired.
-
For image-heavy pages, the bandwidth drop is large enough to show up in both speed scores and hosting bills.
What actually happens to your file
Encoding runs through a WebAssembly AV1 encoder in your browser, which is honest work: expect a second or two for a normal image rather than the instant export of JPG or WebP — that extra effort is precisely where the compression advantage comes from. The output is lossy, governed by the quality slider, so keep your PNG as the master file. Where AVIF stumbles is razor-sharp single-pixel detail at very low quality settings; for screenshots, stay at moderate quality rather than chasing the minimum byte count.
Frequently asked questions
Can browsers actually display AVIF now?
Yes — Chrome since 2020, Firefox since 2021, and Safari since 2022 (macOS Ventura / iOS 16). For public websites today, AVIF works without a fallback, though very old installed browsers won't show it.
Why does AVIF encoding take longer than other formats?
AVIF borrows its compression from the AV1 video codec, which spends far more computation searching for ways to shrink the data. A couple of seconds of encoding buys a file several times smaller — that's the trade.
Does AVIF keep my PNG's transparency?
Yes, including partial alpha like soft shadows. The compression applies to transparent images just as effectively — something JPG could never offer.
