AVIF to PNG Converter

AVIF is the web's newest image format

AVIF arrived as the still-image sibling of the AV1 video codec, and it is genuinely impressive: about half the size of a JPEG at comparable quality, with support for HDR, wide colour gamuts and a full alpha channel. Every current browser displays it, which is why so many sites now serve AVIF. The catch is everything around the browser — desktop editors, older operating systems, upload validators and print bureaus — has been much slower to catch up.

Converting for the tools that lag behind

That gap is exactly when you need AVIF to PNG. A PNG is the lowest common denominator of image formats: lossless, transparent-capable and opened by essentially every piece of software in existence. Decoding the AVIF and re-encoding it as a PNG gives you a file that will not be rejected by an old editor or a stubborn upload form, at the cost of a larger byte count — the price of lossless, universal storage.

What AVIF gives up on the way out

AVIF can carry high-dynamic-range and very wide colour data that PNG, as delivered here, folds back into the standard sRGB range. The visible effect is subtle — the brightest highlights and most saturated colours settle to what an ordinary screen shows — but it means an HDR AVIF does not become an HDR PNG. What you gain is a file that every application opens without a plug-in, which is usually the entire point of this conversion.

Reading a file your operating system refuses

The reason people reach for AVIF to PNG is rarely the format's quality and almost always a piece of software that will not open it — an older Photoshop, a government upload portal, a print shop's RIP. This page decodes the AVIF in the browser rather than relying on the operating system's codecs, so a file your desktop refuses still converts, and the result is a PNG those same stubborn tools accept first time.

Batch conversion, privately

Up to twenty files convert in one run, each up to 25 MB, processed one at a time so memory stays predictable, with a summary strip totalling the batch. Each result is named after its source with a .png extension. Nothing is uploaded: the decode, the re-encode and every download happen inside the tab, with no account and no watermark, because there is no server on the other end.

When to convert onward, and to what

If the AVIF decoded fine but the PNG is too heavy for where it is going, the lossless PNG is only a way-station — compress it or take it to PNG to WebP for delivery, and keep the AVIF as your true source. For an opaque photograph a PNG to JPG export is smaller still, though it drops the transparency that made you choose PNG in the first place. If you came here only because some tool rejected AVIF, check whether that same tool accepts AVIF to WebP output — WebP's support is wider than AVIF's and its files stay far lighter than a PNG, so it is often the more comfortable landing spot.
