Convert AVIF to PNG, Universal Compatibility With Alpha

Drop an AVIF onto the upload area or click it to select a file. The browser decodes the AVIF natively and re-encodes it as PNG using its built-in support. Because both steps are native, there is no module to load and no warm-up delay. For most photos the conversion finishes in under a second. When the result is ready, the stats line shows the original AVIF size next to the new PNG size, and the PNG will be noticeably larger. Click Download to save it to your device with the same base name and a new .png extension. The PNG is ready to open in any app on your machine immediately.

Both AVIF and PNG support full transparency, so the conversion carries every transparent area through unchanged. Nothing is flattened and no background fill is added. If your AVIF holds a cut-out subject on a transparent canvas, the PNG you download has the same cut-out on the same transparent canvas, ready to layer into a design, a slide deck, or a web layout over any background. This is the opposite of converting to JPG, which has no transparency support and replaces every see-through area with a solid color. AVIF to PNG keeps the mask intact, which is the main reason to choose it over AVIF to JPG when your asset has transparency.

AVIF reaches its small size through compressed encoding, discarding information the eye does not notice and storing a compact representation. PNG keeps every detail exactly as decoded, with no further quality loss. When you convert AVIF to PNG, the converter expands the compact AVIF back into full image data and writes it without quality reduction, which is inherently larger. A typical ratio is three to ten times the AVIF size, depending on the content. This is not a sign anything went wrong. You trade file weight for universal compatibility and an exact intermediate that any tool can open and edit without another round of quality loss layered on top.

Your choice comes down to who opens the file next. AVIF excels on a modern website where the audience uses up-to-date browsers and every saved byte improves page speed. PNG is the right pick when the destination does not yet read AVIF, including older viewers, email clients, Microsoft Word and similar office tools, forum software, and content platforms that reject AVIF on upload. PNG is also the right format when you plan to keep editing, because re-saving a PNG never adds further quality loss the way a re-saved compressed format would. AVIF is your delivery format, and PNG is your working and compatibility format.

It depends on how many files you convert. Convert a single AVIF and the whole thing runs on your device: the browser's built-in image engine decodes the file and writes it as PNG, with nothing crossing the network. You can verify this by opening the Network panel in your developer tools and converting one file: you will see zero outbound image requests during the operation. Convert two or more at once and RoundCut sends them to our server, which decodes and re-encodes them in one pass and returns a single download. Files handled on the server are processed and then removed within about 2 hours. We do not keep your images, we do not ask for an account, and we do not use them for anything other than the conversion you requested. Either way the output is the same PNG, with the same transparent areas intact.

AVIF is a recent format that many tools adopted only lately. As of 2026, these commonly reject it: most email clients including Gmail and Outlook, Microsoft Word and other Office apps, pre-2025 Adobe Photoshop, several content systems including some versions of WordPress and Squarespace upload widgets, some forum software, and every version of Internet Explorer. Modern browsers, Chrome 85 and later, Firefox 93 and later, Safari 16.4 and later, and Edge 121 and later, all read AVIF natively. If the tool you need sits in the first list, converting to PNG is the fastest way to make the file work where you need it.
