About the AVIF to PNG Converter

The ByteTools AVIF to PNG Converter opens a modern AVIF image and re-saves it as a universally supported PNG file. AVIF delivers superb compression, but plenty of software — older editors, office suites, CMS uploaders and enterprise systems — still refuses it. Converting to PNG makes the picture usable everywhere.

Unlike a JPG conversion, PNG is lossless and supports an alpha channel, so this tool keeps transparent backgrounds exactly as they are in the AVIF. That matters for logos, UI assets and product cutouts where flattening to white would ruin the file.

Decoding and conversion happen 100% locally: your browser's built-in AVIF decoder reads the file and the canvas API re-encodes it as PNG. Nothing is uploaded, so your images stay on your device.

Frequently asked questions

Why convert AVIF to PNG instead of JPG?

PNG is lossless and keeps transparency, so nothing is degraded or flattened in the conversion. Choose PNG when the image has transparent areas or sharp graphics; choose JPG only when you need the smallest possible photo file.

Why is the PNG so much bigger than the AVIF?

That is expected. AVIF uses modern lossy compression that can be ten times more efficient than PNG's lossless compression. The PNG stores every pixel exactly, which costs space — the trade-off is universal compatibility.

Does AVIF to PNG conversion lose quality?

No further quality is lost. Whatever detail the AVIF file contains is decoded and written to PNG pixel-for-pixel. Any softness you see was already baked into the AVIF when it was first compressed.

My AVIF file will not open — why?

This tool relies on your browser's built-in AVIF decoder. All current versions of Chrome, Edge, Firefox and Safari support it, but older browsers do not — updating your browser fixes it. Some rare AVIF variants (e.g. certain animated files) may also fail to decode.

Are my AVIF files uploaded to a server?

No. Decoding and PNG export both run inside your browser using the canvas API. The file never leaves your computer, which makes the tool safe for private photos and unreleased assets.
