Convert AVIF to PNG With Full Transparency and Lossless Quality

AVIF is a cutting-edge image format with outstanding compression, but its newness means many applications and workflows still can’t read it. Converting AVIF to PNG gives you a universally supported, lossless file that opens in every editor and application — with full transparency preserved. This free converter runs entirely in your browser.

Why PNG Makes a Great Destination for AVIF

  • Universal support — every image editor, operating system, and application opens PNG without issue.
  • Transparency preserved — both formats support full alpha channels, so transparent pixels come through perfectly.
  • Lossless fidelity — PNG captures the exact output of the AVIF decoder, with no further quality loss.
  • Editing-friendly — PNG is ideal when you plan to manipulate the image further in Photoshop, GIMP, Figma, or similar tools.

How This Tool Converts AVIF to PNG

Your browser decodes the AVIF file natively (requires a modern browser — Chrome 85+, Firefox 113+, Safari 16.4+, or Edge), then the tool re-encodes the image as lossless PNG. Output is optionally optimized with oxipng, an open-source PNG compressor that finds the smallest possible lossless encoding without changing a single pixel.

About File Size

PNG output will be significantly larger than the AVIF source — typically 3–10x. AVIF is one of the most efficient formats ever designed, while PNG prioritizes lossless fidelity above all else. That’s the trade-off for compatibility and edit-friendliness. Use the Compression slider to let oxipng shave 10–40% off the PNG size without any quality loss.

Private & Offline

All conversion happens inside your browser using WebAssembly. Your AVIF files never leave your device. The tool works offline after the first page load and has no file size limits, no account requirements, no watermarks, and no usage caps.

FAQ

Frequently Asked Questions

AVIF is a newer format not yet universally supported by image editors, legacy applications, and older operating systems. Converting to PNG gives you a lossless, universally compatible file that works everywhere — ideal for further editing, print workflows, and applications that reject AVIF files.

Yes. Both AVIF and PNG support full alpha transparency, so any transparent or semi-transparent pixels in your AVIF will be preserved perfectly in the converted PNG. This makes PNG an excellent destination format when you need a transparent background in applications that do not support AVIF.

The PNG encoding itself is lossless — it captures the exact pixels produced by the AVIF decoder. If your AVIF was encoded losslessly, the output PNG will be pixel-identical. If the AVIF was lossy, the PNG preserves that lossy result without any further quality loss.

Yes, usually dramatically. AVIF is one of the most efficient image formats available, while PNG prioritizes lossless fidelity. Expect the PNG output to be 3–10x larger than the AVIF source. Use the Compression slider to apply oxipng lossless optimization, which can shave 10–40% off the PNG size without any quality loss.

If the tool reports a decode failure, your browser may not support AVIF or the file may be corrupted. AVIF requires Chrome 85+, Firefox 113+, Safari 16.4+, or Edge. Update your browser to the latest version if decoding fails. Animated AVIF sequences or uncommon codec profiles may also be unsupported.
