AVIF to PNG Converter

AVIF delivers strong lossy compression but its decoder support is absent in legacy desktop software, most email clients, and platforms built before 2021. PNG is lossless, universally supported, and preserves alpha channel transparency without introducing compression artefacts — making it the correct conversion target when image quality, editability, and compatibility all matter simultaneously.

This converter runs entirely in the browser. Your AVIF file is decoded by the browser’s native AVIF codec, drawn to a canvas element, and exported as lossless PNG. No file is uploaded to any server.

When PNG Is the Right Target Format

Transparency preservation is the most common reason to convert AVIF to PNG rather than AVIF to JPG. PNG supports an 8-bit alpha channel, which encodes full per-pixel transparency ranging from completely transparent to completely opaque. Product cut-outs, logos with non-rectangular shapes, and UI elements that sit above variable backgrounds all require this capability.

Image editing workflows also favour PNG. Design tools including Figma, Sketch, Photoshop, and Illustrator read PNG without codec dependencies. An AVIF file may require an additional codec installation to open in these applications; a PNG opens natively in every version released since the format was standardised in 1996.

Print prepress workflows that require RGB colour fidelity without compression loss use PNG as a web-safe intermediate before converting to TIFF or PDF. AVIF’s lossy encoding, even at high quality settings, introduces sub-pixel differences that accumulate across repeated encode-decode cycles in post-production pipelines.

AVIF vs PNG: Format Comparison

What the Conversion Produces

The Canvas API decodes the AVIF to raw pixel data and re-encodes it as PNG using DEFLATE lossless compression. Transparency from the AVIF source is preserved exactly in the PNG output, because both formats support a full 8-bit alpha channel.

PNG does not have a quality setting. The output is always losslessly compressed, which means the PNG file will be larger than the AVIF source. For photographs, the PNG can be two to four times larger than an equivalent-quality AVIF. For graphics with flat colour, text, and hard edges, the ratio is closer to 1.5 to 2 times larger.

How the Converter Works

Drop or select your AVIF file and click Convert. The browser decodes the AVIF, draws it to an offscreen canvas, and exports the pixel data as a lossless PNG file. The download starts once the export completes. All processing runs locally — nothing leaves your browser tab.
