What is a AVIF to PNG?

An AVIF to PNG Converter takes an image saved in the AVIF format, built on the AV1 video codec and known for producing some of the smallest file sizes of any modern image format, and re-encodes it as a widely compatible PNG. AVIF is increasingly used by websites to cut bandwidth and speed up page loads, but many image editors, older applications, and document formats don't yet support opening AVIF files directly.

This tool performs the conversion entirely in your browser, relying on the browser's native AVIF decoder where supported: it draws the decoded image onto a canvas and exports it as PNG, no upload, no server round-trip. It pairs naturally with the WebP to PNG Converter and JPG to PNG Converter if you're standardizing a mix of modern image formats into PNG.

Why Use an AVIF to PNG Converter?

Images downloaded from AVIF-serving websites often need to move into tools that predate AVIF support, desktop image editors, older presentation software, or upload fields that only list PNG and JPG. Converting on demand avoids searching for AVIF-compatible software just to open a single file.

Two concrete situations this solves: converting an AVIF image saved from a website into PNG so it opens correctly in an editor without AVIF support, and preparing an AVIF asset for a platform or document format that requires a more universally recognized file type.

Who Should Use This Converter?

  • Designers and content creators who saved an image from a modern website as AVIF but need PNG for tools without AVIF support.
  • Developers converting AVIF assets into PNG for platforms or build pipelines that don't yet handle AVIF.
  • Writers and researchers standardizing downloaded AVIF images into PNG for consistent handling across documents.
  • Anyone archiving images long-term, where PNG's broader, longer-established software support is preferable to AVIF's newer, narrower support.
  • Users comparing modern formats who want to check AVIF's file size against an equivalent WebP to PNG conversion.

What Insights Does the AVIF to PNG Converter Give You?

Once converted, the tool shows your Original (AVIF) and Converted (PNG) side by side, along with the file size of each and the image's pixel dimensions, useful for confirming the result looks correct and gauging how much larger the lossless PNG is compared to the highly compressed AVIF source.

Because transparency carries over automatically, there's no background setting to configure for this conversion, any alpha channel in the AVIF is preserved pixel-for-pixel in the PNG output.

How to use this AVIF to PNG calculator

  1. Drag and drop a .avif file onto the upload area, or click it to browse your device.
  2. Review the file preview showing the image's dimensions and file size.
  3. Click Convert to PNG.
  4. Compare the Original (AVIF) and Converted (PNG) previews and file sizes side by side.
  5. Click Download PNG to save the file, or Copy PNG to copy it directly to your clipboard.
  6. Click Change to start over with a different file.

Formula & Methodology

The browser decodes the AVIF's AV1-based compressed data into a raw RGBA bitmap, draws that bitmap onto an HTML canvas, then calls the canvas's PNG export (canvas.toBlob(..., "image/png")) to compress it losslessly. This relies entirely on the browser having a built-in AVIF decoder, there's no fallback library, which is why decoding can fail on unsupported or very old browsers.

For example, a 1920×1080px AVIF photo at 90KB will typically produce a PNG in the 2–4MB range once re-encoded, since PNG's general-purpose compression can't match AVIF's specialized, highly efficient image compression, the size increase reflects PNG's compatibility trade-off, not any change in visual content.

Frequently Asked Questions

It decodes an AVIF image, a newer image format built on the AV1 video codec, using your browser's native decoder, draws it onto an HTML canvas, and re-encodes the pixel data as a lossless PNG file. Any transparency in the source AVIF is preserved in the resulting PNG.
The entire conversion runs in your browser using the Canvas API, and the file never leaves your device. This makes the tool safe for images you'd rather not send to a third-party server.
AVIF produces very small file sizes, but many image editors, older software, and platforms don't yet support opening it directly, while PNG works almost everywhere. Converting to PNG trades some file-size efficiency for compatibility with tools that don't yet understand AVIF.
Current versions of Chrome, Firefox, Edge, and Safari all support decoding AVIF, which is what makes this in-browser conversion possible. If the conversion fails, your browser or its version may not support AVIF, try updating it or use a different browser.
If the source AVIF was saved losslessly, no quality is lost, PNG is also lossless, so pixels transfer exactly. If the AVIF used lossy compression, whatever detail was already discarded stays discarded; PNG can't recover it, but it won't introduce any further loss.
Yes, AVIF supports an alpha channel just like PNG, and this tool preserves any transparent or semi-transparent pixels exactly when re-encoding to PNG. No background color is needed for this conversion.
Drag and drop your .avif file onto the upload area, or click it to browse your device, then click Convert to PNG. The converted PNG appears next to your original file within moments, ready to download or copy.
AVIF typically compresses images significantly smaller than WebP, JPG, or PNG at comparable visual quality, which reduces bandwidth and speeds up page loads, a growing reason modern sites adopt it for photos and hero images. Converting back to PNG is useful when you need to move an AVIF asset into a general-purpose editing or sharing context.
You can upload an AVIF up to 15MB, which comfortably covers typical web assets and photos. Very large files may take a moment longer to decode and re-encode.
Yes, the Copy PNG button copies the converted image directly to your clipboard in supporting browsers, so you can paste it straight into another application. If your browser doesn't support clipboard image writes, use Download PNG instead.
Almost always yes, often substantially, AVIF's AV1-based compression is among the most efficient available for images, so converting to PNG typically increases file size considerably. This is the trade-off for gaining PNG's much broader software compatibility.
