AVIF to PNG Converter

Convert one static AVIF into a real PNG locally. The decoded alpha channel stays transparent when the browser can decode the source.

Static AVIF only · up to 25 MiB · 40 megapixels · native AVIF decoding required

Private: the image is processed locally

How to convert AVIF to PNG

  1. Choose one valid static AVIF within the 25 MiB and 40 megapixel limits.
  2. Let the browser validate and decode the AVIF locally, then press Convert to PNG.
  3. Inspect the verified PNG preview and download the real file.

AVIF vs PNG

AVIF is a modern compressed image format, while PNG is a widely supported lossless format for decoded pixels. PNG is usually larger; this converter does not restore detail already lost in a lossy AVIF.

Decoded transparency stays transparent

Transparent and semi-transparent pixels decoded from the AVIF are written to the PNG alpha channel. No white or black background is composited. PNG encoding is lossless for the decoded pixel result.

Browser AVIF support

The tool uses native browser AVIF decoding and an offline capability probe. If the browser cannot decode AVIF, it shows a clear error and does not upload the file or use a server fallback.

Static AVIF only

AVIF sequences and animated AVIF are rejected before conversion. PicRecast never silently exports only the first frame.

HDR, wide gamut, and bit depth

Browser decoding and Canvas may tone-map HDR, convert wide-gamut color, or reduce high-bit-depth data. The page does not promise exact HDR or color-management preservation.

Metadata and profiles

The browser PNG pipeline does not guarantee preservation of ICC, NCLX, EXIF, XMP, or other AVIF metadata. Keep the original when those details matter.

Why the PNG may be larger

PNG uses lossless encoding and is often much larger than a compressed AVIF. PicRecast reports the real source and output sizes and makes no compression claim.

Privacy

Validation, capability detection, decoding, PNG encoding, preview, and download run in your browser. The image is not sent to PicRecast, an image API, an AI provider, or analytics as a custom property.

Limitations

This tool handles one static AVIF at a time. It does not resize, crop, optimize PNG palettes, preserve metadata, guarantee HDR or wide-gamut output, run on a server, or convert sequences.

Frequently asked questions

Will AVIF transparency stay transparent?

Decoded transparent and semi-transparent pixels remain in the PNG alpha channel. No background fill is applied.

Why is the PNG larger than the AVIF?

PNG is lossless for the decoded pixels and is often less compact than AVIF. A larger file is normal.

What if my browser cannot decode AVIF?

The offline capability probe reports that AVIF is unsupported. No result or download is created, and the file is not uploaded.

Can I convert an AVIF sequence?

No. AVIF sequences and animated AVIF are rejected rather than converted as a silent first frame.

Are HDR, wide-gamut color, and metadata preserved?

Not guaranteed. Browser decode and Canvas may convert color or bit depth, and the re-encoded PNG may omit source metadata.
