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
- Choose one valid static AVIF within the 25 MiB and 40 megapixel limits.
- Let the browser validate and decode the AVIF locally, then press Convert to PNG.
- 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.
