PNG to AVIF Converter
PNG to AVIF Converter encodes one PNG locally as AVIF while retaining decoded transparency.
Purpose and limits
What this tool does
Convert one PNG image into a compact static AVIF.
- Input
- One PNG up to 25 MiB and 16.7 million decoded pixels.
- Result
- One lossy 8-bit sRGB AVIF with decoded alpha preserved and metadata removed.
How to use it
- Choose one local PNG within the fixed limits.
- Set the AVIF quality and review the lossy color and metadata warning.
- Process locally and download the resulting AVIF.
Limitations
- AVIF encoding is lossy even at high quality.
- Decoded alpha is retained, but metadata and color profiles are removed and output is 8-bit sRGB.
- The self-hosted Worker/WASM runtime loads after explicit processing; physical mobile-device support is not claimed.
