HTMLImageElement: decoding property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.
The decoding property of the HTMLImageElement interface provides a hint to the browser as to how it should decode the image. More specifically, whether it should wait for the image to be decoded before presenting other content updates or not. It reflects the <img> element's decoding content attribute.
